Product details
Overview
TPSMC36HE3_A/I 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 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 clamping voltage at 30.1 A, and operates up to +185 °C junction temperature - ideal for automotive power rail and sensor line protection.
For engineers reviewing the TPSMC36HE3_A/I datasheet, TPSMC36HE3_A/I pinout, TPSMC36HE3_A/I application, or TPSMC36HE3_A/I equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, MSL Level 1 rating, 1000 µA max reverse leakage at VWM, and compatibility with high-temperature PCB reflow profiles up to 260 °C.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology to deliver stable clamping performance under repetitive surge stress. Its 185 °C maximum junction temperature and AEC-Q101 qualification confirm suitability for under-hood automotive environments where thermal cycling and long-term reliability are critical.
The device exhibits low incremental surge resistance and fast response time (<1 ns), enabling effective suppression of transients induced by inductive load switching and ESD events. Clamping behavior is characterized per ANSI/IEEE C62.35, with validated performance across -65 °C to +185 °C operating range and 10/1000 µs waveform compliance.
Key Specifications

Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V/24 V battery-fed ECUs from load dump and alternator transients per ISO 7637-2. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power rail and chassis ground to clamp surges above 30.8 V. Use Value: Limits peak rail voltage to ≤49.9 V during 1500 W transients, preventing damage to MCU power supplies and CAN transceivers. |
Use Scenario: Shielding analog sensor outputs (e.g., pressure, temperature) from ESD and cable discharge events in factory automation. IC Role / Device Role / Timing Role: TVS connected between signal line and ground to shunt fast transients before reaching ADC input stage. Use Value: Sub-1 ns response ensures clamping occurs before 100 ns ESD pulse reaches sensitive front-end circuitry. |
| Telecom DC Power Input Protection | Computer Peripheral Port Protection |
Use Scenario: Safeguarding PoE-powered equipment inputs against lightning-induced surges on 48 V DC lines. IC Role / Device Role / Timing Role: Primary overvoltage clamp on DC input before DC-DC converter stage. Use Value: 185 °C rating allows reliable operation inside sealed telecom enclosures with limited airflow. |
Use Scenario: Protecting USB, HDMI, or DisplayPort hot-swap connectors from human-body-model (HBM) ESD events. IC Role / Device Role / Timing Role: Low-capacitance TVS (typ. <100 pF at 0 V) placed inline with differential signal pairs. Use Value: 1 µA max leakage at 30.8 V avoids signal integrity degradation while providing >15 kV HBM protection. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ36A-E3/5AT | Lower PPPM (400 W), SMA package (smaller footprint), same VWM/VBR range, non-AEC-Q101 | Limited to consumer/industrial use; insufficient for automotive load dump | Select when space-constrained and surge energy <400 W; not suitable for AEC-Q101 designs |
| TPSMC36AHM3_A/I | Identical electrical specs; HM3 suffix adds halogen-free construction (vs. HE3's RoHS-only) | No functional difference; chosen only when halogen-free compliance is mandated | Drop-in replacement if halogen-free requirement applies; otherwise TPSMC36HE3_A/I preferred for cost |
Compared with SMAJ36A-E3/5AT and TPSMC36AHM3_A/I, the TPSMC36HE3_A/I uniquely combines 1500 W surge capability, AEC-Q101 qualification, and SMC package robustness - making it the only choice for automotive power rail protection requiring ISO 7637-2 compliance.

FAQ
What is the maximum clamping voltage of the TPSMC36HE3_A/I under standard test conditions?
The TPSMC36HE3_A/I has a maximum clamping voltage (VC) of 49.9 V when subjected to a 10/1000 µs surge current of 30.1 A. This value is measured per ANSI/IEEE C62.35 and represents the peak voltage imposed on protected circuitry during worst-case transient events. The TPSMC36HE3_A/I maintains this clamping performance across its full operating temperature range, supporting robust design margins in automotive and industrial applications.
Is the TPSMC36HE3_A/I qualified for automotive applications?
Yes, the TPSMC36HE3_A/I is AEC-Q101 qualified and carries the HE3 suffix indicating RoHS compliance and automotive-grade reliability. It undergoes full qualification testing including temperature cycling, humidity bias, and mechanical shock - meeting requirements for engine control, body electronics, and ADAS subsystems. The TPSMC36HE3_A/I is explicitly listed in Vishay's AEC-Q101 documentation for the TPSMCxxA series.
What does the "A/I" suffix mean in TPSMC36HE3_A/I?
The "A/I" suffix in TPSMC36HE3_A/I denotes the revision code ("A") and packaging format ("I" = 13-inch diameter plastic tape and reel, 3500 units per reel). This ordering code aligns with Vishay's standardized nomenclature in Document Number 88407. The "HE3" portion confirms RoHS compliance and AEC-Q101 qualification, while "TPSMC36" specifies the 36 V nominal breakdown variant within the SMC-package TVS family.
Can the TPSMC36HE3_A/I replace older TPSMC36A variants in existing designs?
Yes, the TPSMC36HE3_A/I is a direct replacement for legacy TPSMC36A parts with identical electrical characteristics, SMC (DO-214AB) package dimensions, and pinout. The HE3 suffix adds AEC-Q101 qualification and RoHS compliance without altering performance - enabling drop-in upgrades in automotive and industrial designs. No PCB layout changes are required when migrating to TPSMC36HE3_A/I from non-qualified TPSMC36A versions.
What is the reverse leakage current specification for TPSMC36HE3_A/I at rated stand-off voltage?
The TPSMC36HE3_A/I specifies a maximum reverse leakage current (IR) of 1.0 µA at its stand-off voltage (VWM = 30.8 V) and ambient temperature (TA = 25 °C). At elevated junction temperatures (e.g., 150 °C), leakage increases to ≤15 µA - a value verified in Vishay's Electrical Characteristics table. This low leakage ensures minimal power loss and signal interference in always-on automotive systems using the TPSMC36HE3_A/I.
