Product details
Overview
TPSMB11AHE3_A/H from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor (TVS) designed for clamping inductive switching surges and lightning-induced transients on power rails and signal lines. It features a 11.0 V nominal breakdown voltage (VBR), 9.4 V stand-off voltage (VWM), 600 W peak pulse power (10/1000 µs), 15.6 V maximum clamping voltage at 38.5 A, and operates up to +185 °C junction temperature - used in automotive power supply protection and industrial sensor interface circuits.
For engineers reviewing the TPSMB11AHE3_A/H datasheet, TPSMB11AHE3_A/H pinout, TPSMB11AHE3_A/H application, or TPSMB11AHE3_A/H equivalent, key selection criteria include unidirectional polarity, SMB (DO-214AA) package compatibility, AEC-Q101 qualification status, TJ = 185 °C rating, and clamping performance under 10/1000 µs surge conditions.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology with optimized junction passivation for stable high-temperature operation. Its unidirectional architecture provides low incremental surge resistance and fast response time (<1 ns), enabling effective suppression of repetitive transients in automotive and industrial environments where thermal derating above 25 °C must be considered per Fig. 2.
The device is rated for 75 A non-repetitive forward surge current (8.3 ms half-sine) and exhibits a typical VBR temperature coefficient of +0.067 %/°C. It meets MSL Level 1 per J-STD-020 with 260 °C reflow peak and is RoHS-compliant with matte tin-plated leads solderable per J-STD-002.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ11A | Same SMB package, identical VBR (10.5–11.6 V), but rated for 600 W with 10/1000 µs waveform and no AEC-Q101 qualification | Not qualified for automotive use; suitable for industrial/commercial designs without automotive reliability requirements | Select SMBJ11A when AEC-Q101 is not mandated and cost optimization is prioritized |
| TPSMB11AHM3_A/H | Identical electrical specs and AEC-Q101 qualification; differs only in halogen-free molding compound (HM3 vs HE3) | Required for RoHS-compliant, halogen-free BOMs in EU automotive programs (e.g., VW TL 813) | Choose TPSMB11AHM3_A/H when halogen-free compliance is mandatory per customer specification |

FAQ
What is the breakdown voltage tolerance for TPSMB11AHE3_A/H?
The TPSMB11AHE3_A/H has a guaranteed breakdown voltage range of 10.5 V (minimum) to 11.6 V (maximum) at 1 mA test current, with a nominal value of 11.0 V. This ±5% tolerance ensures predictable clamping onset across production lots and temperature extremes up to +185 °C junction temperature.
Is TPSMB11AHE3_A/H qualified for automotive applications?
Yes, TPSMB11AHE3_A/H is AEC-Q101 qualified and designated for automotive use with the "HE3" suffix indicating RoHS-compliance and automotive qualification. It undergoes stress testing including HTGB, H3TRB, and temperature cycling per AEC-Q101 Rev G, supporting deployment in engine control, body electronics, and ADAS subsystems.
What is the maximum clamping voltage of TPSMB11AHE3_A/H at its rated peak pulse current?
The maximum clamping voltage (VC) of TPSMB11AHE3_A/H is 15.6 V at its rated peak pulse current (IPPM) of 38.5 A, measured using the 10/1000 µs waveform. This value is specified at TA = 25 °C and defines the upper voltage limit imposed on protected circuitry during worst-case transient events.
Does TPSMB11AHE3_A/H have a bidirectional configuration option?
No, TPSMB11AHE3_A/H is unidirectional only, as confirmed in the Vishay datasheet revision 23-Jan-2024. Bidirectional variants are not offered in the TPSMBxxA family; for bidirectional protection, engineers should consider the TPSMBxxCA series or alternate families such as SMAJ or SMCJ with "C" suffix.
What is the thermal derating behavior of TPSMB11AHE3_A/H above 25 °C ambient?
TPSMB11AHE3_A/H follows the derating curve in Figure 2 of the datasheet: peak pulse power decreases linearly from 100 % at 25 °C to ~50 % at 125 °C ambient, based on mounting on 0.2" × 0.2" copper pads. Designers must apply this curve when calculating safe surge margins in high-temperature enclosures or under-hood automotive locations.
