Overview

Pinout

The SMAJ15CA-TR is a bidirectional TVS diode designed for transient voltage suppression.
- Pin Count: 2 pins (standard DO-214AC/SMA package).
- Function: Protects circuits from voltage spikes by clamping transient voltages to a safe level (15V breakdown voltage). It operates bidirectionally, safeguarding against both positive and negative surges.
Key specs:
- Standoff Voltage (V_RWM): 15V
- Breakdown Voltage (V_BR): 16.7V (min)
- Peak Pulse Power: 400W (8/20µs waveform).
Commonly used in power lines, communication ports, and automotive systems for ESD/EMI protection.

Application

The SMAJ15CA-TR is a TVS diode designed for transient voltage suppression in various applications. Key areas include:
1. Electronics Protection – Safeguards sensitive circuits from voltage spikes in consumer electronics, industrial controls, and telecom equipment.
2. Automotive Systems – Protects against load-dump and ESD in infotainment, ECUs, and lighting systems.
3. Power Supplies – Shields AC/DC converters and DC power lines from surges.
4. Communication Devices – Ensures reliability in routers, modems, and network interfaces.
5. Medical Equipment – Guards against transients in diagnostic and monitoring devices.
Its bidirectional clamping (15V) makes it ideal for ESD and surge protection in low-voltage circuits.

Package

The SMAJ15CA-TR is a TVS diode in an SMA (DO-214AC) package, designed for surface-mount applications. It offers transient voltage suppression up to 15V and is commonly used for ESD protection. The package is compact, measuring approximately 4.5mm x 2.5mm, making it suitable for space-constrained PCBs. The "-TR" suffix indicates it comes on a tape-and-reel for automated assembly.
