Overview
BZD27B7V5P-HE3_A18 from Vishay Semiconductors is an AEC-Q101-qualified unidirectional silicon planar Zener diode in DO-219AB (SMF) package, with nominal zener voltage 7.5 V ±2 % at 100 mA test current, dynamic resistance ≤2 Ω, and surge power rating of 150 W (10/1000 μs). It delivers stable voltage regulation and transient overvoltage protection in automotive power rail conditioning circuits.
For engineers reviewing the BZD27B7V5P-HE3_A18 datasheet, BZD27B7V5P-HE3_A18 pinout, BZD27B7V5P-HE3_A18 application, or BZD27B7V5P-HE3_A18 equivalent, key selection criteria include its 7.5 V clamping voltage at 13.3 A peak surge current, -65 °C to +175 °C operating range, MSL Level 1 reflow compatibility, and AEC-Q101 qualification for under-hood automotive use.
Technical Context
This device operates as a precision voltage reference and transient voltage suppressor in unidirectional configuration. Its low dynamic resistance (≤2 Ω) ensures tight regulation under load variation, while its 150 W non-repetitive peak surge power rating enables robust ESD and load-dump protection per ISO 7637-2.
The BZD27B7V5P-HE3_A18 features a temperature coefficient of 0 to +0.07 %/°C, enabling stable performance across automotive thermal extremes. Its DO-219AB package supports wave and reflow soldering with peak temperature up to 260 °C and meets JESD201 Class 2 whisker testing.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ7.5A-E3/52 | Higher clamping voltage (12.9 V), larger SMB package (4.5 × 3.9 mm), 600 W surge rating | Better suited for high-energy industrial surges; less precise regulation due to wider VC–VZ gap | Select when energy absorption >150 W is required and board space allows larger footprint |
| BZX84-C7V5-HE3-08 | Smaller SOT-23 package, ±5 % VZ tolerance, 300 mW power rating, no AEC-Q101 qualification | Limited to low-power consumer or non-automotive applications; unsuitable for under-hood thermal or reliability demands | Choose only for cost-sensitive, non-automotive designs where AEC-Q101 and 150 W surge are not required |
Compared with SMBJ7.5A-E3/52 and BZX84-C7V5-HE3-08, the BZD27B7V5P-HE3_A18 uniquely balances automotive-grade reliability (AEC-Q101, MSL 1, 175 °C TJ), precision regulation (±2 %, ≤2 Ω), and compact DO-219AB packaging-making it optimal for space-constrained, thermally demanding automotive voltage reference and clamping roles.
