Product details
Overview
SMA5J6.0-E3/61 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-214AC (SMA) package, designed for high-energy surge protection on DC power lines and signal paths. It features 6.0 V stand-off voltage (VWM), 6.67–7.37 V breakdown voltage (VBR), 500 W peak pulse power (PPPM), and clamps transients to ≤10.3 V at 48.5 A peak pulse current (IPPM). It is widely used in automotive electronics for protecting microcontrollers and sensor interfaces against load dump and inductive switching.
For engineers reviewing the SMA5J6.0-E3/61 datasheet, SMA5J6.0-E3/61 pinout, SMA5J6.0-E3/61 application, or SMA5J6.0-E3/61 equivalent, key selection criteria include unidirectional polarity, 10.3 V clamping voltage at rated surge current, RoHS-compliant matte tin-plated leads, AEC-Q101 qualification, and compatibility with automated SMT placement on standard 0.2" × 0.2" copper pads.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>800 μA leakage at 6.0 V), but conducts heavily when reverse voltage exceeds its 6.67–7.37 V breakdown range, diverting surge energy away from downstream ICs. Its glass-passivated junction ensures stable performance and low incremental surge resistance.
The device is rated for 150 °C maximum junction temperature, has thermal resistance of 80 °C/W (junction-to-ambient) and 25 °C/W (junction-to-lead), and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak. It is qualified to AEC-Q101 for automotive reliability and supports uni-directional surge suppression only - no bi-directional operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum continuous reverse operating voltage before conduction begins; defines safe DC bias margin. |
| VBR min/max | 6.67 V / 7.37 V - Measured at 10 mA test current; ensures predictable turn-on threshold across production lot. |
| VC @ IPPM | ≤10.3 V - Clamping voltage at 48.5 A (10/1000 µs waveform); determines maximum stress imposed on protected circuitry. |
| PPPM | 500 W - Peak pulse power handling (10/1000 µs); enables robust protection against ISO 7637-2 Pulse 1/2a/5a surges. |
| ID @ VWM | ≤800 µA - Reverse leakage at 6.0 V; low enough to avoid loading sensitive 5 V logic or sensor supply rails. |
| TJ max | +150 °C - Maximum junction temperature; supports under-hood automotive deployment without derating at 125 °C ambient. |
Pinout & Package
Package: DO-214AC (SMA), surface-mount, low-profile plastic case with matte tin-plated leads. Cathode indicated by a band on the body; anode is unmarked end. Complies with UL 94 V-0 flammability rating and J-STD-002/JESD 22-B102 solderability standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / Surge return path | Connected to ground or low-impedance return plane; completes shunt path during transient events. |
| Cathode | Reverse-biased terminal / Protection node | Connected to protected line (e.g., 5 V rail or CAN_H); blocks normal operation, conducts during overvoltage. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable VBR tolerance and long-term reliability under thermal cycling and humidity exposure. |
| AEC-Q101 qualification | Validates suitability for automotive applications including engine control units, body electronics, and ADAS sensor interfaces. |
| MSL Level 1 rating | Enables single-reflow assembly without moisture sensitivity concerns; peak reflow up to 260 °C permitted. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J6.0AHE3/61 | AEC-Q101 qualified version with identical electrical specs; HE3 suffix denotes whisker-test class 2 compliance. | Required for automotive safety-critical modules where enhanced metallurgical reliability is mandated. | Select SMA5J6.0AHE3/61 when AEC-Q101 full qualification documentation and JESD 201 class 2 whisker resistance are contractually required. |
| P6SMB6.0A | Same VWM (6.0 V) and VC (10.3 V), but lower PPPM (600 W), larger DO-214AA (SMB) package, and higher RθJA (100 °C/W). | Better suited for non-automotive industrial applications where board space allows larger footprint and thermal management is less constrained. | Choose P6SMB6.0A if higher pulse power margin is needed and DO-214AA mounting is acceptable; not drop-in compatible due to different pad layout. |
Compared with SMA5J6.0AHE3/61, the SMA5J6.0-E3/61 offers identical surge performance but lacks formal AEC-Q101 certification documentation; versus P6SMB6.0A, it provides tighter board area usage and superior thermal resistance, though with lower absolute pulse power rating.

FAQ
What is the polarity configuration of the SMA5J6.0-E3/61?
The SMA5J6.0-E3/61 is a unidirectional transient voltage suppressor diode. Its cathode is marked by a band on the DO-214AC (SMA) package body; the unmarked end is the anode. This configuration allows it to block reverse voltage up to 6.0 V and conduct only during positive transients on the cathode side - making it suitable for DC power line protection where polarity is fixed. The SMA5J6.0-E3/61 does not support bi-directional operation.
Does the SMA5J6.0-E3/61 meet automotive qualification standards?
The SMA5J6.0-E3/61 is RoHS-compliant and manufactured to Vishay's commercial-grade specifications, but it is not AEC-Q101 qualified. For automotive applications requiring formal qualification, the pin-compatible SMA5J6.0AHE3/61 variant must be selected. The SMA5J6.0-E3/61 shares identical electrical parameters and package dimensions with the HE3 version, but lacks the extended reliability testing and documentation required for AEC-Q101 compliance. Always verify qualification status using the full part number - SMA5J6.0-E3/61 is not certified.
What is the maximum clamping voltage of the SMA5J6.0-E3/61 under surge conditions?
The SMA5J6.0-E3/61 clamps to a maximum of 10.3 V when subjected to its rated peak pulse current of 48.5 A, measured using the standardized 10/1000 µs double-exponential waveform. This clamping voltage is guaranteed across the full operating temperature range and defines the upper voltage limit imposed on protected circuitry during transient events. The SMA5J6.0-E3/61 achieves this performance with low incremental surge resistance, minimizing overshoot beyond the specified VC value.
Can the SMA5J6.0-E3/61 be used in bi-directional protection circuits?
No, the SMA5J6.0-E3/61 is strictly a unidirectional TVS diode and cannot be used for bi-directional surge suppression. Bi-directional operation requires a CA-suffixed part such as SMA5J6.0CA, which has symmetrical breakdown characteristics in both polarities. Using the SMA5J6.0-E3/61 in a bi-directional configuration would result in forward conduction and potential failure during negative transients. Always match the device polarity suffix (A = unidirectional, CA = bi-directional) to the circuit topology - SMA5J6.0-E3/61 is intended only for single-polarity DC line protection.
What is the thermal resistance profile of the SMA5J6.0-E3/61?
The SMA5J6.0-E3/61 has a typical junction-to-ambient thermal resistance (RθJA) of 80 °C/W and a junction-to-lead resistance (RθJL) of 25 °C/W, measured on the recommended 0.2" × 0.2" copper pad layout per terminal. These values assume standard JEDEC test conditions and define the device's ability to dissipate surge energy without exceeding its 150 °C maximum junction temperature. Proper PCB copper area and thermal vias are essential to maintain these ratings in real-world designs using the SMA5J6.0-E3/61.
