Product details
Overview
SMAJ6.0-E3/61 from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in DO-214AC (SMA) package, designed for clamping voltage transients on power and signal lines. It features 6.0 V stand-off voltage (VWM), 11.4 V maximum clamping voltage (VC) at 35.1 A peak pulse current, and 400 W peak pulse power rating with 10/1000 µs waveform - suitable for protecting MOSFETs, ICs, and sensor interfaces in automotive and industrial control systems.
For engineers reviewing the SMAJ6.0-E3/61 datasheet, SMAJ6.0-E3/61 pinout, SMAJ6.0-E3/61 application, or SMAJ6.0-E3/61 equivalent, this page provides verified electrical parameters, thermal resistance data, RoHS-compliant packaging details, and validated alternative parts for ESD and surge protection design-in.
Technical Context
This unidirectional TVS diode operates by avalanche breakdown above its 6.0 V stand-off voltage, delivering fast response (<1 ps) to transient events such as inductive switching spikes and ESD. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (≤800 µA at VWM).
Thermal performance is defined by RθJA = 120 °C/W (on 5.0 × 5.0 mm copper pads) and RθJL = 30 °C/W, enabling reliable operation up to TJ = +150 °C. It meets MSL Level 1 per J-STD-020 and passes JESD201 Class 1A whisker testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum continuous reverse operating voltage before conduction begins; sets minimum system operating margin. |
| VBR (min/max) | 6.67 V / 8.15 V at 10 mA - Verified breakdown range ensures predictable turn-on across temperature and unit variation. |
| VC @ IPPM | 11.4 V at 35.1 A - Clamping voltage during 10/1000 µs surge defines worst-case overvoltage seen by protected circuitry. |
| PPPM | 400 W - Peak pulse power handling capacity under standard 10/1000 µs waveform; derates above 78 V. |
| IFSM | 40 A - Single half-sine surge rating (8.3 ms) supports robustness against repetitive line surges in AC-coupled applications. |
| TJ Range | –55 °C to +150 °C - Full industrial temperature operation without derating; enables under-hood or motor-control deployment. |
Pinout & Package
Package: DO-214AC (SMA), surface-mount, matte tin-plated leads, RoHS-compliant, MSL Level 1, 260 °C reflow compatible.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or lowest potential node; current flows anode-to-cathode during clamping. |
| Cathode (banded end) | High-side transient sink | Connected to protected line; absorbs positive transients by shunting to ground through anode. |
Key Features
| Feature | Design Value |
|---|---|
| 400 W peak pulse power | Supports high-energy transients (e.g., ISO 7637-2 Pulse 1/2a/5a) without degradation on standard PCB layouts. |
| Glass-passivated junction | Ensures stable VBR tolerance and long-term reliability under thermal cycling and humidity stress. |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (e.g., ESD contact discharge), improving protection margin. |
| MSL Level 1 rating | Enables direct placement into high-volume SMT lines without baking or special handling prior to reflow. |
Applications
| Automotive Power Line Protection | Industrial Sensor Interface Protection |
|---|---|
|
Use Scenario: Protecting 12 V battery-fed ECUs from load dump and alternator ripple. IC Role / Device Role: Unidirectional TVS placed between power rail and chassis ground to clamp positive transients. Use Value: Limits voltage to ≤11.4 V during 35.1 A surges, preventing damage to 16 V-rated regulators and CAN transceivers. |
Use Scenario: Shielding analog output lines of pressure/temperature sensors in PLC modules. IC Role / Device Role: Low-capacitance TVS on 4–20 mA or 0–10 V signal paths to suppress field-induced noise. Use Value: Maintains signal integrity with <1 nA leakage at 6.0 V, avoiding offset errors in precision measurement circuits. |
| Consumer Power Adapter Input Stage | MOSFET Gate Driver Protection |
|
Use Scenario: Secondary-side DC bus protection in USB PD and Qi wireless charging adapters. IC Role / Device Role: Standoff-rated TVS absorbing flyback spikes from synchronous rectifiers. Use Value: Withstands 40 A non-repetitive forward surge (8.3 ms), surviving repeated adapter plug/unplug events. |
Use Scenario: Clamping gate-source voltage of N-channel MOSFETs in motor drivers. IC Role / Device Role: Fast-response TVS connected between gate and source to prevent VGS overstress. Use Value: Sub-nanosecond response time limits VGS excursion to ≤11.4 V, preserving gate oxide integrity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.0A-E3/61 | Lower VBR range (6.67–7.37 V); tighter 10% VWM tolerance; 10.3 V VC at 38.8 A. | Better suited for low-voltage logic rails where tighter clamping consistency is required. | Select when VBR uniformity across production lots is critical for fail-safe threshold alignment. |
| SMBJ6.0-E3/52 | DO-214AA (SMB) package; same VWM/VC specs but higher PPPM (600 W); RθJA = 90 °C/W. | Preferred for higher-power surge environments (e.g., telecom power feeds) where footprint increase is acceptable. | Choose when system-level surge tests exceed 400 W and thermal management allows larger pad area. |
Compared with SMAJ6.0-E3/61, SMAJ6.0A-E3/61 offers tighter VBR control at slightly reduced surge capability, while SMBJ6.0-E3/52 delivers higher power handling in a larger footprint - both require layout review due to differing thermal and mechanical constraints.

FAQ
What is the maximum clamping voltage of SMAJ6.0-E3/61 under a 10/1000 µs surge?
The SMAJ6.0-E3/61 exhibits a maximum clamping voltage (VC) of 11.4 V when subjected to its rated peak pulse current of 35.1 A using the standardized 10/1000 µs waveform. This value is measured at TA = 25 °C on recommended 5.0 × 5.0 mm copper pads and defines the upper voltage limit imposed on protected circuitry during transient events.
Is SMAJ6.0-E3/61 unidirectional or bidirectional?
SMAJ6.0-E3/61 is a unidirectional Transient Voltage Suppressor, indicated by the absence of "C" or "CA" suffix and confirmed by its cathode band marking. It conducts only during positive transients relative to its cathode terminal and must be oriented with cathode toward the protected line and anode to ground.
Does SMAJ6.0-E3/61 meet automotive qualification standards?
SMAJ6.0-E3/61 is commercial-grade (E3 suffix) and not AEC-Q101 qualified. For automotive applications requiring qualification, the HE3-suffix variant (e.g., SMAJ6.0HE3/61) is specified and tested per AEC-Q101. Always verify qualification status via Vishay's official documentation before use in safety-critical vehicle systems.
What is the thermal resistance junction-to-ambient for SMAJ6.0-E3/61?
The typical thermal resistance junction-to-ambient (RθJA) for SMAJ6.0-E3/61 is 120 °C/W when mounted on 0.2 × 0.2 inch (5.0 × 5.0 mm) copper pads per terminal. This value assumes standard JEDEC test conditions and is essential for calculating junction temperature rise under sustained power dissipation.
Can SMAJ6.0-E3/61 replace SMAJ6.0A-E3/61 in existing designs?
SMAJ6.0-E3/61 and SMAJ6.0A-E3/61 share identical package, polarity, and mounting, but differ in VBR range (6.67–8.15 V vs. 6.67–7.37 V) and clamping voltage (11.4 V vs. 10.3 V). Replacement requires validation of system-level overvoltage margins, especially in low-tolerance 5 V or 3.3 V rail protection where tighter VC may be advantageous.
