BZD27C27P-M3-08

The BZD27C27P-M3-08 is a silicon planar Zener diode from Vishay Dale's BZD27-M series, designed for voltage regulation and protection applications. It provides a nominal Zener voltage of 27V with a maximum impedance of 15Ω at a test current of 25mA. The device is rated for 800mW power dissipation at 30°C ambient temperature, with a higher 2300mW rating at 105°C lead temperature.

This diode features low reverse leakage current of 1µA maximum at 20V reverse voltage, and a forward voltage of 1.2V maximum at 200mA. It can handle non-repetitive peak surge power of 150W with a 10/1000µs waveform and 300W with a 100µs square pulse, making it suitable for transient voltage suppression in sensitive circuits.

The device is packaged in a DO-219AB (SMF) surface mount package weighing 15mg, with UL 94 V-0 flammability rating and MSL level 1 moisture sensitivity. It is RoHS3 compliant, halogen-free, and AEC-Q101 qualified for automotive applications. The operating temperature range spans from -65°C to 175°C, with junction-to-lead thermal resistance of 30K/W and junction-to-ambient thermal resistance of 180K/W when mounted on standard PCB.

This Zener diode is suitable for voltage clamping, reference voltage generation, and overvoltage protection in power supplies, automotive electronics, and industrial control systems. Its surface mount package enables automated assembly and space-efficient PCB layouts.
