Overview
TPSMB36A-1BHE3_A/I from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor (TVS) diode designed for clamping inductive switching transients and ESD events on power rails and signal lines. It features a 36 V breakdown voltage (VBR), 30.8 V stand-off voltage (VWM), 600 W peak pulse power (10/1000 µs), 12 A peak pulse current (IPPM), and 49.9 V maximum clamping voltage (VC) - used in automotive sensor protection, industrial I/O interfaces, and DC power input stages.
For engineers reviewing the TPSMB36A-1BHE3_A/I datasheet, TPSMB36A-1BHE3_A/I pinout, TPSMB36A-1BHE3_A/I application, or TPSMB36A-1BHE3_A/I equivalent, this page delivers verified electrical parameters, SMB (DO-214AA) package details, AEC-Q101 qualification status, thermal derating curves, and direct alternative part comparisons for robust overvoltage protection design-in.
Technical Context
This TVS diode operates as a unidirectional clamping device with an anisotropic rectifier structure optimized for low incremental surge resistance and fast response (<1 ns). Its junction passivation enables stable operation up to TJ = 185 °C, supporting high-reliability automotive and industrial environments where thermal cycling and long-term surge endurance are critical.
The device complies with JEDEC J-STD-020 MSL Level 1 (260 °C reflow peak), uses matte tin-plated leads per JESD 22-B102, and meets AEC-Q101 stress testing requirements - confirmed by the HE3 suffix indicating RoHS-compliant, AEC-Q101 qualified construction with JESD 201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 34.2 / 36.0 / 37.8 V - defines precise clamping onset threshold at 1 mA test current; ensures reliable turn-on before downstream IC damage. |
| VWM | 30.8 V - maximum continuous reverse operating voltage; must exceed system nominal rail (e.g., 24 V DC bus) to prevent leakage conduction. |
| VC @ IPPM | 49.9 V - clamped voltage during 12 A 10/1000 µs surge; determines worst-case overvoltage seen by protected circuitry. |
| PPPM | 600 W - peak pulse power handling under standard 10/1000 µs waveform; validates immunity to IEC 61000-4-5 Level 4 surges. |
| IFSM | 75 A - non-repetitive forward surge rating (8.3 ms half-sine); supports protection against load dump events in 12 V/24 V automotive systems. |
| TJ max. | +185 °C - maximum junction temperature; enables use in under-hood or enclosed industrial enclosures without thermal derating penalties. |
Pinout & Package
Package: SMB (DO-214AA) - surface-mount plastic case with cathode band marking; 0.220" × 0.130" footprint; UL 94 V-0 rated molding compound; compatible with standard reflow profiles (MSL Level 1, 260 °C peak).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction or clamping | Connected to lower-potential side of protected line (e.g., GND or return path); forms low-impedance shunt to ground during overvoltage. |
| Cathode | Current exit point during clamping; marked with color band | Connected to higher-potential side (e.g., +24 V rail or signal line); reverse-biased under normal operation; avalanches when VAK > VBR. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and surge lifetime testing - required for engine control, ADAS, and body electronics. |
| 185 °C junction rating | Enables uninterrupted operation in high-ambient environments (e.g., near power converters or motor drivers) without derating below full surge capability. |
| Low clamping ratio (VC/VBR ≈ 1.39) | Minimizes overvoltage margin between clamping and breakdown - improves protection margin for 3.3 V/5 V logic and 24 V microcontrollers. |
| Fast response time (<1 ns) | Responds before ESD or lightning-induced transients propagate through PCB traces - essential for protecting high-speed sensor interfaces and CAN transceivers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36A | Same SMB package, identical VBR/VC specs, but not AEC-Q101 qualified; MSL Level 1 only; no whisker test certification. | Lacks automotive qualification - suitable for industrial/commercial designs where AEC-Q101 is not mandated. | Select SMBJ36A only if automotive reliability testing is unnecessary and cost sensitivity outweighs long-term field failure risk. |
| TPSMB36AHM3_A/I | Identical electrical specs and AEC-Q101 qualification; differs only in halogen-free molding compound (HM3 vs HE3). | Required for RoHS + halogen-free compliance mandates (e.g., EU automotive Tier 1 supply chains). | Choose TPSMB36AHM3_A/I when material compliance (IEC 61249-2-21) is contractually enforced, otherwise TPSMB36A-1BHE3_A/I remains fully functionally equivalent. |
Compared with SMBJ36A and TPSMB36AHM3_A/I, the TPSMB36A-1BHE3_A/I provides AEC-Q101 qualification and JESD 201 Class 2 whisker resistance in a RoHS-compliant package - making it the preferred choice for automotive and high-reliability industrial deployments where long-term solder joint integrity and stress validation are mandatory.
