Product details
Overview
BZD27B110P-HE3_A18 from Vishay Semiconductors is an AEC-Q101 qualified, unidirectional silicon planar Zener diode in DO-219AB (SMF) package, rated for 110 V nominal Zener voltage at 5 mA test current, 145 V clamping voltage at 1 A surge current, and 150 W non-repetitive peak surge power, used for overvoltage protection in automotive power supply rails.
For engineers reviewing the BZD27B110P-HE3_A18 datasheet, BZD27B110P-HE3_A18 pinout, BZD27B110P-HE3_A18 application, or BZD27B110P-HE3_A18 equivalent, key selection criteria include its ±2 % Zener tolerance, -65 °C to +175 °C operating temperature range, MSL level 1 moisture sensitivity, and 0.09 %/°C temperature coefficient - critical for high-reliability transient suppression in engine control units and ADAS modules.
Technical Context
This device operates as a precision voltage reference and transient voltage suppressor, leveraging silicon planar junction technology with low leakage (<5 μA at VR = 91 V) and stable dynamic impedance (80 Ω at IZT = 5 mA). Its unidirectional polarity and single-diode configuration support standard cathode-anode placement in series-clamp or shunt-regulator topologies.
Designed for automotive-grade reliability, it meets AEC-Q101 qualification, JESD201 Class 2 whisker resistance, and ESD robustness (>8 kV HBM), with thermal performance defined by RthJA = 180 K/W on 3 mm × 3 mm Cu pads and RthJL = 30 K/W - enabling sustained operation up to TJ = 175 °C under pulsed surge conditions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110A-E3/52 (Vishay) | TVS diode, bidirectional, 110 V standoff, 17.1 A IPP, 600 W peak pulse power | Higher surge capacity but looser voltage tolerance (±5 %), no AEC-Q101 grade option | Prefer for higher-energy transients where ±5 % VWM is acceptable and bidirectional protection is needed |
| P6SMB110A (ON Semiconductor) | TVS diode, unidirectional, 110 V standoff, 16.7 A IPP, 600 W peak pulse power, AEC-Q101 qualified | Same package (DO-214AA/SMB), but 600 W vs. 150 W rating and higher clamping voltage (175 V) | Choose when higher surge immunity is required and PCB layout allows larger footprint; not drop-in due to different VBR/VC |
Compared with SMBJ110A-E3/52 and P6SMB110A, BZD27B110P-HE3_A18 offers tighter ±2 % Zener tolerance and lower clamping voltage (145 V vs. ≥175 V), making it preferable for precision voltage reference and low-overhead protection in space-constrained automotive modules where DO-219AB's 2.9 mm × 1.9 mm footprint is critical.
