Product details
Overview
TPSMC13A-2HE3_A/I from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in DO-214AB (SMC) package, with 12.4 V minimum breakdown voltage, 11.1 V standoff voltage, 18.2 V clamping voltage at 82.4 A peak pulse current, and 1500 W peak pulse power rating. It protects MOSFETs, ICs, and sensor signal lines in automotive and industrial power electronics against inductive switching transients.
For engineers reviewing the TPSMC13A-2HE3_A/I datasheet, TPSMC13A-2HE3_A/I pinout, TPSMC13A-2HE3_A/I application, or TPSMC13A-2HE3_A/I equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 185 °C junction temperature rating, and DO-214AB thermal and mechanical compatibility with high-reliability PCB layouts.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to deliver stable clamping under repetitive surge stress. Its 185 °C maximum junction temperature and MSL Level 1 rating support reflow soldering at 260 °C and operation in under-hood automotive environments.
The device responds in sub-nanosecond time to transients and maintains low incremental surge resistance during 10/1000 μs waveform events. Clamping performance is specified at 82.4 A IPPM with VC = 18.2 V, enabling robust protection of 12 V rail interfaces without excessive voltage overshoot.

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 | Lower PPPM (400 W), same DO-214AC (SMA) package, 13 V nominal VBR | Not AEC-Q101 qualified; limited to commercial-temperature industrial use | Select when cost sensitivity outweighs automotive qualification and surge energy requirements |

FAQ
What is the clamping voltage of the TPSMC13A-2HE3_A/I under maximum surge conditions?
The TPSMC13A-2HE3_A/I clamps to 18.2 V when subjected to its rated 82.4 A peak pulse current (IPPM) using the standard 10/1000 μs waveform. This value is measured at TA = 25 °C and defines the upper voltage limit imposed on protected circuitry during transient events. The TPSMC13A-2HE3_A/I maintains this clamping performance across its full operating temperature range, supporting robust design margins in automotive and industrial applications.
Is the TPSMC13A-2HE3_A/I suitable for automotive applications?
Yes, the TPSMC13A-2HE3_A/I is AEC-Q101 qualified and rated for operation up to +185 °C junction temperature, making it suitable for under-hood automotive applications such as engine control units, body control modules, and ADAS power supplies. Its DO-214AB package, MSL Level 1 rating, and validated reliability testing per JESD22 and J-STD-020 ensure compatibility with automotive manufacturing and field-use requirements. The TPSMC13A-2HE3_A/I meets these standards without derating in typical vehicle thermal environments.
What does the "-2HE3_A/I" suffix indicate in TPSMC13A-2HE3_A/I?
The "-2HE3_A/I" suffix denotes RoHS-compliant construction (HE3), ±5 % tolerance revision code "A", and 13-inch tape-and-reel packaging (I). The "2" indicates the device is unidirectional, and "A" confirms the 12.4–13.7 V breakdown voltage range. This full suffix identifies the exact manufacturing release, material compliance, and logistics format-ensuring traceability and correct assembly for the TPSMC13A-2HE3_A/I in production environments.
How does the TPSMC13A-2HE3_A/I compare to bidirectional TVS diodes in circuit protection?
The TPSMC13A-2HE3_A/I is unidirectional and designed for DC power line protection where only positive transients occur relative to ground. Unlike bidirectional devices, it offers lower leakage (<2 μA at 11.1 V) and tighter VBR tolerance, improving efficiency in always-on 12 V systems. Bidirectional variants cannot replace the TPSMC13A-2HE3_A/I without redesigning biasing and grounding-so the TPSMC13A-2HE3_A/I remains optimal for dedicated positive-rail clamping in automotive and industrial DC networks.
What is the maximum surge current the TPSMC13A-2HE3_A/I can withstand?
The TPSMC13A-2HE3_A/I withstands a non-repetitive peak forward surge current (IFSM) of 200 A under an 8.3 ms single half-sine waveform, per JEDEC standards. This rating applies when mounted on 8.0 mm × 8.0 mm copper pads at each terminal and ensures survival during severe load-dump events in automotive 12 V systems. The TPSMC13A-2HE3_A/I sustains this surge without parametric shift or physical damage, provided layout and thermal management meet Vishay's recommended pad dimensions.
