STMicroelectronics 1.40 V Zener Diode Single 600 W Surface Mount DO-214AC (SMA) SMA6J40A-TR

The STMicroelectronics SMA6J40A-TR is a high-quality Zener Diode designed for electronic and industrial applications requiring voltage regulation and transient voltage suppression. It features a nominal Zener voltage of 40 V and is a single diode device, making it ideal for protecting sensitive equipment from voltage surges. The diode is housed in a compact DO-214AC (SMA) surface mount package, allowing designers to save valuable PCB space while ensuring robust protection.

This diode supports a maximum power dissipation of 600 W for short transient surges (10/1000 µs), making it suitable for protecting circuits against electrostatic discharges and electrical overstress. The device operates efficiently with very low reverse leakage current of just 200 nA, thereby minimizing power losses and improving circuit stability. It operates reliably across a broad temperature range from -55°C to 175°C, suitable for both commercial and industrial environments.

The SMA6J40A-TR supports both unidirectional and bidirectional configurations, providing flexibility in circuit design for various protection needs. Its physical dimensions of 5.35 mm in length and 2.45 mm in height support compact assembly in high-density PCB layouts. The planar technology ensures low leakage current and high junction temperature tolerance, enhancing device reliability and longevity. This makes it ideal for high-end equipment and switch-mode power supplies (SMPS).

Typical industrial, laboratory, HVAC, manufacturing, and power electronics applications benefit from this diode’s high surge capacitance and reliable voltage clamping under extreme conditions. The device ensures a safer margin for protecting sensitive circuits from voltage spikes, thereby extending component lifetime and ensuring stable operation.
