Product details
Overview
SMB10J26AHE3_B/H from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for high-energy surge protection on DC power rails and signal lines. It features a 26 V stand-off voltage (VWM), 28.9–31.9 V breakdown voltage (VBR) at 1 mA, 42.1 V clamping voltage (VC) at 23.8 A peak pulse current (IPPM), and 1000 W peak pulse power (PPPM) with 10/1000 µs waveform - deployed in automotive power electronics and industrial sensor interfaces.
For engineers reviewing the SMB10J26AHE3_B/H datasheet, SMB10J26AHE3_B/H pinout, SMB10J26AHE3_B/H application, or SMB10J26AHE3_B/H equivalent, this device is selected for robust ESD and load-dump immunity in AEC-Q101-compliant systems where low clamping voltage, fast response (<1 ns), and MSL Level 1 reflow compatibility are critical.
Technical Context
This TVS diode operates as a unidirectional clamping device with avalanche breakdown behavior, optimized for transient suppression per ISO 7637-2 and IEC 61000-4-5 standards. Its glass-passivated junction ensures stable VBR tolerance and low leakage (<1 µA at 26 V), while the SMB package enables automated placement and thermal dissipation via 5.0 mm × 5.0 mm copper pads.
The device supports 150 °C maximum junction temperature and exhibits 72 °C/W junction-to-ambient thermal resistance. It is qualified to AEC-Q101 for automotive use and meets JESD201 Class 2 whisker resistance and UL 94 V-0 flammability requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 26 V - maximum continuous reverse operating voltage before clamping begins |
| VBR min/max | 28.9 V / 31.9 V at 1 mA - tight breakdown window ensures predictable turn-on during transients |
| VC @ IPPM | 42.1 V at 23.8 A - limits downstream voltage stress during 1000 W surge events |
| PPPM | 1000 W (10/1000 µs) - sustains high-energy surges common in automotive load-dump scenarios |
| ID @ VWM | <1 µA - minimal standby power loss and signal integrity impact in always-on circuits |
| TJ max | +150 °C - enables operation in under-hood automotive environments and industrial enclosures |
| Package | SMB (DO-214AA) - surface-mount footprint compatible with standard SMT assembly and IPC-7351B land patterns |
Pinout & Package
Two-terminal unidirectional TVS diode in SMB (DO-214AA) package: cathode marked by color band; anode and cathode terminals support bidirectional PCB layout routing with polarity-aware placement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point in forward bias; connected to protected line's lower-potential side | Defines reference node for clamping action - ties to GND or return path in unidirectional configuration |
| Cathode | Current exit point in forward bias; marked by color band; connected to protected line's higher-potential side | Clamps transients toward ground when voltage exceeds VBR - determines directionality and circuit integration logic |
Key Features

| AEC-Q101 qualification | Validated for automotive powertrain and body electronics per stress test requirements including temperature cycling and HTRB |
| MSL Level 1 rating | Supports lead-free reflow up to 260 °C peak without moisture-induced damage - no baking required pre-assembly |
| Glass-passivated junction | Ensures long-term VBR stability and low parameter drift across 1000+ hours of HTOL testing |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (e.g., ISO 16750-2 pulse 5a), improving system-level robustness |
| UL 94 V-0 molding compound | Meets flame-retardancy requirements for enclosed automotive modules and industrial control cabinets |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ26AHE3_A/H | Same VWM (26 V), identical SMB package, but lower PPPM (600 W) and higher VC (42.8 V at 15.2 A) | Suitable for lower-energy transients (e.g., IEC 61000-4-2 ESD only); not recommended for ISO 7637-2 load dump | Select SMB10J26AHE3_B/H when 1000 W surge handling and tighter VC margin are required. |

FAQ
What is the clamping voltage of SMB10J26AHE3_B/H at its rated peak pulse current?
The SMB10J26AHE3_B/H has a maximum clamping voltage (VC) of 42.1 V at 23.8 A peak pulse current (IPPM), measured under standardized 10/1000 µs waveform conditions. This value defines the upper voltage limit imposed on protected circuitry during a full-rated 1000 W transient event, ensuring downstream components remain within safe operating voltage margins.
Is SMB10J26AHE3_B/H qualified for automotive applications?
Yes, SMB10J26AHE3_B/H is AEC-Q101 qualified and carries the "HE3" suffix denoting RoHS-compliant, automotive-grade construction. It undergoes rigorous stress testing including temperature cycling, highly accelerated life testing (HALT), and humidity bias HTRB - validating suitability for engine control, lighting, and body electronics modules.
What is the standoff voltage (VWM) and why does it matter for SMB10J26AHE3_B/H?
The standoff voltage (VWM) of SMB10J26AHE3_B/H is 26 V - the maximum continuous reverse voltage the device can block without entering breakdown. This parameter ensures reliable operation under nominal 24 V automotive or industrial supply rails while maintaining sub-1 µA leakage, preserving efficiency and signal fidelity in always-on systems.
Does SMB10J26AHE3_B/H have a defined polarity, and how is it identified?
Yes, SMB10J26AHE3_B/H is a unidirectional TVS diode with defined polarity: the cathode is marked by a visible color band on the SMB package body. During PCB layout, the banded end must connect toward the higher-potential side (e.g., VBUS or signal line), while the anode connects to ground or return - reversing polarity disables clamping functionality.
What package type and mounting specifications apply to SMB10J26AHE3_B/H?
SMB10J26AHE3_B/H uses the SMB (DO-214AA) surface-mount package with matte tin-plated leads compliant with J-STD-002 and JESD22-B102 solderability standards. Recommended mounting uses 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal to achieve specified thermal resistance (RθJA = 72 °C/W) and 1000 W pulse power rating.
