Product details
Overview
BZD27B7V5P-HE3_A08 from Vishay Semiconductors is a surface-mount, AEC-Q101 qualified Zener diode with nominal breakdown voltage 7.5 V, ±2 % tolerance, 100 mA test current, and 150 W peak surge power rating (10/1000 μs). It operates across -65 °C to +175 °C and serves as a precision voltage reference or transient overvoltage protector in automotive power rails and industrial sensor interfaces.
For engineers reviewing the BZD27B7V5P-HE3_A08 datasheet, BZD27B7V5P-HE3_A08 pinout, BZD27B7V5P-HE3_A08 application, or BZD27B7V5P-HE3_A08 equivalent, key selection criteria include its 7.35–7.65 V Zener range, 13.3 V clamping voltage at 13.3 A, low 2 Ω dynamic resistance, AEC-Q101 qualification, and DO-219AB (SMF) package compatibility.
Technical Context
This unidirectional Zener diode uses silicon planar construction for stable voltage regulation under DC bias and fast transient suppression during surge events. Its thermal design supports junction temperatures up to 175 °C, with RthJA = 180 K/W on standard 3 mm × 3 mm Cu pads and RthJL = 30 K/W for lead-mounted dissipation.
It delivers 10.9 V clamping voltage at 13.3 A (10/1000 μs waveform), exhibits a temperature coefficient of 0 to +0.07 %/°C, and maintains ≤1500 μA reverse leakage at 6.2 V - enabling reliable operation in high-temperature automotive ECUs and industrial PLC I/O protection circuits.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ7.5A-E3/52 | TVS diode (not Zener); 7.5 V standoff, 12.9 V clamping at 13.3 A; higher capacitance (150 pF) | Designed for fast transient suppression only; lacks precision regulation capability | Select when primary need is ESD/surge clamping without DC voltage reference function |
| BZX84-C7V5-HE3-08 | SOT-23 Zener; same 7.5 V nominal, but only 300 mW Ptot, 30 W surge rating, not AEC-Q101 qualified | Restricted to low-power consumer or non-automotive industrial use | Select only for cost-sensitive, non-automotive applications where surge immunity and high-temp operation are not required |
Compared with SMBJ7.5A-E3/52 and BZX84-C7V5-HE3-08, the BZD27B7V5P-HE3_A08 uniquely combines AEC-Q101 qualification, 150 W surge capability, ±2 % VZ tolerance, and 175 °C operation - making it the sole choice for automotive-grade Zener regulation and clamping where both precision and ruggedness are mandatory.
