Product details
Overview
TPSMB36AHE3_A/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode designed for clamping inductive and lightning-induced transients 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) - deployed in automotive ECUs, industrial sensor interfaces, and telecom power supplies.
For engineers reviewing the TPSMB36AHE3_A/H datasheet, TPSMB36AHE3_A/H pinout, TPSMB36AHE3_A/H application, or TPSMB36AHE3_A/H equivalent, key selection criteria include unidirectional polarity, SMB (DO-214AA) package compatibility, AEC-Q101 qualification, 185 °C junction temperature rating, and clamping performance under repetitive 10/1000 µs surge conditions.
Technical Context
This TVS diode operates as a voltage-clamping protection device in parallel with sensitive downstream circuitry. Its silicon avalanche structure provides sub-nanosecond response to transients, with low incremental surge resistance ensuring minimal overshoot during 12 A IPPM events at 10/1000 µs waveform.
The device is rated for continuous operation from –65 °C to +185 °C junction temperature and meets MSL Level 1 per J-STD-020 (260 °C reflow peak). Its cathode-band polarity marking and matte tin-plated terminals comply with J-STD-002 solderability and JESD 22-B102 whisker testing requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 34.2 / 36.0 / 37.8 V - defines precise avalanche initiation threshold for reliable overvoltage triggering |
| VWM | 30.8 V - maximum continuous reverse operating voltage before leakage exceeds 1 µA |
| VC @ IPPM | 49.9 V - clamped voltage seen by protected circuit during full 12 A transient event |
| PPPM | 600 W - peak surge power dissipation capability under standardized 10/1000 µs waveform |
| TJ max. | +185 °C - enables use in under-hood automotive and high-temperature industrial environments |
| Polarity | Unidirectional - protects against positive-going transients only; requires correct cathode orientation |
| Package | SMB (DO-214AA) - industry-standard surface-mount outline with 5.0 mm × 5.0 mm copper pad thermal requirement |
Pinout & Package
TPSMB36AHE3_A/H uses the SMB (DO-214AA) surface-mount package: a molded plastic case with two coplanar leads, cathode identified by a color band. Thermal performance requires 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal per datasheet Fig. 2 derating curve.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient current sink | Connected to protected line; conducts avalanche current to ground during overvoltage |
| Anode | Reference return path | Typically tied to system ground or low-impedance return plane for clamping reference |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD stress per AEC standard |
| Junction passivated anisotropic rectifier | Reduces parameter drift and improves long-term stability under thermal cycling and humidity exposure |
| MSL Level 1 (260 °C peak) | Enables single-pass lead-free reflow without moisture-related popcorn failure |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients, improving protection margin for downstream ICs |
| 185 °C TJ rating | Supports placement near heat sources (e.g., power MOSFETs, DC/DC converters) without derating |
Applications
| Automotive Body Control Module (BCM) | Industrial PLC Digital Input Protection |
|---|---|
Use Scenario: Protecting 12 V supply rail and LIN bus lines in BCMs from load dump and inductive switching spikes.

IC Role / Device Role / Timing Role: Low-leakage (1 µA @ 30.8 V) standoff device that activates only during >34.2 V transients. Use Value: Enables direct connection to noisy motor circuits without false triggering or standby power penalty. |
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; lower TJ max. (150 °C) | Not suitable for automotive under-hood use; acceptable for commercial/industrial power rails | Select SMBJ36A only when AEC-Q101 compliance and 185 °C operation are not required |
| TPSMB36AHM3_A/H | Halogen-free variant of same die; identical electrical specs and AEC-Q101 qualification; same SMB package | No functional difference; selected only when halogen-free material compliance is mandated | Choose TPSMB36AHM3_A/H if RoHS + halogen-free certification (per JEDEC J-STD-202) is required |
Compared with SMBJ36A and TPSMB36AHM3_A/H, the TPSMB36AHE3_A/H delivers identical clamping performance and automotive qualification but with standard RoHS-compliant (non-halogen-free) construction - making it the default choice for cost-sensitive AEC-Q101 designs where halogen content is unrestricted.

FAQ
What is the breakdown voltage tolerance for TPSMB36AHE3_A/H?
The TPSMB36AHE3_A/H has a specified breakdown voltage range of 34.2 V (minimum) to 37.8 V (maximum) at 1 mA test current, with 36.0 V nominal. This ±5% tolerance ensures predictable clamping onset across production lots while maintaining compatibility with 30.8 V stand-off and 49.9 V clamping requirements defined in the datasheet.
Is TPSMB36AHE3_A/H suitable for bidirectional transient protection?
No, TPSMB36AHE3_A/H is unidirectional only, as confirmed in the "Features" section of the Vishay datasheet (Document Number: 88406). It protects against positive transients on the cathode side relative to anode. For bidirectional protection, a separate device such as P6SMB36CA or equivalent dual-diode configuration is required.
Does TPSMB36AHE3_A/H require heatsinking in standard PCB layouts?
TPSMB36AHE3_A/H does not require external heatsinking when mounted per datasheet recommendations: 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads at each terminal. Its SMB package and 600 W pulse rating are thermally optimized for short-duration transients; steady-state power dissipation is negligible due to low leakage (<1 µA at 30.8 V).
What is the meaning of the "HE3" and "_A/H" suffixes in TPSMB36AHE3_A/H?
The "HE3" suffix indicates RoHS-compliant, AEC-Q101-qualified construction with matte tin plating and JESD 201 Class 2 whisker resistance. The "_A/H" denotes revision code "A" and packaging in 7" diameter tape-and-reel (H = 750 units per reel), per Vishay's ordering information table in Document 88406.
How does TPSMB36AHE3_A/H perform at elevated ambient temperatures?
TPSMB36AHE3_A/H maintains full specification down to –65 °C and up to +185 °C junction temperature. At 125 °C ambient, its peak pulse power is derated to ~420 W (70% of 600 W) per Fig. 2 in the datasheet, while VBR shifts predictably using αT = 0.090 %/°C - ensuring stable clamping behavior across automotive and industrial thermal profiles.
