Product details
Overview
TPSMC11AHE3_B/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for clamping voltage transients on power and signal lines. It features 11.0 V nominal breakdown voltage (VBR), 9.40 V stand-off voltage (VWM), 1500 W peak pulse power (10/1000 µs), 96.2 V maximum clamping voltage at 96.2 A peak pulse current, and operates up to +185 °C junction temperature.
For engineers reviewing the TPSMC11AHE3_B/H datasheet, TPSMC11AHE3_B/H pinout, TPSMC11AHE3_B/H application, or TPSMC11AHE3_B/H equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal derating behavior, and real-world protection use cases for automotive and industrial power rail hardening.
Technical Context
The TPSMC11AHE3_B/H uses passivated anisotropic rectifier technology optimized for high-temperature stability and low incremental surge resistance. Its unidirectional polarity enables robust forward conduction during overvoltage events while maintaining tight clamping under 10/1000 µs transients.
It is rated for 200 A non-repetitive forward surge current (8.3 ms half-sine), exhibits 0.067 %/°C temperature coefficient of VBR, and meets J-STD-020 MSL Level 1 with 260 °C reflow peak, confirming suitability for automated SMT assembly in demanding environments.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ11A | Lower PPPM (600 W), same VBR (11.0 V), SMB package (smaller footprint, lower thermal mass) | Limited to lower-energy transients; unsuitable for automotive load dump or industrial motor drive coupling | Select when space-constrained and surge energy remains below 600 W per event |
| TPSMC11AHM3_B/H | Identical electrical specs; HM3 suffix denotes halogen-free construction (vs. HE3's RoHS-only) | No functional difference; required only where halogen-free compliance is mandated by OEM or regional regulation | Choose HM3 if halogen-free material declaration is contractually required |
Compared with SMBJ11A and TPSMC11AHM3_B/H, the TPSMC11AHE3_B/H delivers 2.5× higher surge power handling in the same SMC footprint and satisfies AEC-Q101 without requiring halogen-free certification-making it optimal for cost-sensitive, high-reliability 12 V automotive power domains.

FAQ
What is the maximum clamping voltage of the TPSMC11AHE3_B/H at its rated peak pulse current?
The TPSMC11AHE3_B/H has a maximum clamping voltage (VC) of 15.6 V when subjected to its peak pulse current (IPPM) of 96.2 A under a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and ensures that downstream 12 V logic and power ICs remain within safe operating voltage limits during surge events. The TPSMC11AHE3_B/H maintains this clamping performance across its full operating temperature range.
Is the TPSMC11AHE3_B/H qualified for automotive applications?
Yes, the TPSMC11AHE3_B/H is AEC-Q101 qualified, as confirmed in the official Vishay datasheet (Document Number: 88407, Revision: 19-Jan-2024). This qualification covers stress tests including high-temperature reverse bias (HTRB), high-temperature gate bias (HTGB), and temperature cycling (TCT), validating its reliability for use in automotive ECUs, body control modules, and ADAS sensor systems. The HE3 suffix explicitly denotes AEC-Q101 qualification.
What does the "HE3" suffix mean in TPSMC11AHE3_B/H?
The "HE3" suffix in TPSMC11AHE3_B/H indicates RoHS-compliant construction and AEC-Q101 qualification. Per Vishay's ordering nomenclature, base P/NHE3_X denotes devices meeting both environmental and automotive reliability standards. The "B/H" denotes packaging: 7-inch tape-and-reel with 850 units per reel. The TPSMC11AHE3_B/H is not halogen-free; for halogen-free compliance, the HM3 variant (e.g., TPSMC11AHM3_B/H) must be selected.
What is the thermal derating behavior of the TPSMC11AHE3_B/H above 25 °C ambient?
The TPSMC11AHE3_B/H follows standard derating curves per Figure 2 in the Vishay datasheet: peak pulse power decreases linearly from 100% at 25 °C to ~50% at 125 °C ambient, with full capability retained up to +185 °C junction temperature. Derating is based on initial junction temperature, not ambient alone. For sustained high-temperature operation, PCB copper pad area (minimum 8.0 mm × 8.0 mm per terminal) must be maintained to ensure thermal resistance stays within specification.
Can the TPSMC11AHE3_B/H replace the SMAJ11A in an existing design?
No, the TPSMC11AHE3_B/H is not a direct replacement for SMAJ11A due to package and power differences: SMAJ11A uses SMA (DO-214AC) package with 400 W PPPM, while TPSMC11AHE3_B/H uses larger SMC (DO-214AB) package with 1500 W PPPM. PCB layout, thermal pad size, and surge energy requirements differ significantly. Migration requires validation of board space, thermal relief, and clamping performance under actual system-level transients. The TPSMC11AHE3_B/H offers superior protection but demands mechanical redesign.
