Product details
Overview
TPSMC13HE3_A/I from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in DO-214AB (SMC) package, designed for high-energy surge protection on power and signal lines. It features 13 V breakdown voltage (VBR = 11.7–14.3 V), 10.5 V stand-off voltage (VWM), 19 V clamping voltage (VC) at 78.9 A peak pulse current, and 1500 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive ECUs and industrial sensor interfaces.
For engineers reviewing the TPSMC13HE3_A/I datasheet, TPSMC13HE3_A/I pinout, TPSMC13HE3_A/I application, or TPSMC13HE3_A/I equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 185 °C junction temperature rating, low incremental surge resistance, and compatibility with automated SMT assembly under J-STD-020 MSL Level 1.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to deliver stable clamping performance across -65 °C to +185 °C operating range. Its 10/1000 µs waveform response supports IEC 61000-4-5 surge immunity up to 1 kV (line-to-earth) when properly mounted on 8.0 mm × 8.0 mm copper pads.
The device operates exclusively in unidirectional mode with cathode band marking, exhibits ≤2 µA reverse leakage at VWM, and maintains clamping stability under repetitive surge stress due to low thermal resistance and optimized junction passivation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 11.7 V / 14.3 V - ensures reliable turn-on above system nominal voltage while avoiding false triggering during transients |
| VWM | 10.5 V - maximum continuous reverse working voltage compatible with 12 V automotive supply rails |
| VC @ IPPM | 19 V - clamps 78.9 A surge to safe level for downstream MOSFETs or CAN transceivers |
| PPPM | 1500 W - handles high-energy transients from inductive load switching per ISO 7637-2 Pulse 1/2a/5a |
| TJ max | +185 °C - enables operation in under-hood automotive environments without derating |
| IFSM | 200 A - withstands 8.3 ms half-sine surge events common in motor drive and relay coil suppression |

| Thermal stability | Derates linearly from 100 % at 25 °C to ~65 % at 125 °C per Fig. 2 |
| Lead finish | Matte tin per J-STD-002 - supports lead-free reflow and eliminates whisker risk (JESD 201 Class 2) |
Applications
| Automotive Power Rail Protection | Industrial Sensor Signal Line Clamp |
|---|---|
Use Scenario: Protecting 12 V battery-fed control modules (e.g., body control units) against load dump and alternator ripple. IC Role / Device Role / Timing Role: Shunt-type transient suppressor placed between power rail and chassis ground. Use Value: Clamps ISO 16750-2 load dump surges (up to 35 V, 400 ms) to <19 V, preserving MCU and CAN transceiver integrity. |
Use Scenario: Safeguarding analog outputs of pressure/temperature sensors in PLC I/O modules exposed to field wiring ESD. IC Role / Device Role / Timing Role: Unidirectional TVS placed across sensor output and ground to absorb IEC 61000-4-2 contact discharge. Use Value: Limits transient voltage to ≤19 V within 1 ns, preventing latch-up in op-amp front-ends and ADC inputs. |
| Automotive CAN Bus Interface | DC Motor Drive Gate Protection |
Use Scenario: Secondary protection on CAN_H/CAN_L lines downstream of primary common-mode choke and ESD diodes. IC Role / Device Role / Timing Role: High-power TVS pair (one per line) referenced to ground to handle differential surges exceeding 1 kV.

Use Scenario: Suppressing flyback voltage spikes generated by brushed DC motor commutation in automotive seat/mirror actuators. IC Role / Device Role / Timing Role: Unidirectional clamp across motor terminals to divert inductive kickback away from H-bridge MOSFETs. Use Value: Limits VDS stress on N-channel MOSFETs to <19 V, eliminating need for snubber RC networks and reducing BOM count. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13A-E3/5AT | Same VWM (10.5 V), lower PPPM (400 W), SMA package (smaller footprint, higher thermal resistance) | Limited to low-energy transients (e.g., ESD only); unsuitable for ISO 7637-2 Pulse 5a | Select when space-constrained and surge energy <300 W; verify thermal margin on 25 mm² pads |
| 1.5KE13A | Through-hole TO-204AA (DO-41), same VBR/VC, PPPM = 1500 W, but no AEC-Q101 qualification | Not qualified for automotive use; requires manual insertion and wave soldering | Use only in non-automotive industrial controls where AEC-Q101 is not mandated |
Compared with SMAJ13A-E3/5AT and 1.5KE13A, the TPSMC13HE3_A/I delivers automotive-grade reliability in surface-mount form with superior thermal dissipation via SMC pad layout, enabling robust protection in high-vibration, high-temperature environments without compromising PCB automation.

FAQ
What is the maximum clamping voltage of the TPSMC13HE3_A/I at its rated peak pulse current?
The TPSMC13HE3_A/I has a maximum clamping voltage (VC) of 19 V at its specified peak pulse current (IPPM) of 78.9 A, measured using a 10/1000 µs waveform. This value is guaranteed across the full operating temperature range and ensures downstream components like microcontrollers or CAN transceivers remain within safe voltage limits during surge events. The TPSMC13HE3_A/I achieves this clamping performance through optimized junction design and low dynamic impedance.
Is the TPSMC13HE3_A/I qualified for automotive applications?
Yes, the TPSMC13HE3_A/I is AEC-Q101 qualified, having passed all required stress tests including high-temperature operating life (HTOL), temperature cycling (TC), and unbiased highly accelerated stress testing (UHAST). Its 185 °C maximum junction temperature rating and DO-214AB package construction meet stringent automotive under-hood requirements. The TPSMC13HE3_A/I is explicitly listed in Vishay's AEC-Q101 qualified product list for transient voltage suppressors.
What does the "HE3_A/I" suffix indicate in TPSMC13HE3_A/I?
The "HE3" denotes RoHS-compliant, matte tin-plated leads meeting JESD 201 Class 2 whisker resistance; "A" indicates ±5 % tolerance on VBR; and "I" specifies packaging in 13-inch diameter plastic tape and reel with 3500 units per reel. This full suffix confirms the TPSMC13HE3_A/I is the automotive-grade, high-reliability variant intended for automated SMT assembly with full process compatibility and traceability.
How does the TPSMC13HE3_A/I compare to bidirectional TVS diodes in surge protection design?
The TPSMC13HE3_A/I is unidirectional and must be used with correct polarity - anode to line, cathode to ground - making it ideal for DC power rails and single-ended signal lines. Unlike bidirectional variants, it provides lower leakage (<2 µA at VWM) and tighter VBR tolerance, improving noise immunity in sensitive analog paths. The TPSMC13HE3_A/I is not suitable for AC or differential bus protection without external circuitry.
What PCB layout guidance applies to the TPSMC13HE3_A/I for optimal thermal and electrical performance?
Vishay specifies mounting the TPSMC13HE3_A/I on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads at each terminal to achieve rated 1500 W pulse power. Minimum trace width should be 1.5 mm, and ground plane connection must be low-inductance. Avoid thermal relief on pads; use solid copper fills. The TPSMC13HE3_A/I's DO-214AB outline requires strict adherence to the 7.75 mm × 8.13 mm mounting footprint shown in Figure 4 of document 88407.
