Product details
Overview
SMBJ36AHE3_B/I from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed to protect sensitive electronics against voltage transients induced by inductive load switching and lightning surges. It features a 36 V stand-off voltage (VWM), 40.0–44.2 V breakdown voltage (VBR) at 1 mA, 58.1 V maximum clamping voltage (VC) at 10.3 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform.
For engineers reviewing the SMBJ36AHE3_B/I datasheet, SMBJ36AHE3_B/I pinout, SMBJ36AHE3_B/I application, or SMBJ36AHE3_B/I equivalent, this device is selected for robust overvoltage protection on DC power rails and signal lines in automotive, industrial, and telecom systems where AEC-Q101 qualification, low clamping ratio, and fast response time are critical.
Technical Context
This TVS diode operates as a unidirectional clamping device with cathode-banded polarity, leveraging a glass-passivated silicon junction for stable avalanche breakdown behavior. Its thermal resistance (RθJA = 100 °C/W) and junction temperature range (−55 °C to +150 °C) support reliable operation under repetitive surge conditions when mounted on 5.0 mm × 5.0 mm copper pads.
The SMBJ36AHE3_B/I delivers precise transient suppression with 1.0 µA max reverse leakage at VWM, 0.100 %/°C temperature coefficient of VBR, and meets MSL Level 1 per J-STD-020 with 260 °C lead-free reflow compatibility - confirming suitability for high-reliability automated SMT assembly.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36AHM3_B/I | Halogen-free variant with identical electrical specs and AEC-Q101 qualification. | No difference in circuit function or layout; used where halogen-free compliance is mandated. | Select when RoHS + halogen-free material declaration is required for end-product certification. |
| SMBJ36A-E3/5B | Commercial-grade (non-AEC-Q101), same VWM/VC/PPPM, packaged in 13" reel (3200 pcs). | Lacks automotive qualification; suitable for industrial or consumer applications with lower reliability requirements. | Choose for cost-sensitive non-automotive designs where AEC-Q101 is not mandated. |
Compared with SMBJ36AHE3_B/I, the HM3 variant adds halogen-free compliance without performance trade-offs, while the E3/5B offers identical protection performance at lower qualification level and different packaging - enabling selection based on regulatory and supply chain needs rather than electrical redesign.

FAQ
What is the clamping voltage of SMBJ36AHE3_B/I at its rated peak pulse current?
The SMBJ36AHE3_B/I has a maximum clamping voltage (VC) of 58.1 V at 10.3 A peak pulse current (IPPM) with a 10/1000 µs waveform. This value is measured under standard test conditions and defines the upper voltage limit imposed on protected circuits during surge events. The SMBJ36AHE3_B/I maintains this clamping performance across its full operating temperature range.
Is SMBJ36AHE3_B/I qualified for automotive use?
Yes, SMBJ36AHE3_B/I is AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "HE3" and documentation in datasheet 88392. This qualification covers stress tests including high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing - making SMBJ36AHE3_B/I suitable for under-hood and chassis-mounted automotive modules.
What is the reverse leakage current specification for SMBJ36AHE3_B/I at its stand-off voltage?
The SMBJ36AHE3_B/I specifies a maximum reverse leakage current (ID) of 1.0 µA at its 36 V stand-off voltage (VWM) and 25 °C ambient temperature. This low leakage ensures minimal power loss in always-on systems and preserves battery life in automotive and portable applications where SMBJ36AHE3_B/I is deployed.
Does SMBJ36AHE3_B/I have a defined thermal resistance value?
Yes, SMBJ36AHE3_B/I has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on the recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pad per terminal. This value is critical for estimating junction temperature rise under sustained power dissipation and must be applied with actual PCB copper area and airflow conditions in the final SMBJ36AHE3_B/I layout.
What package type does SMBJ36AHE3_B/I use, and is it compatible with standard SMT processes?
SMBJ36AHE3_B/I uses the SMB (DO-214AA) surface-mount package, with dimensions of 4.06 mm × 5.21 mm × 2.20 mm and matte tin-plated leads. It meets J-STD-002 and JESD 22-B102 solderability standards and is rated MSL Level 1 with 260 °C peak reflow profile - fully compatible with standard lead-free SMT assembly lines without pre-baking or special handling.
