Product details
Overview
TPSMC36AHE3_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 a 36 V nominal breakdown voltage (VBR), 30.8 V stand-off voltage (VWM), 1500 W peak pulse power (10/1000 μs), 49.9 V maximum clamping voltage at 30.1 A, and operates up to +185 °C junction temperature - used in automotive power rail protection and industrial sensor interface circuits.
For engineers reviewing the TPSMC36AHE3_B/H datasheet, TPSMC36AHE3_B/H pinout, TPSMC36AHE3_B/H application, or TPSMC36AHE3_B/H equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, MSL Level 1 rating, 1.0 μA reverse leakage at VWM, and thermal stability under high-temperature automotive environments.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology with optimized junction passivation for stable clamping performance across temperature. Its 185 °C maximum junction temperature and AEC-Q101 qualification confirm suitability for under-hood automotive applications where thermal stress and reliability are critical.
The device delivers 1500 W peak pulse power per 10/1000 μs waveform with low incremental surge resistance and fast response time, enabling effective suppression of ESD, load dump, and inductive switching transients on 12 V and 24 V systems without sacrificing forward conduction integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 34.2 / 36.0 / 37.8 V - defines precise voltage threshold at which clamping initiates under 1 mA test current |
| VWM | 30.8 V - maximum continuous working voltage before leakage exceeds 1.0 μA, ensuring no false triggering in normal operation |
| VC @ IPPM | 49.9 V at 30.1 A - clamped voltage during worst-case 1500 W transient, limiting downstream IC stress |
| PPPM | 1500 W - peak pulse power handling capability with 10/1000 μs waveform, meeting ISO 7637-2 and ISO 16750-2 surge requirements |
| TJ max. | +185 °C - enables reliable operation in engine control units, body controllers, and other high-temperature automotive locations |
| Polarity | Unidirectional - protects only against positive transients relative to cathode, requiring correct orientation in DC-biased rails |
| MSL Level | Level 1 (260 °C peak reflow) - supports standard lead-free SMT assembly without moisture sensitivity concerns |
Pinout & Package

| 1500 W peak pulse power (10/1000 μs) | Withstands severe load-dump events in 12 V/24 V vehicle electrical systems per ISO 16750-2 |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (<1 ns rise time), improving protection margin |
| Meets MSL Level 1 | Enables direct placement into reflow ovens without baking, reducing manufacturing complexity and cost |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ36A-E3/5A (Vishay) | Lower PPPM (400 W), SMA package (smaller footprint, lower thermal mass), same VBR range | Not rated for AEC-Q101; limited to commercial/industrial ambient (TJ max = +150 °C) | Select when space-constrained layouts preclude SMC and automotive qualification is unnecessary |
| 1.5KE36A (ON Semiconductor) | Through-hole DO-201 package, higher VF (3.5 V), identical VBR/VC specs, non-AEC-Q101 | Requires wave soldering; unsuitable for fully SMT production or high-vibration environments | Choose for legacy through-hole designs or prototyping where rework tolerance outweighs automated assembly needs |
Compared with TPSMC36AHE3_B/H, SMAJ36A-E3/5A offers smaller size but sacrifices automotive qualification and surge robustness, while 1.5KE36A provides identical clamping performance in through-hole form but lacks SMT compatibility and high-temperature reliability - making TPSMC36AHE3_B/H the optimal choice for production automotive and industrial SMT systems.

FAQ
What is the maximum clamping voltage of the TPSMC36AHE3_B/H under peak surge conditions?
The TPSMC36AHE3_B/H has a maximum clamping voltage (VC) of 49.9 V at 30.1 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is measured per standard test conditions and ensures downstream components see no more than 49.9 V during worst-case transients. The TPSMC36AHE3_B/H maintains this clamping performance across its full operating temperature range up to +185 °C junction temperature.
Is the TPSMC36AHE3_B/H qualified for automotive applications?
Yes, the TPSMC36AHE3_B/H is AEC-Q101 qualified, as confirmed by Vishay's documentation and ordering code suffix "HE3", which denotes RoHS-compliant and AEC-Q101 qualified construction. It meets automotive reliability requirements including temperature cycling, humidity bias, and mechanical shock testing - making it suitable for engine control units, body electronics, and ADAS power domains.
What package type does the TPSMC36AHE3_B/H use, and what are its key mechanical features?
The TPSMC36AHE3_B/H uses the SMC (DO-214AB) surface-mount package, measuring 7.11 mm × 6.22 mm × 2.90 mm. Key mechanical features include matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, MSL Level 1 rating (260 °C peak reflow), UL 94 V-0 molding compound, and cathode identification via molded color band - all verified in Vishay document 88407.
How does the TPSMC36AHE3_B/H compare to bidirectional TVS diodes in circuit design?
The TPSMC36AHE3_B/H is unidirectional only, meaning it clamps positive transients relative to cathode and conducts like a rectifier in forward bias. Unlike bidirectional variants, it must be oriented correctly on DC-biased lines and cannot protect AC signals or bipolar transients. Its advantage lies in lower leakage (<1.0 μA at 30.8 V) and tighter VBR tolerance versus bidirectional equivalents - critical for precision power rail protection.
What is the reverse leakage current specification for the TPSMC36AHE3_B/H at its stand-off voltage?
The TPSMC36AHE3_B/H specifies a maximum reverse leakage current (IR) of 1.0 μA at its stand-off voltage (VWM) of 30.8 V and ambient temperature of 25 °C. At elevated junction temperature (TJ = 150 °C), leakage increases to 15 μA - a value explicitly listed in the Electrical Characteristics table of Vishay document 88407 for the TPSMC36A variant.
