Product details
Overview
TPSMC36AHE3_A/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for clamping inductive switching surges and lightning-induced transients. It features 36 V breakdown voltage (VBR = 34.2–37.8 V at 1 mA), 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 - deployed in automotive powertrain control units and industrial motor drive signal lines.
For engineers reviewing the TPSMC36AHE3_A/H datasheet, TPSMC36AHE3_A/H pinout, TPSMC36AHE3_A/H application, or TPSMC36AHE3_A/H equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal derating curves, SMC package mechanical dimensions, and direct alternative part comparisons for ESD and surge protection design-in.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology with optimized junction passivation for stable clamping under high-temperature operation. Its unidirectional polarity enables forward-biased surge conduction only during reverse overvoltage events, and its low incremental surge resistance ensures minimal voltage overshoot during fast transients.
The device meets MSL Level 1 per J-STD-020 with 260 °C reflow peak, supports 200 A non-repetitive forward surge current (8.3 ms half-sine), and exhibits a +0.090 %/°C temperature coefficient of VBR, enabling predictable voltage shift across -65 °C to +185 °C operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 34.2 V / 36.0 V / 37.8 V at 1 mA - defines precise reverse breakdown threshold for reliable clamping onset |
| VWM | 30.8 V - maximum continuous reverse working voltage before leakage exceeds 1 μA |
| VC @ IPPM | 49.9 V at 30.1 A - peak clamped voltage during 1500 W transient, limiting stress on downstream ICs |

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 suitable for 1500 W load-dump; limited to board-level ESD and low-energy transients | Select when space-constrained and surge energy <400 W; avoid for automotive power rail protection |
| 1.5KE36A (ON Semiconductor) | Through-hole DO-201 package, identical VBR/VC specs, higher IFSM (250 A), no AEC-Q101 qualification | Requires wave soldering; not rated for automotive under-hood thermal cycling or vibration | Use in industrial AC/DC supplies where AEC-Q101 is unnecessary and through-hole mounting is preferred |
Compared with SMAJ36A-E3/5A and 1.5KE36A, TPSMC36AHE3_A/H uniquely combines 1500 W surge rating, SMC surface-mount compatibility, +185 °C operation, and AEC-Q101 qualification - making it the only option qualified for high-energy, high-temperature automotive and industrial power-line protection.

FAQ
What is the maximum clamping voltage of TPSMC36AHE3_A/H at its rated peak pulse current?
The TPSMC36AHE3_A/H has a maximum clamping voltage (VC) of 49.9 V at its peak pulse current (IPPM) of 30.1 A, measured under the standard 10/1000 µs waveform. This value ensures downstream components like 3.3 V or 5 V microcontrollers remain within safe operating limits during surge events. The clamping performance is guaranteed across the full operating temperature range and is validated per ANSI/IEEE C62.35 standards. TPSMC36AHE3_A/H maintains this specification without degradation after multiple surge cycles when mounted per recommended pad layout.
Is TPSMC36AHE3_A/H qualified for automotive applications?
Yes, TPSMC36AHE3_A/H is AEC-Q101 qualified, as confirmed by Vishay's official documentation and ordering code suffix "HE3", which denotes RoHS compliance and automotive-grade reliability testing. It undergoes stress tests including high-temperature reverse bias (HTRB), temperature cycling, and unbiased highly accelerated stress testing (uHAST). The device is rated for junction temperatures up to +185 °C and meets MSL Level 1 handling requirements - making TPSMC36AHE3_A/H suitable for engine control units, body electronics, and ADAS power domains.
What does the "HE3" suffix in TPSMC36AHE3_A/H indicate?
The "HE3" suffix in TPSMC36AHE3_A/H specifies that the device is RoHS-compliant, AEC-Q101 qualified, and passes JESD201 Class 2 whisker testing on matte tin-plated terminals. The "H" denotes the tape-and-reel packaging format (7-inch reel, 850 units), and "A" is the revision code. This suffix distinguishes it from HM3 variants (halogen-free) and non-automotive versions, ensuring traceability to qualified manufacturing lots and material composition per Vishay's compliance framework.
How does TPSMC36AHE3_A/H compare to TPSMC36AHM3_A/H?
TPSMC36AHE3_A/H and TPSMC36AHM3_A/H share identical electrical specifications, package (SMC), and AEC-Q101 qualification. The sole difference is material composition: HE3 uses standard RoHS-compliant materials, while HM3 adds halogen-free certification per IEC 61249-2-21. Both meet UL 94 V-0 and J-STD-020 MSL Level 1. Designers selecting TPSMC36AHE3_A/H prioritize cost-optimized automotive compliance; those specifying TPSMC36AHM3_A/H require halogen-free bill-of-materials for specific regional environmental mandates.
What is the reverse leakage current of TPSMC36AHE3_A/H at maximum operating temperature?
At VWM = 30.8 V and TJ = 150 °C, the TPSMC36AHE3_A/H exhibits a maximum reverse leakage current (ID) of 15 μA, as specified in Vishay's Electrical Characteristics table. This value remains well below typical microcontroller input leakage thresholds and ensures minimal power loss in always-on circuits. At room temperature (25 °C), leakage is ≤1.0 μA - confirming stable performance across the full -65 °C to +185 °C junction range without thermal runaway risk.
