Product details
Overview
TPSMC36HE3_A/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for high-reliability overvoltage protection of sensitive electronics. It features a 36 V nominal breakdown voltage (VBR = 34.2–37.8 V), 30.8 V stand-off voltage (VWM), 1500 W peak pulse power (10/1000 µs), 49.9 V clamping voltage at 30.1 A, and 185 °C maximum junction temperature - enabling use in automotive power rails and industrial sensor interfaces.
For engineers reviewing the TPSMC36HE3_A/H datasheet, TPSMC36HE3_A/H pinout, TPSMC36HE3_A/H application, or TPSMC36HE3_A/H equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, MSL Level 1 rating, 260 °C reflow compatibility, and verified clamping performance under 10/1000 µs surge conditions.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology to deliver stable clamping across -65 °C to +185 °C operating range, with temperature coefficient of VBR at +0.090 %/°C. Its low incremental surge resistance and fast response time ensure effective suppression of transients induced by inductive switching and ESD events.
The device is rated for 200 A non-repetitive forward surge current (8.3 ms half-sine), exhibits 1.0 µA max reverse leakage at VWM, and maintains clamping integrity under repeated thermal stress - validated per JESD22-B102 whisker testing and J-STD-020 moisture sensitivity Level 1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 34.2 V / 36.0 V / 37.8 V - defines precise voltage threshold at which avalanche conduction begins under 1 mA test current |
| VWM | 30.8 V - maximum continuous reverse working voltage before significant leakage occurs |
| VC @ IPPM | 49.9 V at 30.1 A - clamping voltage during 10/1000 µs surge, limiting downstream IC stress |
| PPPM | 1500 W - peak pulse power handling capability under standardized waveform, critical for automotive load-dump immunity |
| TJ max | +185 °C - enables operation in under-hood automotive environments and high-temperature industrial enclosures |
| Polarity | Unidirectional - protects against positive-going transients only; requires correct cathode orientation in circuit |
| MSL Level | Level 1 (J-STD-020) - supports standard SMT reflow without dry-pack or baking requirements |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, matte tin-plated leads, UL 94 V-0 molding compound. Cathode identified by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current return path | Connected to ground or low-impedance reference; carries full surge current during clamping |
| Cathode | Protected line connection | Connected to signal/power line being protected; voltage referenced to anode during clamping |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36A | Same VBR range (34.2–37.8 V), lower PPPM = 600 W, SMB package (smaller footprint, lower thermal mass) | Limited to lower-energy transients; unsuitable for automotive load-dump where 1500 W is mandated | Select when space-constrained and surge energy ≤600 W; verify thermal dissipation in PCB layout |
| TPSMC36AHM3_A/H | Identical electrical specs; halogen-free molding compound vs. RoHS-compliant only in TPSMC36HE3_A/H | No functional difference; HM3 suffix required for halogen-free compliance in specific OEM supply chains | Choose HM3 version if halogen-free material declaration is contractually required; otherwise HE3 suffices |
Compared with SMBJ36A, TPSMC36HE3_A/H delivers 2.5× higher surge power handling and superior high-temperature reliability; compared with TPSMC36AHM3_A/H, it offers identical protection performance with standard RoHS compliance - making it optimal for cost-sensitive automotive and industrial designs where halogen-free is not mandated.

FAQ
What is the clamping voltage of TPSMC36HE3_A/H at its rated peak pulse current?
The TPSMC36HE3_A/H has a maximum clamping voltage (VC) of 49.9 V at 30.1 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuits during surge events. The clamping performance is guaranteed across the full operating temperature range and forms the basis for downstream IC voltage margining in designs using TPSMC36HE3_A/H.
Is TPSMC36HE3_A/H qualified for automotive applications?
Yes, TPSMC36HE3_A/H is AEC-Q101 qualified, as confirmed in the Vishay datasheet (Document Number: 88407, Revision: 19-Jan-2024). It meets rigorous stress tests including high-temperature reverse bias, temperature cycling, and mechanical shock - all required for under-hood and body-control module deployment. The "HE3" suffix explicitly denotes RoHS-compliant and AEC-Q101 qualified variants, making TPSMC36HE3_A/H suitable for automotive power rail and sensor protection without additional qualification effort.
What does the "HE3" suffix mean in TPSMC36HE3_A/H?
The "HE3" suffix in TPSMC36HE3_A/H indicates RoHS-compliant construction and AEC-Q101 qualification. It distinguishes this variant from non-automotive versions and confirms compliance with JEDEC JESD201 Class 2 whisker resistance, J-STD-020 MSL Level 1, and 260 °C peak reflow tolerance. The "_A/H" portion specifies revision code "A" and packaging in 7″ tape-and-reel (H = 850 units/reel). This full ordering code ensures traceability to qualified manufacturing lots for TPSMC36HE3_A/H.
Can TPSMC36HE3_A/H replace TPSMC36A in existing designs?
TPSMC36HE3_A/H is a direct replacement for TPSMC36A in new designs, offering identical electrical specifications (VBR, VWM, VC, PPPM) plus AEC-Q101 qualification and enhanced process controls. However, legacy TPSMC36A may lack the HE3 suffix's RoHS compliance and automotive qualification documentation. For production continuity, verify that the bill-of-materials explicitly references TPSMC36HE3_A/H to ensure compliance alignment - especially in automotive or medical programs requiring certified components.
What is the maximum reverse leakage current for TPSMC36HE3_A/H at 25 °C and 150 °C?
At 25 °C, TPSMC36HE3_A/H exhibits a maximum reverse leakage current (IR) of 1.0 µA at its 30.8 V stand-off voltage (VWM). At elevated temperature (TJ = 150 °C), the maximum leakage increases to 15 µA under the same VWM condition - as specified in the Electrical Characteristics table. This temperature-dependent leakage behavior is inherent to silicon avalanche structures and must be accounted for in ultra-low-power sensor bias networks where TPSMC36HE3_A/H is deployed.
