Product details
Overview
BZD27B10P-HE3_A18 from Vishay Semiconductors is an AEC-Q101-qualified unidirectional silicon planar Zener diode in DO-219AB (SMF) package, rated for 10 V nominal Zener voltage (9.80–10.20 V), 50 mA test current, and 150 W non-repetitive peak surge power (10/1000 μs). It delivers low dynamic resistance (7.5 Ω typ.), tight ±2 % voltage tolerance, and operates across –65 °C to +175 °C for automotive power rail clamping.
For engineers reviewing the BZD27B10P-HE3_A18 datasheet, BZD27B10P-HE3_A18 pinout, BZD27B10P-HE3_A18 application, or BZD27B10P-HE3_A18 equivalent, key selection criteria include its 14.2 V clamping voltage at 10.1 A surge current, MSL Level 1 reflow compatibility, and AEC-Q101 qualification for under-hood electronics.
Technical Context
This Zener diode functions as a precision voltage reference and transient voltage suppressor in unidirectional configuration. Its design integrates low leakage current (<7 μA at 8.2 V), stable temperature coefficient (+0.05 to +0.09 %/°C), and robust surge capability per IEC 60-1 (10/1000 μs waveform).
The device uses silicon planar junction technology with metallized cathode marking and is optimized for wave and reflow soldering. Thermal performance is defined by RthJA = 180 K/W (on 3 mm × 3 mm Cu pads) and RthJL = 30 K/W, supporting high-power pulse handling up to 175 °C junction temperature.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10A | TVS diode, 10 V standoff, 16.7 V clamping at 10.1 A, higher capacitance (~100 pF) | Designed for faster transient suppression (sub-ns response); not a precision voltage reference | Select when surge speed dominates over DC regulation stability |
| BZX84-C10 | SOT-23 Zener, 10 V, ±5 % tolerance, 300 mW PD, no AEC-Q101 qualification | Limited to low-power consumer applications; lacks automotive surge rating and temperature range | Select only for cost-sensitive non-automotive designs with <100 mA continuous current |
Compared with SMBJ10A and BZX84-C10, BZD27B10P-HE3_A18 uniquely combines AEC-Q101 qualification, ±2 % voltage tolerance, and 150 W surge capability in a thermally efficient DO-219AB package-making it the only option qualified for under-hood 12 V rail protection where precision, reliability, and pulse handling are jointly required.

FAQ
What is the maximum clamping voltage of BZD27B10P-HE3_A18 under surge conditions?
The BZD27B10P-HE3_A18 clamps to 14.2 V at 10.1 A peak current under 10/1000 μs waveform conditions, as specified in the electrical characteristics table. This value is measured at TA = 25 °C and defines the upper voltage limit imposed on protected circuits during load dump or inductive switching events. The clamping behavior remains consistent across its –65 °C to +175 °C operating range due to its stable temperature coefficient.
Is BZD27B10P-HE3_A18 compatible with lead-free reflow soldering processes?
Yes, BZD27B10P-HE3_A18 is fully compatible with lead-free reflow soldering, rated for peak temperatures up to 260 °C per J-STD-020 MSL Level 1. Its DO-219AB package uses UL 94 V-0 molding compound and passes whisker testing per JESD 201 Class 2. No pre-bake is required prior to reflow, simplifying manufacturing flow for high-volume automotive PCB assembly.
How does the Zener voltage tolerance of BZD27B10P-HE3_A18 compare to standard Zener diodes?
BZD27B10P-HE3_A18 offers ±2 % Zener voltage tolerance at 10 V nominal, tighter than standard commercial Zeners (typically ±5 %). This is achieved via precision silicon planar processing and post-trim testing. The narrow tolerance reduces design margin requirements in voltage-reference and overvoltage-detection circuits, allowing direct replacement of binned parts in automotive control modules.
Can BZD27B10P-HE3_A18 be used in bidirectional transient suppression applications?
No, BZD27B10P-HE3_A18 is a unidirectional Zener diode and is not rated for reverse conduction beyond its specified clamping behavior. For bidirectional protection (e.g., RS-485 or USB lines), a dedicated bidirectional TVS like SMAJ10A or a back-to-back Zener pair would be required. Using BZD27B10P-HE3_A18 in reverse-biased AC signal paths risks parametric shift or failure.
What is the thermal resistance from junction to ambient for BZD27B10P-HE3_A18?
The junction-to-ambient thermal resistance (RthJA) of BZD27B10P-HE3_A18 is 180 K/W when mounted on a standard epoxy-glass PCB with 3 mm × 3 mm copper pads ≥40 μm thick. This value supports continuous power dissipation up to 800 mW at TA = 30 °C and enables reliable operation in sealed enclosures without forced airflow, such as in transmission control units.
