Product details
Overview
TPSMC36HE3/57T 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 at 1 mA), 30.8 V stand-off voltage (VWM), 1500 W peak pulse power (10/1000 µs), 30.1 V clamping voltage at 30.1 A peak current, and operates up to +185 °C junction temperature - ideal for automotive power line and sensor interface protection.
For engineers reviewing the TPSMC36HE3/57T datasheet, TPSMC36HE3/57T pinout, TPSMC36HE3/57T application, or TPSMC36HE3/57T equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, MSL Level 1 rating, 185 °C thermal capability, and verified clamping performance under 10/1000 µs surge conditions.
Technical Context
The TPSMC36HE3/57T employs passivated anisotropic rectifier technology with optimized junction passivation for stable avalanche behavior under repetitive transients. Its unidirectional architecture provides low-leakage reverse blocking (≤1.0 µA at VWM) and fast response time (<1 ns), enabling effective suppression of ESD and inductive switching spikes on DC power rails.
Rated for 1500 W peak pulse power per 10/1000 µs waveform and 200 A non-repetitive forward surge current (8.3 ms half-sine), it maintains clamping integrity across -65 °C to +185 °C operating range and meets JESD201 Class 2 whisker resistance requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 34.2 / 36.0 / 37.8 V at 1 mA - defines precise avalanche initiation threshold for predictable overvoltage triggering |
| VWM | 30.8 V - maximum continuous reverse working voltage before leakage exceeds 1.0 µA |
| VC @ IPPM | 49.9 V at 30.1 A - clamping voltage during full-rated 1500 W transient, limiting downstream stress |
| PPPM | 1500 W (10/1000 µs) - peak surge energy handling capacity without failure |
| TJ max. | +185 °C - enables use in under-hood automotive and high-temperature industrial environments |
| Polarity | Unidirectional - blocks reverse current only; requires correct orientation relative to protected rail |
| Package | SMC (DO-214AB) - industry-standard surface-mount outline with 8.0 mm × 8.0 mm copper pad requirement |
Pinout & Package
TPSMC36HE3/57T uses the SMC (DO-214AB) package: molded epoxy case with matte tin-plated leads, cathode indicated by a color band. Mounting requires 0.31″ × 0.31″ (8.0 mm × 8.0 mm) copper pads per terminal per Vishay specification.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction or clamping | Connected to lower-potential side of protected circuit (e.g., GND or return path) |
| Cathode | Current exit point during reverse-biased clamping | Connected to higher-potential rail (e.g., 24 V supply); marked by color band |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JEDEC standards |

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 VWM (30.8 V) and VC (49.9 V), but lower PPPM = 600 W and smaller SMB package (DO-214AA) | Limited to lower-energy transients; not rated for AEC-Q101 or 185 °C operation | Select when space-constrained layouts require smaller footprint and surge energy is ≤600 W |
| TPSMC36AHM3/57T | Identical electrical specs and AEC-Q101 qualification; differs only in halogen-free molding compound (HM3 suffix) | No functional difference; HM3 variant required where halogen-free compliance is mandated | Choose HM3 version for RoHS+halogen-free programs; HE3 remains optimal for cost-sensitive AEC-Q101 designs |
Compared with SMBJ36A, TPSMC36HE3/57T delivers 2.5× higher surge power handling and automotive-grade thermal robustness; versus TPSMC36AHM3/57T, it offers identical protection performance with standard RoHS-compliant materials - making it the preferred choice for high-reliability 24 V/48 V system protection where halogen content is unrestricted.

FAQ
What is the clamping voltage of the TPSMC36HE3/57T at its rated peak pulse current?
The TPSMC36HE3/57T has a maximum clamping voltage (VC) of 49.9 V when subjected to its rated peak pulse current of 30.1 A under the standard 10/1000 µs waveform. This value is measured per Figure 1 in Vishay Document 88407 and defines the upper voltage limit imposed on protected circuitry during worst-case surge events. The TPSMC36HE3/57T maintains this clamping performance across its full operating temperature range.
Is the TPSMC36HE3/57T qualified for automotive applications?
Yes, the TPSMC36HE3/57T is AEC-Q101 qualified, as confirmed in the Vishay datasheet revision 19-Jan-2024 (Document Number 88407). It undergoes rigorous stress testing including high-temperature reverse bias, temperature cycling, and ESD per JEDEC standards. The HE3 suffix explicitly denotes RoHS-compliant and AEC-Q101 qualified construction, making TPSMC36HE3/57T suitable for under-hood and chassis-mounted automotive electronics.
What is the maximum operating junction temperature for the TPSMC36HE3/57T?
The TPSMC36HE3/57T supports a maximum junction temperature (TJ) of +185 °C, enabling reliable operation in high-thermal-load environments such as engine control units, power inverters, and industrial motor drives. This rating is validated per Vishay's thermal derating curves (Figure 2) and allows full 1500 W pulse power capability at ambient temperatures up to +125 °C when mounted on specified 8.0 mm × 8.0 mm copper pads.
Does the TPSMC36HE3/57T have unidirectional or bidirectional polarity?
The TPSMC36HE3/57T is a unidirectional TVS diode, as stated in the "FEATURES" section of the Vishay datasheet. It functions as a reverse-biased avalanche device - conducting only when the cathode is at a higher potential than the anode. Polarity is marked by a color band on the cathode end, and incorrect orientation will prevent proper clamping. Bidirectional variants (e.g., TPSMC36CA) are separate part numbers.
What is the standoff voltage (VWM) and leakage current specification for the TPSMC36HE3/57T?
The TPSMC36HE3/57T has a maximum working peak reverse voltage (VWM) of 30.8 V at 25 °C, with reverse leakage current (IR) limited to ≤1.0 µA at that voltage. At elevated temperature (TJ = 150 °C), leakage increases to ≤15 µA - still within safe limits for most 24 V and 48 V systems. These values ensure minimal power loss and no false triggering during normal operation of the TPSMC36HE3/57T.
