Product details
Overview
TPSMC36AHE3_A/I 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), 30.1 A peak pulse current (IPPM), and 49.9 V maximum clamping voltage (VC) - deployed in automotive sensor protection and industrial power supply inputs.
For engineers reviewing the TPSMC36AHE3_A/I datasheet, TPSMC36AHE3_A/I pinout, TPSMC36AHE3_A/I application, or TPSMC36AHE3_A/I equivalent, key selection criteria include its AEC-Q101 qualification, 185 °C junction temperature rating, unidirectional polarity, low leakage (<1.0 µA at VWM), and MSL Level 1 moisture sensitivity.
Technical Context
This TVS diode operates as a voltage-clamping protection device using passivated anisotropic rectifier technology, with fast response time and low incremental surge resistance to limit transient overvoltage before downstream components are damaged. Its 10/1000 µs waveform capability and derating curve support robust surge handling across ambient temperatures up to +125 °C.
The device is rated for non-repetitive surge events only, with IFSM = 200 A (8.3 ms half-sine) and VF = 3.5 V at 100 A forward current. Its cathode-anode configuration and color-band polarity marking align with standard SMC (DO-214AB) mechanical layout and soldering requirements per J-STD-002 and JESD 22-B102.
Key Specifications

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-E3/52 (Vishay) | Same VBR/VC specs but SMB (DO-214AA) package; 600 W PPPM, lower IPPM (16.7 A) | Limited to lower-energy transients; not AEC-Q101 qualified in this variant | Select when board space is constrained and surge threat level is ≤600 W (e.g., consumer USB ports) |
| TPSMC36CAHE3_A/I (Vishay) | Bi-directional version; identical package, VBR, and PPPM, but supports ±36 V clamping | Required for AC-coupled or bidirectional signal lines (e.g., RS-485, audio) | Choose only if protecting differential or alternating-polarity signals; adds no benefit for unidirectional DC rails |
Compared with SMBJ36A-E3/52, TPSMC36AHE3_A/I delivers 2.5× higher surge power handling and automotive qualification; versus TPSMC36CAHE3_A/I, it offers tighter leakage (<1.0 µA vs. <2.0 µA at VWM) and lower capacitance for DC power-line use.

FAQ
What is the maximum clamping voltage of the TPSMC36AHE3_A/I under rated surge conditions?
The TPSMC36AHE3_A/I has a maximum clamping voltage (VC) of 49.9 V when subjected to its rated peak pulse current of 30.1 A (10/1000 µs waveform). This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during transient events. The TPSMC36AHE3_A/I maintains this clamping performance across its full operating temperature range and after repeated surge exposure, provided derating guidelines from Figure 2 are followed.
Is the TPSMC36AHE3_A/I suitable for automotive applications?
Yes, the TPSMC36AHE3_A/I is AEC-Q101 qualified and explicitly designed for automotive use, with a maximum junction temperature of +185 °C and validation across HTOL, temperature cycling, and humidity testing. Its HE3 suffix denotes RoHS-compliance and automotive qualification. The TPSMC36AHE3_A/I is commonly deployed in engine control units, body electronics, and ADAS sensor modules where protection against load dump and ISO 7637-2 transients is required.
What does the "HE3" suffix indicate in TPSMC36AHE3_A/I?
"HE3" indicates a RoHS-compliant, AEC-Q101 qualified version with matte tin-plated leads and JESD 201 Class 2 whisker resistance. The "A" denotes the revision code, and "I" specifies packaging in 13-inch tape-and-reel format (3500 units per reel). The TPSMC36AHE3_A/I meets MSL Level 1 and is rated for peak reflow temperatures up to 260 °C, making it compatible with standard lead-free SMT assembly processes without preconditioning.
How does the TPSMC36AHE3_A/I compare to the TPSMC36CAHE3_A/I variant?
The TPSMC36AHE3_A/I is unidirectional, while TPSMC36CAHE3_A/I is bidirectional - meaning the latter clamps both positive and negative transients symmetrically around 0 V. Both share identical package, breakdown voltage, and peak power rating, but the unidirectional TPSMC36AHE3_A/I exhibits lower reverse leakage (<1.0 µA at VWM) and is preferred for DC power-line protection. The TPSMC36AHE3_A/I should not be substituted for bidirectional signal-line applications like RS-485 without circuit redesign.
What is the recommended PCB pad layout for the TPSMC36AHE3_A/I?
Vishay specifies mounting on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads at each terminal to achieve rated 1500 W pulse power dissipation. The SMC (DO-214AB) outline requires minimum anode/cathode pad widths of 0.060" (1.52 mm), with overall land pattern matching the mechanical drawing on page 4 of document 88407. Thermal relief and solid copper pour beneath the device improve heat spreading and surge endurance. The TPSMC36AHE3_A/I must be oriented with the cathode band aligned to the designated PCB silkscreen polarity mark.
