Product details
Overview
TPSMB36AHM3_A/H from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor (TVS) designed for clamping inductive and lightning-induced transients on power rails and signal lines. It features a 36 V breakdown voltage (VBR = 34.2–37.8 V), 30.8 V stand-off voltage (VWM), 600 W peak pulse power (10/1000 µs), 12 A peak pulse current (IPPM), and operates up to +185 °C junction temperature - suitable for automotive power rail protection in engine control units.
For engineers reviewing the TPSMB36AHM3_A/H datasheet, TPSMB36AHM3_A/H pinout, TPSMB36AHM3_A/H application, or TPSMB36AHM3_A/H equivalent, key selection criteria include its AEC-Q101 qualification, halogen-free RoHS-compliant HM3 suffix, SMB (DO-214AA) package, unidirectional polarity, and verified clamping performance at 49.9 V under 12 A surge.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to deliver stable clamping with low incremental surge resistance and excellent response time (<1 ns). Its thermal design supports continuous operation at TJ = 185 °C, meeting high-reliability automotive requirements where sustained ambient temperatures exceed 125 °C.
The device is rated for 75 A non-repetitive forward surge (8.3 ms half-sine), exhibits only 3.5 V max forward voltage at 50 A, and maintains MSL Level 1 moisture sensitivity with 260 °C reflow compatibility - enabling robust placement in automated SMT lines without preconditioning.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 34.2 V / 36.0 V / 37.8 V - ensures reliable turn-on above system nominal voltage while avoiding false triggering during normal operation |
| VWM | 30.8 V - maximum continuous reverse working voltage compatible with 24 V automotive systems with margin |
| IPPM (10/1000 µs) | 12 A - clamps transients up to 600 W without degradation under standard surge waveform |
| VC @ IPPM | 49.9 V - peak clamped voltage seen by protected IC/MOSFET during full-rated surge event |
| TJ max. | +185 °C - enables use in under-hood automotive locations without derating |
| Polarity | Unidirectional - protects against positive-going transients only; requires correct cathode orientation toward supply rail |
| Package | SMB (DO-214AA) - industry-standard 2-pin surface-mount outline with 5.0 mm × 5.0 mm copper pad requirement for thermal dissipation |
Pinout & Package
TPSMB36AHM3_A/H is housed in the SMB (DO-214AA) package: a rectangular, surface-mount plastic case with matte tin-plated leads, cathode indicated by a color band. Dimensions: 4.57 mm × 3.94 mm × 2.20 mm (L × W × H); weight: 0.096 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction or clamping | Connected to ground or low-side return path; must be routed with low-inductance trace for effective transient shunting |
| Cathode | Current exit point during reverse-biased clamping | Connected to protected line (e.g., 24 V rail); color band identifies this terminal for correct PCB orientation |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified (HM3 suffix) | Validated for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock per JESD22 standards |
| Halogen-free & RoHS-compliant | Meets automotive environmental compliance requirements and eliminates corrosive off-gassing during reflow or field operation |
| MSL Level 1 (260 °C peak) | Supports standard lead-free reflow profiles without baking or special handling prior to assembly |
| 185 °C junction rating | Enables direct placement near heat sources (e.g., power MOSFETs, DC/DC converters) without thermal derating |
| Low clamping ratio (VC/VBR ≈ 1.39) | Minimizes overvoltage stress on downstream components during transient events |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36AHE3_A/H | Same SMB package, identical VBR/VWM/VC, but HE3 suffix indicates RoHS/AEC-Q101 without halogen-free claim | Acceptable where halogen-free material is not mandated (e.g., industrial, non-automotive) | Select when cost optimization is prioritized and halogen-free compliance is not required by end-customer specification |
| TPSMB36AHM3_A/I | Identical electrical and mechanical specs; differs only in packaging - 3200-piece 13" tape-and-reel vs. 750-piece 7" reel | No functional difference; suited for high-volume SMT production lines with large feeder capacity | Choose for automated manufacturing runs requiring extended reel life and reduced changeover frequency |
Compared with SMBJ36AHE3_A/H and TPSMB36AHM3_A/I, the TPSMB36AHM3_A/H uniquely combines halogen-free construction, AEC-Q101 qualification, and 7" reel packaging - making it optimal for automotive Tier 1 suppliers needing full material compliance and medium-batch flexibility.

FAQ
What is the exact breakdown voltage range for TPSMB36AHM3_A/H?
The TPSMB36AHM3_A/H has a guaranteed breakdown voltage (VBR) range of 34.2 V to 37.8 V at 1 mA test current, with a nominal value of 36.0 V. This range is measured per ANSI/IEEE C62.35 and confirmed in Vishay's official datasheet revision 23-Jan-2024 (Document Number: 88406). The TPSMB36AHM3_A/H maintains this specification across its full operating temperature range.
Is TPSMB36AHM3_A/H qualified for automotive applications?
Yes, the TPSMB36AHM3_A/H carries the HM3 suffix, indicating it is halogen-free, RoHS-compliant, and AEC-Q101 qualified. It undergoes rigorous stress testing including temperature cycling, high-temperature reverse bias, and mechanical shock - validating its suitability for automotive powertrain and body electronics. The TPSMB36AHM3_A/H meets all requirements specified in the AEC-Q101 standard for discrete semiconductors.
What does the "HM3" in TPSMB36AHM3_A/H signify?
The "HM3" suffix in TPSMB36AHM3_A/H denotes Vishay's halogen-free, RoHS-compliant, and AEC-Q101-qualified variant. It distinguishes the part from HE3 versions (RoHS/AEC-Q101 but not halogen-free) and confirms compliance with automotive material restrictions. The TPSMB36AHM3_A/H also meets JESD201 Class 2 whisker resistance and MSL Level 1 reflow specifications.
What is the clamping voltage of TPSMB36AHM3_A/H at its rated surge current?
The TPSMB36AHM3_A/H clamps to a maximum of 49.9 V at its rated peak pulse current (IPPM) of 12 A under the standardized 10/1000 µs waveform. This clamping voltage is measured per JEDEC test conditions and represents the highest voltage imposed on protected circuitry during full-rated transient events. The TPSMB36AHM3_A/H achieves this with minimal overshoot due to its low dynamic impedance.
Can TPSMB36AHM3_A/H replace TPSMB36AHE3_A/H in an existing design?
Yes, the TPSMB36AHM3_A/H is a direct replacement for TPSMB36AHE3_A/H in terms of electrical characteristics, package (SMB/DO-214AA), pinout, and thermal performance. The only differences are material-related: HM3 adds halogen-free compliance while retaining AEC-Q101 qualification and RoHS status. No PCB or schematic changes are needed when substituting TPSMB36AHM3_A/H for TPSMB36AHE3_A/H.
