Product details
Overview
SMCJ5.0A-M3/57T from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode designed for primary overvoltage protection of DC power rails and signal lines. It features a 5.0 V stand-off voltage (VWM), 6.40–7.07 V breakdown voltage (VBR) at 10 mA, 1500 W peak pulse power (PPPM), and clamps transients to ≤9.2 V at 163 A (10/1000 µs waveform), making it suitable for protecting 5 V logic interfaces, USB power inputs, and automotive sensor supply lines.
For engineers reviewing the SMCJ5.0A-M3/57T datasheet, SMCJ5.0A-M3/57T pinout, SMCJ5.0A-M3/57T application, or SMCJ5.0A-M3/57T equivalent, key selection criteria include its 1500 W surge rating, low 9.2 V clamping voltage at rated current, halogen-free RoHS-compliant M3 termination, SMC (DO-214AB) package compatibility with automated placement, and AEC-Q101 qualification readiness via HM3 variants.
Technical Context
The SMCJ5.0A-M3/57T operates as a silicon avalanche diode that remains high-impedance below 5.0 V and rapidly transitions to low-impedance conduction above its 6.40–7.07 V breakdown threshold. Its glass-passivated junction ensures stable VBR tolerance and long-term reliability under repetitive surge stress.
It delivers 163 A peak pulse current (IPPM) under standardized 10/1000 µs waveform conditions when mounted on 8.0 mm × 8.0 mm copper pads, with thermal resistance of 75 °C/W (junction-to-ambient) and 15 °C/W (junction-to-lead), enabling effective heat dissipation in compact PCB layouts without heatsinks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.0 V - Maximum continuous reverse operating voltage before significant leakage; defines maximum DC rail voltage it can protect without conduction. |
| VBR min/max | 6.40 V / 7.07 V at 10 mA - Confirmed breakdown range ensuring reliable turn-on margin above 5 V rail while avoiding false triggering. |
| VC @ IPPM | ≤9.2 V at 163 A - Clamping voltage during full-rated surge; limits downstream IC stress to safe levels for 5 V systems. |
| PPPM | 1500 W - Peak pulse power handling per 10/1000 µs transient; supports IEC 61000-4-5 Level 4 surge immunity compliance. |
| ID @ VWM | 1000 µA max - Reverse leakage at 5.0 V; low enough to avoid loading sensitive 5 V reference or monitoring circuits. |
| Package | SMC (DO-214AB) - Industry-standard 2-pin surface-mount outline with 7.75 mm × 6.22 mm footprint and 2.62 mm height; optimized for reflow and wave soldering. |
| RoHS Status | Halogen-free, RoHS-compliant (M3 suffix) - Meets JEDEC JESD201 Class 2 whisker resistance and UL 94 V-0 flammability requirements. |
Pinout & Package
SMCJ5.0A-M3/57T uses the SMC (DO-214AB) package: a 2-terminal surface-mount device with cathode marked by a band on one end. The package has matte tin-plated leads, conforms to J-STD-002 and JESD22-B102 solderability standards, and meets MSL Level 1 (peak reflow temperature 260 °C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection point | Connected to ground or return path; completes conduction path during transient clamp event. |
| Cathode (banded end) | High-side connection point | Connected to protected line (e.g., +5 V rail); polarity-sensitive for unidirectional operation. |
Key Features
| Feature | Design Value |
|---|---|
| 1500 W peak pulse power | Enables robust protection against IEC 61000-4-5 surges up to 4 kV (line-earth) without derating in standard PCB layouts. |
| 9.2 V clamping voltage at 163 A | Keeps downstream 5 V logic ICs within absolute maximum ratings during worst-case transients. |
| Glass-passivated junction | Ensures stable VBR over temperature and lifetime, with <0.1 %/°C drift and no parameter shift after 1000 surge cycles. |
| MSL Level 1 rating | Allows unlimited floor life and single-reflow processing without baking, reducing manufacturing cost and complexity. |
| Automated placement compatible | Standard SMC footprint and lead geometry support high-speed pick-and-place at >25,000 CPH with >99.99 % placement yield. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A-M3 | Lower PPPM (400 W), smaller SMA package (DO-214AC), higher RθJA (110 °C/W) | Restricted to lower-energy transients; unsuitable for IEC 61000-4-5 Level 4 or automotive load dump | Select only for space-constrained consumer boards where 1500 W rating is unnecessary. |
| SMCJ5.0A-E3/57T | Same electrical specs and SMC package, but RoHS-compliant commercial grade (E3) instead of halogen-free (M3) | No difference in circuit function or layout; differs only in material compliance and whisker resistance class | Choose E3 for non-automotive industrial use where halogen-free requirement is not mandated. |
Compared with SMAJ5.0A-M3, SMCJ5.0A-M3/57T provides 3.75× higher surge power and superior thermal performance; versus SMCJ5.0A-E3/57T, it adds halogen-free compliance and JESD201 Class 2 whisker resistance-critical for automotive-tier-1 production and export-regulated markets.

FAQ
What is the maximum clamping voltage of the SMCJ5.0A-M3/57T under full-rated surge conditions?
The SMCJ5.0A-M3/57T clamps to a maximum of 9.2 V when subjected to its rated 163 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured with the device mounted on 8.0 mm × 8.0 mm copper pads per JEDEC test conditions and ensures downstream 5 V ICs remain within safe operating limits during surge events.
Is the SMCJ5.0A-M3/57T suitable for automotive applications requiring AEC-Q101 qualification?
The SMCJ5.0A-M3/57T itself is halogen-free and RoHS-compliant but not AEC-Q101 qualified. However, Vishay offers the functionally identical SMCJ5.0AHM3_A/H variant, which carries the HM3 suffix and full AEC-Q101 qualification-making it the direct drop-in replacement for automotive ECUs and ADAS modules requiring certified reliability.
How does the SMCJ5.0A-M3/57T differ from the SMAJ5.0A-M3 in terms of surge handling capability?
The SMCJ5.0A-M3/57T delivers 1500 W peak pulse power (PPPM), whereas the SMAJ5.0A-M3 is rated for only 400 W. This 3.75× higher energy absorption stems from the larger SMC (DO-214AB) package's lower thermal resistance (75 °C/W vs. 110 °C/W) and optimized chip geometry-enabling SMCJ5.0A-M3/57T to handle IEC 61000-4-5 Level 4 surges that would fail the SMAJ device.
What is the reverse leakage current specification for the SMCJ5.0A-M3/57T at its 5.0 V stand-off voltage?
At the rated 5.0 V stand-off voltage (VWM), the SMCJ5.0A-M3/57T exhibits a maximum reverse leakage current (ID) of 1000 µA at 25 °C. This low leakage ensures minimal impact on power rail efficiency and avoids false triggering in precision 5 V monitoring circuits, such as those used in battery-powered sensor nodes.
Can the SMCJ5.0A-M3/57T be used in bidirectional configurations?
No-the SMCJ5.0A-M3/57T is a unidirectional TVS diode, identifiable by its cathode band marking. For bidirectional operation, Vishay specifies the SMCJ5.0CA-M3 variant, which has symmetric breakdown characteristics in both polarities and no polarity marking. Using SMCJ5.0A-M3/57T in reverse-biased AC applications risks permanent failure due to forward conduction during negative half-cycles.
