Product details
Overview
BZD27B150P-HE3_A08 from Vishay Semiconductors is a surface-mount, AEC-Q101 qualified Zener diode with nominal breakdown voltage of 150 V, ±2 % tolerance, 5 mA test current, 201 V clamping voltage at 120 A surge, and 150 W peak surge power rating (10/1000 μs). It serves as a precision overvoltage protection device in automotive power rail conditioning circuits.
For engineers reviewing the BZD27B150P-HE3_A08 datasheet, BZD27B150P-HE3_A08 pinout, BZD27B150P-HE3_A08 application, or BZD27B150P-HE3_A08 equivalent, key selection criteria include its 150 V Zener voltage tolerance, 120 A surge current capability, DO-219AB (SMF) package compatibility, and AEC-Q101 qualification for automotive-grade transient suppression.
Technical Context
This unidirectional Zener diode operates in reverse-biased breakdown mode to regulate or clamp voltage transients. Its thermal resistance is 30 K/W junction-to-lead and 180 K/W junction-to-ambient (on 3 mm × 3 mm Cu pads), enabling robust surge handling up to 175 °C junction temperature.
The device features low leakage current (≤5 μA at VR = 120 V), dynamic impedance of 130 Ω at 5 mA, and a positive temperature coefficient of +0.09 to +0.13 %/°C - critical for stable clamping across automotive temperature ranges.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ150A-E3/52 | TVS diode (not Zener); 150 V standoff, 200 V clamping, 600 W peak power (10/1000 μs) | Higher surge capacity but looser voltage tolerance (±5 %); designed for fast transient suppression, not precision regulation | Select for higher-energy transients where clamping speed matters more than voltage accuracy |
| P6SMB150A | DO-214AA package; 150 V standoff, 201 V clamping, 600 W peak power; no AEC-Q101 qualification | Larger footprint (4.5 × 3.9 mm vs. 3.5 × 2.7 mm); lacks automotive qualification and MSL Level 1 rating | Choose for cost-sensitive industrial designs where automotive reliability and reflow compatibility are not required |
Compared with SMBJ150A-E3/52 and P6SMB150A, BZD27B150P-HE3_A08 offers tighter ±2 % voltage tolerance and AEC-Q101 qualification in a smaller DO-219AB package - making it optimal for space-constrained, automotive-grade overvoltage protection where precision clamping and long-term reliability are prioritized over raw surge wattage.
