Product details
Overview
BZD27B10P-HE3_A08 from Vishay Semiconductors is a surface-mount, AEC-Q101 qualified Zener diode with nominal breakdown voltage of 10 V (±2 %), 50 mA test current, 14.2 V clamping voltage at 10.1 A surge current, and 150 W peak surge power rating. It operates across -65 °C to +175 °C and is used for overvoltage protection in automotive power supply rails and ECU input conditioning.
For engineers reviewing the BZD27B10P-HE3_A08 datasheet, BZD27B10P-HE3_A08 pinout, BZD27B10P-HE3_A08 application, or BZD27B10P-HE3_A08 equivalent, key selection criteria include its ±2 % VZ tolerance, 150 W 10/1000 μs surge rating, DO-219AB (SMF) package compatibility, and AEC-Q101 qualification for automotive-grade transient suppression.
Technical Context
This unidirectional Zener diode functions as a precision voltage reference and transient voltage suppressor. Its 10 V nominal Zener voltage is specified at 50 mA with dynamic resistance of 7.5 Ω and temperature coefficient of +0.05 to +0.09 %/°C, enabling stable regulation under varying thermal conditions.
The device delivers 150 W non-repetitive peak surge power per IEC 60-1 (10/1000 μs waveform) and features low leakage current (≤20 μA at 8.2 V), 1.2 V forward voltage at 0.2 A, and MSL level 1 moisture sensitivity - all validated per J-STD-020 and JESD 201 Class 2 whisker testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10A | TVS diode with 10 V standoff, 17.5 V clamping at 10.3 A, 600 W peak power; higher clamping voltage, no Zener regulation function | Designed for high-energy surge suppression only; lacks precision voltage reference capability | Select SMBJ10A when primary need is high-power transient absorption rather than regulated voltage reference |
| BZX84-C10LT1G | SOT-23 Zener with 10 V nominal, ±5 % tolerance, 300 mW power, 100 mA test current; lower surge rating (40 W), no AEC-Q101 qualification | Targeted at consumer-grade low-power regulation; unsuitable for automotive or industrial surge environments | Select BZX84-C10LT1G only for cost-sensitive, non-automotive board-level voltage references with no surge exposure |
Compared with SMBJ10A and BZX84-C10LT1G, BZD27B10P-HE3_A08 uniquely combines ±2 % Zener tolerance, 150 W surge capability, and AEC-Q101 qualification - making it the only option suitable for automotive-grade voltage regulation *and* transient suppression in a single DO-219AB device.

The BZD27B10P-HE3_A08 has a Zener voltage range of 9.80 V to 10.20 V at 50 mA test current, corresponding to a tight ±2 % tolerance. This specification is guaranteed per the Vishay BZD27B Series datasheet Rev. 2.1 and enables accurate voltage referencing in automotive and industrial circuits where regulation stability is critical. The BZD27B10P-HE3_A08 achieves this tolerance without binning or post-manufacture sorting.
Does BZD27B10P-HE3_A08 support lead-free reflow soldering?
Yes, BZD27B10P-HE3_A08 is fully compatible with lead-free reflow soldering processes, rated for a maximum peak temperature of 260 °C per J-STD-020. Its DO-219AB (SMF) package meets MSL Level 1, eliminating the need for dry-packaging or baking prior to assembly. The BZD27B10P-HE3_A08 has been validated for wave and reflow soldering in accordance with Vishay's qualification standards.
What is the clamping voltage of BZD27B10P-HE3_A08 under surge conditions?
The BZD27B10P-HE3_A08 exhibits a clamping voltage (VC) of 14.2 V at 10.1 A peak surge current, measured using the 10/1000 μs waveform per IEC 60-1. This value is specified in the "Electrical Characteristics" table for protection-mode operation and defines the maximum voltage imposed on downstream circuitry during transient events. The BZD27B10P-HE3_A08 maintains this clamping performance across its full operating temperature range.
Is BZD27B10P-HE3_A08 qualified to AEC-Q101?
Yes, BZD27B10P-HE3_A08 is explicitly AEC-Q101 qualified, as indicated by the "-HE3" suffix in its ordering code and confirmed in the Vishay BZD27B Series datasheet. This qualification covers stress tests including HTGB, HTRB, TST, and ESD (HBM >8 kV, MM >800 V), validating its suitability for automotive electronic control units. The BZD27B10P-HE3_A08 is not a commercial-grade variant - it is manufactured and tested to automotive reliability standards.
What package type does BZD27B10P-HE3_A08 use?
BZD27B10P-HE3_A08 uses the DO-219AB (SMF) package - a low-profile surface-mount outline measuring 2.7 mm × 3.5 mm with 1.2 mm height. Vishay documentation confirms mechanical compatibility with SOD-123W, SOD-123F, and SOD-123FL footprints, though the BZD27B10P-HE3_A08 is specifically molded in the SMF case. The cathode is marked by a band on the top surface, and orientation in tape follows standard SMF carrier specifications.
