To meet the pressing demand from the smart‑home and industrial‑automation markets for high‑performance, low‑loss, and thermally robust bidirectional thyristors, Guangdong Jiaxun Electronics Co., Ltd. has launched its next‑generation product—the BTA04A. Boasting exceptional performance and reliability, this device is an ideal choice for power‑control and conversion systems.

The Core Advantages of the BTA04A Bidirectional Thyristor

1. High voltage rating, suitable for high-voltage environments.
   The BTA04A features a reverse blocking repetitive peak voltage (VRRM) of up to 800 V and a forward blocking repetitive peak voltage (VDRM) of 600 V, ensuring stable operation in high‑voltage environments. Its rated voltage is designed to be 2 to 3 times the normal operating peak voltage, making it particularly well suited for high‑voltage power control and conversion systems.

2. High current capability, meeting medium-power requirements.
   This product has an on-state root-mean-square current (IT(RMS)) of 4 A, making it well suited for medium‑power power conversion and control applications. When selecting a device, ensure its current rating is 2 to 3 times the actual operating current to provide ample overload capacity, thereby guaranteeing efficient operation and reliable performance.

3. Flexible triggering methods with strong compatibility.
   The BAT04A supports both positive and negative pulse triggering and offers four trigger modes. Its gate trigger current (IGT) is as low as ≤35 mA, and its gate trigger voltage (VGT) is 1.5 V, ensuring compatibility with most driver circuits and providing flexibility and ease of use across diverse application environments.

4. Diverse packaging options to meet various installation requirements.
   To meet the installation requirements of various application scenarios, the BTA04A is available in three package types: TO‑220, TO‑220F, and TO‑252. These packages not only offer excellent thermal management but also accommodate compact designs in industrial equipment and consumer electronics.

5. Outstanding thermal performance, ideal for high-power applications.
   In high-power applications, thermal management is critical. The BTA04A boasts excellent thermal performance, with low thermal resistance and a high junction‑temperature rating, ensuring stable long‑term operation under heavy loads while maintaining low losses and high reliability.

6. Low on-state voltage drop, enhancing energy efficiency.
   The BTA04A’s low on-state voltage drop (VTM) characteristic effectively reduces conduction losses, thereby improving overall energy efficiency. This feature enables it to deliver outstanding performance in applications requiring long‑term continuous operation, further lowering the system’s energy consumption.

7. High voltage slew rate (dv/dt), ensuring circuit stability.
   The BTA04A features high dv/dt immunity, effectively preventing false turn‑on and ensuring circuit stability under high‑speed switching and voltage transient conditions, making it particularly well suited for harsh environments with severe voltage transients.

Wide range of application scenarios

The BTA04A bidirectional thyristor, with its outstanding performance, can meet the requirements of a wide range of applications and is particularly well suited for the following fields:

• Motor Control : Provides stable current and voltage control, ensuring efficient motor operation.

• Power converter : Achieve efficient power conversion under high-voltage conditions, reducing energy losses.

• Dimming control : Supports flexible triggering methods to meet smart home dimming requirements.
