Product details
Overview
TPSMA16AHE3/61T from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMA (DO-214AC) 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), 22.0 V maximum clamping voltage (VC) at 17.8 A peak pulse current, 400 W peak pulse power (10/1000 µs), and 185 °C maximum junction temperature - enabling robust protection in automotive power supply rails and industrial sensor interfaces.
For engineers reviewing the TPSMA16AHE3/61T datasheet, TPSMA16AHE3/61T pinout, TPSMA16AHE3/61T application, or TPSMA16AHE3/61T equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification status, 1.0 W steady-state power dissipation, low incremental surge resistance, and compatibility with automated SMT assembly under J-STD-020 MSL level 1 conditions.
Technical Context
The TPSMA16AHE3/61T employs passivated anisotropic rectifier technology to achieve stable clamping performance across -65 °C to +185 °C operating range. Its junction passivation enables high-temperature reliability and meets AEC-Q101 stress test requirements for automotive electronics.
This TVS diode operates exclusively in unidirectional mode with cathode-band polarity marking, delivering fast response time (<1 ns) and excellent clamping ratio (VC/VBR ≈ 1.375). It is rated for 40 A non-repetitive forward surge current (8.3 ms half-sine) and exhibits low thermal resistance due to optimized SMA package copper pad layout per JEDEC DO-214AC standard.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 15.2 V / 16.0 V / 16.8 V - defines minimum voltage at which device enters avalanche conduction under 1.0 mA test current |
| VWM | 13.6 V - maximum continuous reverse working voltage before leakage exceeds 1.0 μA at 25 °C |
| VC @ IPPM | 22.0 V at 17.8 A - clamped voltage during 400 W transient event; determines protected circuit's maximum overvoltage exposure |
| PPPM | 400 W (10/1000 µs waveform) - peak transient energy handling capacity under standardized surge condition |
| TJ max. | +185 °C - enables operation in under-hood automotive environments and high-power industrial enclosures without derating |
| Polarity | Unidirectional - blocks reverse current only; requires correct orientation relative to protected line polarity |
| Package | SMA (DO-214AC) - industry-standard surface-mount outline with 0.208" x 0.157" footprint and matte tin-plated leads |
Pinout & Package
Package: SMA (DO-214AC), molded plastic case meeting UL 94 V-0 flammability rating; terminals are matte tin plated, solderable per J-STD-002 and JESD 22-B102; cathode identified by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point during clamping | Connected to lower-potential side of protected line (e.g., ground or return path); conducts during positive transients when cathode is at higher potential |
| Cathode | Avalanche conduction terminal | Connected to higher-potential side (e.g., VIN, signal line); initiates clamping when reverse voltage exceeds VBR; marked by color band |
Key Features
| Feature | Design Value |
|---|---|
| Junction passivation | Enables stable VBR drift < ±5 % over 1000 hrs at 150 °C, critical for long-life automotive modules |
| AEC-Q101 qualification | Validated for automotive-grade reliability including HTGB, HTRB, and temperature cycling per stress test plan |
| MSL level 1 | Supports reflow up to 260 °C peak without moisture-induced damage; no bake required prior to assembly |
| Low clamping ratio | VC/VBR = 22.0/16.0 = 1.375 - minimizes overvoltage stress on downstream ICs compared to higher-ratio TVS devices |
| 400 W pulse power | Handles ISO 7637-2 Pulse 1 (inductive switch-off) and Pulse 2a (load dump initiation) waveforms in 12 V systems |
Applications
| Automotive Power Rail Protection | Industrial Sensor Signal Line Clamping |
|---|---|
|
Use Scenario: Protecting 12 V battery-fed ECUs against load dump and alternator transients per ISO 7637-2. IC Role / Device Role / Timing Role: Unidirectional TVS placed between VBAT and chassis ground to clamp surges above 13.6 V.

IC Role / Device Role / Timing Role: TVS connected between signal and return path to shunt fast transients before reaching ADC input stage. Use Value: Sub-1 ns response ensures clamping occurs before sensitive op-amps or isolators experience overstress, preserving measurement integrity. |

Use Scenario: Protecting remote radio head (RRH) power feeds from lightning-induced surges on outdoor telecom infrastructure. IC Role / Device Role / Timing Role: TVS installed at DC input connector to divert induced common-mode surges to ground plane. Use Value: 185 °C TJ max. supports operation inside sealed, sun-exposed enclosures where ambient exceeds 105 °C. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16A | Same VBR (16.0 V) and VC (22.0 V), but SMB package (DO-214AA); 600 W PPPM rating | Higher pulse power margin; larger footprint may limit routing density in compact PCBs | Select SMBJ16A when system-level surge testing exceeds 400 W or board space permits larger package |
| TPSMA16AHM3/61T | Identical electrical specs and SMA package; halogen-free molding compound and whisker-resistant plating | Required for RoHS-compliant, halogen-free BOMs in EU/Asia markets; same AEC-Q101 qualification | Choose TPSMA16AHM3/61T when material compliance (IEC 61249-2-21) is mandatory for final product certification |
Compared with TPSMA16AHE3/61T, SMBJ16A offers higher surge margin in a larger package, while TPSMA16AHM3/61T provides identical protection with enhanced environmental compliance - both require no schematic change but may impact layout or sourcing strategy.

FAQ
What is the AEC-Q101 qualification status of the TPSMA16AHE3/61T?
The TPSMA16AHE3/61T is AEC-Q101 qualified, as confirmed in Vishay document 88405 (Revision 23-Jan-2024). This qualification covers stress tests including high-temperature reverse bias, temperature cycling, and unbiased highly accelerated stress testing - validating its suitability for automotive powertrain and body electronics applications. The HE3 suffix explicitly denotes AEC-Q101 compliance per ordering code definition.
Does the TPSMA16AHE3/61T support lead-free reflow soldering?
Yes, the TPSMA16AHE3/61T supports lead-free reflow soldering with a maximum peak temperature of 260 °C, meeting J-STD-020 MSL level 1 requirements. Its matte tin-plated leads are solderable per J-STD-002 and JESD 22-B102, and it passes JESD 201 class 2 whisker testing - ensuring reliable interconnects in modern RoHS-compliant manufacturing lines.
What is the maximum clamping voltage of the TPSMA16AHE3/61T under surge conditions?
The TPSMA16AHE3/61T has a maximum clamping voltage (VC) of 22.0 V at 17.8 A peak pulse current (IPPM), measured using the standardized 10/1000 µs double-exponential waveform. This value defines the upper voltage limit imposed on protected circuitry during a 400 W transient event and is verified per ANSI/IEEE C62.35 test methodology.
How does the TPSMA16AHE3/61T differ from the TPSMA16AHM3/61T?
The TPSMA16AHE3/61T and TPSMA16AHM3/61T share identical electrical specifications, package (SMA), and AEC-Q101 qualification. The key difference lies in materials: HM3 uses halogen-free molding compound and meets additional whisker resistance requirements (JESD 201 class 2), whereas HE3 is RoHS-compliant but not halogen-free. Both are drop-in replacements electrically.
Can the TPSMA16AHE3/61T be used in bidirectional configurations?
No, the TPSMA16AHE3/61T is unidirectional only, as stated in the Vishay datasheet. It conducts in reverse bias above VBR but blocks forward current beyond its 3.5 V forward voltage at 25 A. For bidirectional protection, two TPSMA16AHE3/61T devices must be connected in series opposition - or a dedicated bidirectional TVS such as SMBJ16CA should be selected instead.
