Product details
Overview
TPSMC22HE3_A/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for high-reliability overvoltage protection of sensitive electronics. It features 22 V breakdown voltage (VBR = 20.9–23.1 V at 1 mA), 18.8 V stand-off voltage (VWM), 30.6 V clamping voltage (VC) at 49 A peak pulse current, and 1500 W peak pulse power rating with 10/1000 μs waveform - deployed on automotive sensor signal lines, industrial I/O ports, and MOSFET gate drivers.
For engineers reviewing the TPSMC22HE3_A/H datasheet, TPSMC22HE3_A/H pinout, TPSMC22HE3_A/H application, or TPSMC22HE3_A/H equivalent, key selection criteria include its AEC-Q101 qualification, TJ = 185 °C maximum junction temperature, unidirectional polarity, low incremental surge resistance, and MSL Level 1 moisture sensitivity rating.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to deliver stable clamping under repetitive transients while maintaining low leakage (<1 μA at VWM) and fast response time (<1 ns). Its thermal design supports operation up to +185 °C junction temperature, enabling use in under-hood automotive environments and high-temperature industrial control units.
The device is rated for 200 A non-repetitive forward surge current (IFSM, 8.3 ms half-sine) and exhibits a positive temperature coefficient of VBR (+0.084 %/°C), ensuring predictable voltage shift across temperature extremes without requiring external compensation.

Use Value: 1500 W rating and 30.6 V clamping ensure compliance with GR-1089-CORE Level 3 requirements without sacrificing efficiency. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ22A | Lower PPPM (600 W), same VBR range, SMB package (smaller footprint, lower thermal mass) | Not AEC-Q101 qualified; limited to commercial/industrial ambient (TJ max = 150 °C) | Select when board space is constrained and automotive qualification is not required. |
| TPSMC22AHM3_A/H | Identical electrical specs; halogen-free molding compound and whisker-tested terminations | Same automotive qualification but meets stricter material compliance (halogen-free, JESD201 Class 2) | Choose for RoHS+halogen-free programs requiring full material declaration and whisker resistance. |
Compared with SMBJ22A and TPSMC22AHM3_A/H, the TPSMC22HE3_A/H provides the optimal balance of AEC-Q101 qualification, 1500 W surge capacity, and industry-standard RoHS compliance - making it preferred for Tier-1 automotive subsystems where both reliability and supply-chain traceability are mandated.

FAQ
What is the clamping voltage of the TPSMC22HE3_A/H at its rated peak pulse current?
The TPSMC22HE3_A/H has a maximum clamping voltage (VC) of 30.6 V at 49 A peak pulse current (IPPM) under the standard 10/1000 μs waveform. This value ensures downstream components like microcontrollers or transceivers remain within safe operating voltage limits during surge events. The clamping performance is validated per ANSI/IEEE C62.35 and confirmed in Vishay's datasheet Figure 5. The TPSMC22HE3_A/H maintains this specification across its full operating temperature range.
Is the TPSMC22HE3_A/H qualified for automotive applications?
Yes, the TPSMC22HE3_A/H is AEC-Q101 qualified, as explicitly stated in the Vishay datasheet (Document Number: 88407, Revision: 19-Jan-2024). It undergoes rigorous stress testing including temperature cycling, high-temperature reverse bias (HTRB), and ESD per JS-001. The "HE3" suffix denotes RoHS-compliant, AEC-Q101-qualified construction. This makes the TPSMC22HE3_A/H suitable for use in engine control units, ADAS sensors, and body electronics where automotive-grade reliability is mandatory.
What is the package type and mounting configuration of the TPSMC22HE3_A/H?
The TPSMC22HE3_A/H uses the SMC (DO-214AB) surface-mount package, with cathode identified by a color band. Its mechanical outline matches JEDEC DO-214AB standards, featuring 0.305" × 0.220" body dimensions and matte tin-plated leads compliant with J-STD-002 and JESD 22-B102. The device is designed for reflow soldering on 8.0 mm × 8.0 mm copper pads per terminal and meets MSL Level 1 per J-STD-020 - confirming zero floor life restriction and compatibility with standard lead-free reflow profiles peaking at 260 °C.
How does the TPSMC22HE3_A/H differ from the TPSMC22AHM3_A/H variant?
The TPSMC22HE3_A/H and TPSMC22AHM3_A/H share identical electrical specifications and AEC-Q101 qualification, but differ in material composition: the HM3 version uses halogen-free molding compound and meets JESD201 Class 2 whisker resistance requirements, while the HE3 version is RoHS-compliant with standard flame-retardant epoxy (UL 94 V-0). Both are supplied in 7" tape-and-reel (850 pcs), but the HM3 variant is selected when full halogen-free compliance and enhanced metallurgical reliability are required for aerospace or medical-grade designs.
What is the maximum junction temperature rating for the TPSMC22HE3_A/H?
The TPSMC22HE3_A/H is rated for a maximum junction temperature (TJ) of +185 °C, as specified in the Vishay datasheet under "Maximum Ratings." This high-temperature capability enables reliable operation in under-hood automotive environments, near power converters, or in sealed industrial enclosures without thermal derating. The device's passivated anisotropic rectifier structure and optimized thermal path sustain stable VBR drift (αT = +0.084 %/°C) across this full range, ensuring predictable clamping behavior even at elevated ambient temperatures.
