Additional Details:

The 1.5SMCJ91A comes in an SMC (DO-214AB) package, which is designed for surface mounting on printed circuit boards. The operating junction temperature range is from -55°C to +150°C. The device is specifically designed to protect circuits operating at or near 91V. It’s unidirectional, meaning it provides protection only for positive polarity voltage spikes. This TVS diode is suitable for a wide range of applications where reliable transient voltage protection is required.
