Product details
Overview
SMA5J5.0A-M3/61 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for primary overvoltage protection of DC power rails and signal lines. It features 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 pulse current, and operates from –55 °C to +150 °C junction temperature - used in automotive sensor interface protection.
For engineers reviewing the SMA5J5.0A-M3/61 datasheet, SMA5J5.0A-M3/61 pinout, SMA5J5.0A-M3/61 application, or SMA5J5.0A-M3/61 equivalent, key selection criteria include clamping performance under 10/1000 µs surge, unidirectional polarity marking, halogen-free RoHS compliance (M3 suffix), and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode employs a glass-passivated silicon junction optimized for fast response (<1 ns) to ESD and lightning-induced transients. Its low incremental surge resistance ensures minimal voltage overshoot during high-current surges up to 9.2 A (IPPM), while maintaining stable clamping at VC = 54.3 V under standardized 10/1000 µs waveform conditions.
The device is rated for 40 A non-repetitive forward surge current (IFSM, 8.3 ms half-sine), supports MSL Level 1 moisture sensitivity, and achieves thermal resistance of 25 °C/W junction-to-lead - enabling reliable operation in compact, thermally constrained PCB layouts without forced cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.0 V - maximum continuous reverse operating voltage before clamping begins; defines safe DC rail margin for 5 V systems. |
| VBR min/max | 6.4 V / 7.07 V at 10 mA - verified breakdown threshold ensuring predictable turn-on during overvoltage events. |
| VC @ IPPM | 54.3 V at 9.2 A - clamping voltage limits downstream IC stress during 10/1000 µs surge; critical for protecting 3.3 V/5 V logic interfaces. |
| PPPM | 500 W - peak pulse power handling capacity per 10/1000 µs waveform; determines survivability against IEC 61000-4-5 Level 4 surges. |
| TJ max | +150 °C - maximum junction temperature rating enables use in under-hood automotive environments and industrial enclosures. |
| ID @ VWM | 800 µA - reverse leakage at stand-off voltage; low enough to avoid measurable power loss or signal distortion in battery-powered sensors. |
Pinout & Package

FAQ
What is the clamping voltage of the SMA5J5.0A-M3/61 under standard 10/1000 µs surge conditions?
The SMA5J5.0A-M3/61 has a maximum clamping voltage (VC) of 54.3 V at 9.2 A peak pulse current (IPPM) under the standardized 10/1000 µs waveform. This value is measured with the device mounted on 5.0 mm × 5.0 mm copper pads per JEDEC guidelines and defines the upper voltage limit imposed on protected circuitry during surge events. The SMA5J5.0A-M3/61 maintains this clamping performance across its full operating temperature range.
Does the SMA5J5.0A-M3/61 meet automotive qualification standards?
No, the SMA5J5.0A-M3/61 is halogen-free and RoHS-compliant but not AEC-Q101 qualified. For automotive applications requiring formal qualification, Vishay offers the SMA5J5.0AHE3_A/H or SMA5J5.0AHM3_A/H variants. The SMA5J5.0A-M3/61 is rated for industrial and consumer use with operating junction temperature from –55 °C to +150 °C and meets MSL Level 1 for SMT processing.
How does the M3 suffix differ from E3 in the SMA5J5.0A-M3/61 part number?
The M3 suffix indicates halogen-free, RoHS-compliant construction, whereas E3 denotes RoHS-compliant but standard brominated flame-retardant molding compound. Both share identical electrical specifications, thermal performance, and packaging dimensions. The SMA5J5.0A-M3/61 satisfies stricter environmental mandates such as IEC 61249-2-21 and is preferred for green electronics initiatives without sacrificing surge capability or reliability.
What is the reverse leakage current of the SMA5J5.0A-M3/61 at its 5.0 V stand-off voltage?
The SMA5J5.0A-M3/61 exhibits a maximum reverse leakage current (ID) of 800 µA at its rated stand-off voltage (VWM) of 5.0 V and ambient temperature of 25 °C. This low leakage ensures minimal standby power loss in battery-operated systems and avoids false triggering in high-impedance sensing nodes. Leakage remains within specification up to +125 °C per derating curves in the official Vishay datasheet.
Can the SMA5J5.0A-M3/61 be used in bidirectional protection applications?
No - the SMA5J5.0A-M3/61 is strictly unidirectional, as indicated by the "A" suffix and cathode band marking. For bidirectional transient suppression, Vishay specifies parts with the "CA" suffix (e.g., SMA5J5.0CA). Using the SMA5J5.0A-M3/61 in reverse-biased AC or differential signal paths would result in forward conduction and potential failure; correct polarity orientation is mandatory for proper operation.
