Product details
Overview
SMB10J26AHE3_A/H from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for high-energy surge protection with 1000 W peak pulse power (10/1000 µs), 26 V stand-off voltage (VWM), and 42.1 V clamping voltage at 23.8 A peak pulse current. It is AEC-Q101 qualified and used to protect automotive sensor signal lines, MOSFET gates, and microcontroller I/O against inductive switching transients.
For engineers reviewing the SMB10J26AHE3_A/H datasheet, SMB10J26AHE3_A/H pinout, SMB10J26AHE3_A/H application, or SMB10J26AHE3_A/H equivalent, key selection criteria include clamping performance under 10/1000 µs surge, AEC-Q101 qualification status, unidirectional polarity, thermal resistance (RθJA = 72 °C/W), and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector, leveraging a glass-passivated silicon junction to achieve sub-nanosecond response time and low incremental surge resistance. Its breakdown voltage is specified at 28.9–31.9 V (min/max) with 1 mA test current, ensuring reliable triggering above system operating voltage while maintaining <1.0 µA reverse leakage at 26 V.
The device is rated for -55 °C to +150 °C junction temperature, meets MSL Level 1 per J-STD-020 (260 °C peak reflow), and uses matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards. Polarity is marked by a cathode band on the SMB package body.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ26A-E3/52 | Same VWM (26 V), same SMB package, but commercial-grade (non-AEC-Q101) and RoHS-compliant only | Lacks automotive qualification; suitable for industrial/commercial designs without AEC requirements | Select when AEC-Q101 is not mandated and cost sensitivity outweighs automotive validation needs |
| SMB10J26AHM3_A/H | Identical electrical specs and AEC-Q101 qualification, but halogen-free and RoHS-compliant per JEDEC J-STD-020 | Same automotive use cases; required where halogen-free material compliance is enforced (e.g., EU auto OEMs) | Choose when halogen-free content is mandatory per procurement specification or environmental policy |
Compared with SMB10J26AHE3_A/H, SMBJ26A-E3/52 offers identical clamping and packaging but lacks automotive qualification, while SMB10J26AHM3_A/H matches all specs and adds halogen-free compliance-making the HE3 version optimal for general AEC-Q101 applications and HM3 for stricter material mandates.

FAQ
What is the clamping voltage of SMB10J26AHE3_A/H at its rated peak pulse current?
The SMB10J26AHE3_A/H has a maximum clamping voltage (VC) of 42.1 V at its peak pulse current (IPPM) of 23.8 A, measured under the standardized 10/1000 µs waveform. This value ensures protected circuits remain within safe voltage limits during surge events. The SMB10J26AHE3_A/H datasheet confirms this parameter is guaranteed across temperature and production lots.
Is SMB10J26AHE3_A/H suitable for automotive applications?
Yes, SMB10J26AHE3_A/H is AEC-Q101 qualified and explicitly designated for automotive use with the "HE3" suffix indicating RoHS-compliant and AEC-Q101 qualified construction. It supports under-hood and cabin applications including sensor protection, body control modules, and infotainment power rails. The SMB10J26AHE3_A/H meets MSL Level 1 and operates from -55 °C to +150 °C.
What is the standoff voltage (VWM) and why does it matter for SMB10J26AHE3_A/H?
The standoff voltage (VWM) of SMB10J26AHE3_A/H is 26 V - the maximum DC or continuous reverse voltage the device can block without entering avalanche conduction. This parameter ensures the SMB10J26AHE3_A/H remains non-conductive during normal operation, avoiding leakage or power loss, while still triggering reliably during transients exceeding this threshold.
How does the SMB10J26AHE3_A/H package compare to SMA or SMC variants?
The SMB10J26AHE3_A/H uses the SMB (DO-214AA) package, measuring 4.57 mm × 3.94 mm × 2.20 mm - smaller than SMC (DO-214AB) but larger than SMA (DO-214AC). Its 72 °C/W junction-to-ambient thermal resistance balances power handling and board space. Unlike SMA, SMB supports higher PPPM (1000 W vs. 400 W for SMAJ26A), making SMB10J26AHE3_A/H appropriate for medium-energy surge scenarios.
What is the meaning of the "_A/H" suffix in SMB10J26AHE3_A/H?
The "_A/H" suffix in SMB10J26AHE3_A/H denotes the revision code ("A") and packaging configuration ("H" = 7" tape-and-reel, 750 units per reel). This aligns with Vishay's ordering nomenclature where "HE3" indicates AEC-Q101 qualification and RoHS compliance, and "_A/H" specifies manufacturing revision and delivery format. The SMB10J26AHE3_A/H part is fully traceable and conforms to JESD201 Class 2 whisker resistance.
