Product details
Overview
TPSMC16AHE3/57T 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 16.0 V nominal breakdown voltage (VBR), 13.6 V stand-off voltage (VWM), 1500 W peak pulse power (10/1000 µs), 66.7 A peak pulse current (IPPM), and 22.5 V maximum clamping voltage (VC) - deployed in automotive sensor protection and industrial power supply input stages.
For engineers reviewing the TPSMC16AHE3/57T datasheet, TPSMC16AHE3/57T pinout, TPSMC16AHE3/57T application, or TPSMC16AHE3/57T equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 185 °C junction temperature rating, low incremental surge resistance, and compatibility with high-reliability PCB layouts requiring MSL Level 1 handling and JESD201 Class 2 whisker resistance.
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 enables robust suppression of inductive switching spikes and ESD-induced surges without degradation under thermal stress.
The device operates exclusively in unidirectional mode with cathode-band polarity marking, and achieves 22.5 V clamping at 66.7 A IPPM, ensuring predictable overvoltage protection for 12 V–15 V rail systems. Its 0.078 %/°C VBR temperature coefficient supports accurate voltage margining in automotive under-hood environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 15.2 / 16.0 / 16.8 V - ensures reliable triggering above 13.6 V system stand-off voltage while avoiding false trips during normal operation. |
| VWM | 13.6 V - maximum continuous reverse voltage before leakage exceeds 1 µA, compatible with 12 V nominal automotive and industrial rails. |
| VC @ IPPM | 22.5 V - clamping voltage at 66.7 A peak pulse, limiting downstream IC stress to safe levels during 1500 W transient events. |
| PPPM | 1500 W - peak pulse power handling per 10/1000 µs waveform, sufficient for ISO 7637-2 Pulse 1/2a/5a and IEC 61000-4-5 surge immunity. |
| TJ max. | +185 °C - extended junction temperature rating enables use in high-ambient under-hood automotive locations without derating. |
| Polarity | Unidirectional - protects against positive-going transients only; requires correct orientation relative to protected line polarity. |
| MSL Level | Level 1 (per J-STD-020) - supports standard reflow profiles up to 260 °C peak without moisture-related failure risk. |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, matte tin-plated leads, cathode indicated by color band. Dimensions: 7.11 mm × 6.22 mm × 2.90 mm (L × W × H).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal during forward conduction | Connected to lower-potential side of protected circuit; defines unidirectional clamping direction. |
| Cathode | Current exit terminal during forward conduction; marked by band | Connected to higher-potential side (e.g., VIN rail); determines clamping threshold relative to reference ground. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing - required for front-end protection in ADAS and body control modules. |
| 1500 W peak pulse power | Enables single-device protection against severe load-dump and inductive kick events without cascaded TVS staging. |
| Low clamping ratio (VC/VBR = 1.41) | Minimizes overvoltage overshoot during surge events, reducing stress on downstream MOSFETs and gate drivers. |
| 0.078 %/°C VBR tempco | Ensures predictable breakdown shift across wide ambient ranges - critical for maintaining safety margins in engine bay applications. |
| Junction temperature rating: +185 °C | Supports uninterrupted operation in high-thermal-stress zones such as near power converters or motor drivers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16A | Lower peak pulse power (400 W), same VWM/VBR range, SMA package (smaller footprint, lower thermal mass) | Not AEC-Q101 qualified; limited to commercial/industrial use where automotive reliability is not required | Select SMAJ16A only for cost-sensitive, non-automotive designs with lower surge exposure and tighter board space constraints. |
| TPSMC16AHM3/57T | Identical electrical specs and AEC-Q101 qualification; halogen-free molding compound (vs. RoHS-compliant only in HE3) | Required for strict environmental compliance programs (e.g., EU automotive Tier 1 mandates) where halogen content must be zero | Choose TPSMC16AHM3/57T when halogen-free certification is contractually mandated, otherwise TPSMC16AHE3/57T satisfies all functional and reliability requirements. |
Compared with SMAJ16A and TPSMC16AHM3/57T, the TPSMC16AHE3/57T delivers full automotive-grade surge robustness (1500 W, +185 °C, AEC-Q101) in a thermally superior SMC package, while offering RoHS compliance without halogen-free overhead - making it the optimal balance of reliability, regulatory alignment, and thermal performance for mainstream automotive and industrial designs.

FAQ
What is the clamping voltage of the TPSMC16AHE3/57T at its rated peak pulse current?
The TPSMC16AHE3/57T has a maximum clamping voltage (VC) of 22.5 V at its specified peak pulse current (IPPM) of 66.7 A, measured using the standardized 10/1000 µs waveform. This value is guaranteed across the full operating temperature range and forms the basis for downstream IC overvoltage margining. The TPSMC16AHE3/57T maintains this clamping performance without degradation under repeated surge stress when mounted per recommended pad layout.
Is the TPSMC16AHE3/57T qualified for automotive applications?
Yes, the TPSMC16AHE3/57T is AEC-Q101 qualified, having passed rigorous stress tests including high-temperature reverse bias, temperature cycling, and ESD per JESD22 standards. Its +185 °C maximum junction temperature and MSL Level 1 rating further validate its suitability for under-hood and chassis-mounted automotive systems. The TPSMC16AHE3/57T is explicitly designated for automotive use via its HE3 suffix per Vishay's ordering nomenclature.
What is the difference between TPSMC16AHE3/57T and TPSMC16AHM3/57T?
The TPSMC16AHE3/57T and TPSMC16AHM3/57T share identical electrical specifications, AEC-Q101 qualification, and SMC packaging. The sole difference is material composition: TPSMC16AHE3/57T is RoHS-compliant, while TPSMC16AHM3/57T adds halogen-free certification. Both meet JESD201 Class 2 whisker resistance and MSL Level 1. The TPSMC16AHE3/57T remains the default choice unless halogen-free compliance is contractually required.
Does the TPSMC16AHE3/57T have bidirectional capability?
No, the TPSMC16AHE3/57T is strictly unidirectional, as confirmed in the Vishay datasheet under FEATURES and ELECTRICAL CHARACTERISTICS. It protects against positive-going transients only, with polarity defined by the cathode band. For bidirectional protection, a separate device such as the TPSMC16CA would be required - the TPSMC16AHE3/57T must be oriented correctly in-circuit to ensure proper clamping function.
What is the maximum leakage current of the TPSMC16AHE3/57T at its stand-off voltage?
The TPSMC16AHE3/57T exhibits a maximum reverse leakage current (IR) of 1.0 µA at its 13.6 V stand-off voltage (VWM) and 25 °C ambient temperature. At elevated junction temperatures (e.g., 150 °C), leakage increases to 10 µA - still well within design margins for most 12 V rail protection applications. This low leakage ensures minimal power loss and no interference with upstream voltage regulation in the TPSMC16AHE3/57T's intended use cases.
