Overview
BZD27B13P-HE3_A18 from Vishay Semiconductors is a surface-mount, AEC-Q101-qualified Zener diode with nominal breakdown voltage of 13 V (±2 %), 50 mA test current, 17.8 V clamping voltage at 7.9 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 rails and industrial sensor interfaces.
For engineers reviewing the BZD27B13P-HE3_A18 datasheet, BZD27B13P-HE3_A18 pinout, BZD27B13P-HE3_A18 application, or BZD27B13P-HE3_A18 equivalent, key selection criteria include its ±2 % VZ tolerance, 150 W 10/1000 μs surge rating, low dynamic resistance (10 Ω), AEC-Q101 qualification, and DO-219AB (SMF) package compatibility.
Technical Context
This unidirectional Zener diode functions as a precision voltage reference and transient voltage suppressor. Its design supports stable regulation under DC bias and robust clamping during fast transients, with temperature coefficient of +0.05 to +0.1 %/°C and junction-to-lead thermal resistance of 30 K/W.
The device uses silicon planar construction and is optimized for wave and reflow soldering. It meets JESD201 Class 2 whisker testing, MSL Level 1 per J-STD-020, and delivers <1 μA reverse leakage at rated VR, enabling reliable operation in high-reliability automotive and industrial environments.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13A | TVS diode (not Zener-regulated); higher 200 W PPPM, but looser VBR tolerance (±5 %) | Better for high-energy ESD/surge; less suitable for precision voltage reference roles | Select when primary need is transient suppression only, not regulated DC bias. |
| BZT52B13S | SOD-323 package; same 13 V nominal, but only 200 mW Ptot, no AEC-Q101 qualification | Limited to low-power consumer electronics; unsuitable for automotive or industrial surge duty | Choose only for space-constrained non-automotive designs with <100 mA average current. |

FAQ
What is the Zener voltage tolerance of BZD27B13P-HE3_A18?
The BZD27B13P-HE3_A18 has a Zener voltage tolerance of ±2 %, with a nominal value of 13.0 V and a specified range of 12.74 V to 13.26 V at 50 mA test current. This tight tolerance is confirmed in the Vishay BZD27B Series datasheet Rev. 2.1 and enables precise voltage regulation in automotive and industrial applications where reference stability is critical. The BZD27B13P-HE3_A18 achieves this performance using silicon planar Zener technology with controlled doping profiles.
Is BZD27B13P-HE3_A18 qualified for automotive use?
Yes, BZD27B13P-HE3_A18 is AEC-Q101 qualified, as indicated by the "-HE3" suffix in its ordering code and explicitly stated in the Vishay datasheet. It passes stress tests including high-temperature operating life, temperature cycling, and mechanical shock per AEC-Q101 standards. This qualification makes BZD27B13P-HE3_A18 suitable for under-hood and chassis-mounted automotive electronics where reliability under thermal and vibration stress is mandatory.
What package does BZD27B13P-HE3_A18 use, and what are its key dimensions?
BZD27B13P-HE3_A18 uses the DO-219AB (SMF) surface-mount package, measuring 3.9 mm × 2.7 mm × 1.2 mm (L × W × H) with a cathode band marking. Its footprint matches SOD-123W layouts, and it features a 1.3 mm × 1.3 mm pad recommendation for reflow soldering. The package meets MSL Level 1 and supports peak reflow temperatures up to 260 °C, eliminating pre-bake requirements during PCB assembly.
What is the clamping voltage of BZD27B13P-HE3_A18 during surge events?
The clamping voltage (VC) of BZD27B13P-HE3_A18 is 17.8 V at a peak surge current (IRSM) of 7.9 A under the 10/1000 μs waveform, as specified in the Vishay datasheet Table on page 3. This value defines the maximum voltage imposed on protected circuitry during transient events and is critical for ensuring downstream components like microcontrollers and transceivers remain within safe operating limits. The BZD27B13P-HE3_A18 achieves this clamping performance while maintaining low dynamic resistance (10 Ω).
Does BZD27B13P-HE3_A18 have a specified temperature coefficient?
Yes, BZD27B13P-HE3_A18 has a temperature coefficient (αVZ) of +0.05 %/°C minimum to +0.1 %/°C maximum at 50 mA test current. This positive coefficient means its Zener voltage increases slightly with rising junction temperature-a characteristic that improves regulation stability in warm automotive environments where cold-start errors are more problematic than hot-operation drift. The coefficient is measured and guaranteed per the BZD27B Series datasheet Rev. 2.1.
