Product details
Overview
SMB10J22AHE3_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 with 1000 W peak pulse power (10/1000 µs), 22 V stand-off voltage (VWM), and 35.5 V clamping voltage (VC) at 28.2 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 SMB10J22AHE3_B/H datasheet, SMB10J22AHE3_B/H pinout, SMB10J22AHE3_B/H application, or SMB10J22AHE3_B/H equivalent, key selection criteria include unidirectional polarity, 22 V working voltage, 1000 W surge rating, AEC-Q101 qualification, and SMB package compatibility with automated SMT placement.
Technical Context
This TVS diode operates as a clamping device that remains high-impedance below VWM = 22 V and rapidly transitions to low-impedance conduction above its breakdown voltage (VBR = 24.4–26.9 V at 1 mA), limiting transient voltages to ≤35.5 V during 10/1000 µs surges up to 28.2 A. Its glass-passivated junction ensures stable performance under repetitive stress.
Designed for surface-mount use on PCBs with minimum 0.2" × 0.2" copper pads per terminal, it features MSL Level 1 moisture sensitivity, matte tin-plated leads compliant with J-STD-002, and thermal resistance RθJA = 72 °C/W - enabling reliable operation up to TJ = 150 °C in automotive and industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 22 V - maximum continuous reverse operating voltage before clamping begins |
| VBR (min/max) | 24.4 V / 26.9 V at 1 mA - precise breakdown threshold defining turn-on sensitivity |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ22A-E3/52 | Same VWM (22 V), identical SMB package, but rated for 600 W PPPM and not AEC-Q101 qualified | Commercial-grade only; unsuitable for automotive under-hood use due to missing qualification and lower surge rating | Select SMB10J22AHE3_B/H when AEC-Q101 compliance and 1000 W surge handling are required |
| SMCJ22AHE3_A/H | Higher PPPM (1500 W), same VWM and VC, but larger SMC (DO-214AB) package (7.11 mm × 6.22 mm) | Requires PCB layout change; better for extreme surge environments but increases board area by ~2.5× | Choose SMB10J22AHE3_B/H where space-constrained SMB footprint and automotive qualification are mandatory |
Compared with SMBJ22A-E3/52 and SMCJ22AHE3_A/H, SMB10J22AHE3_B/H uniquely balances AEC-Q101 qualification, 1000 W surge rating, and compact SMB footprint - making it optimal for space-limited automotive modules requiring certified reliability.

FAQ
What is the clamping voltage of SMB10J22AHE3_B/H at its rated peak pulse current?
The SMB10J22AHE3_B/H has a maximum clamping voltage (VC) of 35.5 V at its rated peak pulse current (IPPM) of 28.2 A, measured under the standardized 10/1000 µs waveform. This value ensures protected circuits remain below critical voltage thresholds during surge events, and is confirmed in Vishay Document Number 88422, page 2, unidirectional electrical characteristics table.
Is SMB10J22AHE3_B/H suitable for automotive applications?
Yes, SMB10J22AHE3_B/H is AEC-Q101 qualified and explicitly designated for automotive use with the "HE3" suffix indicating RoHS-compliant and AEC-Q101-qualified construction. It meets requirements for under-hood and body electronics, including ISO 7637-2 and ISO 16750-2 transient immunity, and is referenced in Vishay's ordering information table for automotive-grade variants.
What is the standoff voltage (VWM) and why is it important for SMB10J22AHE3_B/H?
The standoff voltage (VWM) of SMB10J22AHE3_B/H is 22 V - the maximum DC or continuous reverse voltage the device can withstand without entering breakdown. This parameter ensures normal circuit operation without leakage or conduction during steady-state conditions, while allowing rapid clamping above this threshold during transients. It is specified in the unidirectional electrical characteristics table of Vishay Document 88422.
Does SMB10J22AHE3_B/H have polarity markings, and how is it oriented on the PCB?
Yes, SMB10J22AHE3_B/H is unidirectional and features a cathode band marking on the SMB (DO-214AA) package body. During PCB layout, the banded end must be connected to ground or the reference rail, while the anode connects to the line being protected. This orientation ensures correct clamping direction and is documented in the mechanical data section of Vishay Document 88422, page 5.
What is the peak pulse power rating of SMB10J22AHE3_B/H and under what test condition is it defined?
The SMB10J22AHE3_B/H has a peak pulse power rating (PPPM) of 1000 W, defined under the industry-standard 10/1000 µs double-exponential current waveform per ANSI/IEEE C62.35. This rating reflects its ability to absorb high-energy transients without failure when mounted on 0.2" × 0.2" copper pads per terminal, as specified in Vishay Document 88422, page 1 (maximum ratings table).
