Overview
SMA5J5.0-E3/61 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor diode in DO-214AC (SMA) package, designed for primary overvoltage protection of DC power rails and signal lines. It features a 5.0 V stand-off voltage (VWM), 6.4–7.07 V breakdown voltage (VBR at 10 mA), 500 W peak pulse power (10/1000 µs), 54.3 V clamping voltage at 9.2 A peak current, and operates from –55 °C to +150 °C junction temperature.
For engineers reviewing the SMA5J5.0-E3/61 datasheet, SMA5J5.0-E3/61 pinout, SMA5J5.0-E3/61 application, or SMA5J5.0-E3/61 equivalent, key selection criteria include unidirectional polarity, low clamping ratio (VC/VWM = 10.86), AEC-Q101 qualification eligibility (via HE3 variant), RoHS-compliant matte tin plating, and compatibility with automated SMT placement on standard 0.2" × 0.2" copper pads.
Technical Context
This device functions as a voltage-clamped crowbar during transient events, leveraging an avalanche breakdown mechanism to shunt surge current away from protected circuitry. Its glass-passivated junction ensures stable VBR tolerance and long-term reliability under repetitive surge stress.
The SMA5J5.0-E3/61 exhibits 80 °C/W junction-to-ambient thermal resistance and 25 °C/W junction-to-lead resistance when mounted per recommended pad layout. It delivers 9.2 A peak pulse current (IPPM) at 500 W with a 10/1000 µs waveform and maintains ≤800 µA reverse leakage at VWM.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.0 V - Maximum continuous reverse operating voltage before conduction begins; defines upper limit of normal DC rail operation. |
| VBR (min/max) | 6.40 V / 7.07 V at 10 mA - Ensures reliable turn-on above system nominal voltage while avoiding false triggering during ripple or noise. |
| VC @ IPPM | 54.3 V at 9.2 A - Clamped voltage seen by downstream ICs during worst-case 500 W surge; critical for MOSFET/gate driver survivability. |
| PPPM | 500 W - Peak transient energy handling capacity using standardized 10/1000 µs waveform; validates robustness against IEC 61000-4-5 Level 4 surges. |
| IFSM | 40 A - Single half-sine surge rating (8.3 ms); supports protection against inductive switch-off transients in automotive power circuits. |
| TJ range | –55 °C to +150 °C - Enables deployment in under-hood automotive, industrial motor drives, and outdoor telecom equipment. |
Pinout & Package
Package: DO-214AC (SMA), surface-mount, unidirectional configuration with cathode band marking. Dimensions: 4.93 mm × 3.99 mm × 2.29 mm (L × W × H), 0.2" × 0.2" copper pad footprint per terminal.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection point | Connected to ground or return path; completes conduction loop during transient clamp event. |
| Cathode (banded end) | High-side connection point | Connected to protected line (e.g., 5 V rail); avalanche conduction initiates here when VAK exceeds VBR. |
Key Features
| Feature | Design Value |

Use Value: Fast response time (<1 ns) and 54.3 V clamping ensure downstream USB controller sees no more than 5.5 V during ESD event. |
Use Scenario: Front-end protection of 5 V DC input on small-cell base station power modules facing lightning-induced surges. IC Role / Device Role / Timing Role: Primary TVS on DC input rail, coordinated with upstream fuse and MOV to handle 10/1000 µs surges per IEC 61000-4-5. Use Value: 500 W rating and 40 A IFSM enable coordination with 1 A slow-blow fuse for selective clearing without device failure. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J5.0AHE3/61 | AEC-Q101 qualified; identical electrical specs and package; differs only in whisker test class (1A vs. 2A) and qualification documentation. | Required for automotive production programs mandating AEC-Q101 certification; otherwise electrically interchangeable. | Select SMA5J5.0AHE3/61 when automotive qualification is contractually required; SMA5J5.0-E3/61 suffices for industrial/commercial use. |
| SMCJ5.0A-E3/57T | Higher PPPM (1500 W), larger DO-214AB (SMC) package, same VWM/VBR, higher IPPM (39.4 A), slower thermal response due to larger die. | Better suited for high-energy surges (e.g., AC mains coupling) where PCB space allows larger footprint; not drop-in compatible. | Choose SMCJ5.0A-E3/57T only when 500 W is insufficient and board layout permits DO-214AB; avoid for space-constrained 5 V rail designs. |
Compared with SMA5J5.0AHE3/61, the SMA5J5.0-E3/61 offers identical protection performance without formal AEC-Q101 documentation-ideal for cost-sensitive industrial designs. Against SMCJ5.0A-E3/57T, it trades surge margin for compact DO-214AC footprint and faster thermal response, making it optimal for dense 5 V power domains.

FAQ
What is the polarity configuration of the SMA5J5.0-E3/61?
The SMA5J5.0-E3/61 is a unidirectional transient voltage suppressor diode. Its cathode is marked by a band on the DO-214AC (SMA) package body, and it conducts only when the cathode is at a higher potential than the anode-making it suitable for DC rail protection where polarity is fixed. This differs from bi-directional variants like SMA5J5.0CA, which lack polarity marking and conduct in both directions.
Does the SMA5J5.0-E3/61 meet automotive qualification standards?
The SMA5J5.0-E3/61 itself is RoHS-compliant and built on the same die and construction as the AEC-Q101-qualified SMA5J5.0AHE3/61 variant. While the E3 suffix denotes commercial-grade qualification, its material composition, thermal performance, and surge robustness align with automotive requirements-enabling use in non-safety-critical automotive subsystems where full AEC-Q101 documentation is not mandated.
What is the maximum clamping voltage of the SMA5J5.0-E3/61 under surge conditions?
The SMA5J5.0-E3/61 has a maximum clamping voltage (VC) of 54.3 V at its rated peak pulse current (IPPM) of 9.2 A, measured using the standard 10/1000 µs waveform. This value defines the highest voltage imposed on protected circuitry during a 500 W transient event and is critical for ensuring downstream 5 V ICs remain within absolute maximum ratings.
How does the SMA5J5.0-E3/61 compare to the SMAJ5.0A in terms of surge capability?
The SMA5J5.0-E3/61 delivers 500 W peak pulse power, whereas the older SMAJ5.0A is rated for only 400 W. This 25 % increase enables the SMA5J5.0-E3/61 to withstand higher-energy transients-such as those from ISO 7637-2 Pulse 5a-without degradation, while maintaining identical DO-214AC packaging and pinout for seamless upgrade in existing layouts.
What is the reverse leakage current specification for the SMA5J5.0-E3/61 at its stand-off voltage?
At its 5.0 V stand-off voltage (VWM) and 25 °C ambient temperature, the SMA5J5.0-E3/61 exhibits a maximum reverse leakage current (ID) of 800 µA. This low leakage ensures minimal quiescent power loss in always-on 5 V systems such as automotive body controllers or IoT sensor nodes operating from battery-backed rails.
