Product details
Overview
1.5SMC510A-M3/57T from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for high-energy surge protection in power and signal lines. It features a 510 V breakdown voltage (VBR = 485–535 V), 1500 W peak pulse power (10/1000 µs), clamping voltage of 698 V at 2.15 A, and operates across –65 °C to +150 °C junction temperature. It is used to protect MOSFETs, DC-DC converters, and industrial power supplies against lightning-induced transients and inductive switching spikes.
For engineers reviewing the 1.5SMC510A-M3/57T datasheet, 1.5SMC510A-M3/57T pinout, 1.5SMC510A-M3/57T application, or 1.5SMC510A-M3/57T equivalent, this page delivers verified electrical parameters, SMC (DO-214AB) package details, polarity marking guidance, real-world clamping behavior, and qualified automotive-grade alternatives with documented differences in qualification status and leakage performance.
Technical Context
The 1.5SMC510A-M3/57T employs a glass-passivated silicon junction optimized for fast response (<1 ps) to transient overvoltages and low incremental surge resistance. Its unidirectional configuration provides asymmetric conduction-blocking reverse current until breakdown, then clamping forward surges via avalanche action.
Rated for 1500 W peak pulse power under 10/1000 µs waveform and 200 A non-repetitive forward surge (8.3 ms half-sine), it maintains stable operation up to 150 °C junction temperature with thermal resistance RθJA = 75 °C/W on standard 8.0 mm × 8.0 mm copper pads. The M3 suffix confirms halogen-free, RoHS-compliant construction meeting JESD201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 485 V / 535 V - Ensures reliable avalanche initiation above normal operating voltage while avoiding false triggering. |
| VWM | 434 V - Maximum continuous reverse stand-off voltage; system must operate ≤434 V to prevent leakage or degradation. |
| VC @ IPPM | 698 V - Clamped voltage during 2.15 A 10/1000 µs surge; defines worst-case voltage seen by protected downstream circuitry. |
| PPPM | 1500 W - Peak transient energy absorption capability; determines survivability against lightning or EFT events per IEC 61000-4-5. |
| IPPM | 2.15 A - Peak pulse current corresponding to VC; used with PCB trace impedance to estimate actual clamping margin. |
| TJ max | +150 °C - Enables use in under-hood automotive or high-ambient industrial environments without derating. |
| RθJA | 75 °C/W - Thermal resistance on standard pad layout; informs heatsinking requirements for repetitive surge duty cycles. |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, molded plastic case with matte tin-plated leads solderable per J-STD-002 and JESD22-B102. Polarity indicated by cathode band; anode and cathode terminals are axially oriented along the body length.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | High-side connection point for unidirectional clamping | Connected to protected line; conducts avalanche current toward ground when transient exceeds VBR. |
| Anode (non-banded end) | Low-side reference terminal | Typically tied to system ground or return path; completes clamping loop during overvoltage event. |
Key Features
| Feature | Design Value |
|---|---|
| 1500 W peak pulse power (10/1000 µs) | Supports IEC 61000-4-5 Level 4 (4 kV) surge immunity in industrial power inputs without external series impedance. |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients, improving protection margin for sensitive gate drivers. |
| Halogen-free, RoHS-compliant (M3 suffix) | Meets IPC-1752A material declaration requirements and EU environmental compliance for export-controlled systems. |
| MSL Level 1, 260 °C reflow compatible | Enables single-pass lead-free reflow assembly without moisture sensitivity concerns or baking preconditioning. |
| AEC-Q101 qualified variant available | HM3 suffix versions support automotive powertrain and body electronics requiring stress-tested reliability validation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ510A-E3/57T | Same VBR range (485–535 V) but lower PPPM = 400 W; SMA package (smaller footprint, higher RθJA). | Limited to lower-energy transients (IEC 61000-4-5 Level 2); unsuitable for 48 V industrial mains coupling. | Select only where space constraints outweigh surge margin needs and ambient temperature remains <85 °C. |
| 1.5SMC510AHM3_B/57T | Identical electrical specs; HM3 suffix adds AEC-Q101 qualification and extended temperature validation (–55 °C to +150 °C). | Required for automotive power modules, engine control units, and safety-critical subsystems per OEM specifications. | Choose when automotive qualification, enhanced process controls, and full traceability are mandatory-not just electrical equivalence. |
Compared with 1.5SMC510A-M3/57T, SMAJ510A-E3/57T trades surge robustness for compactness, while 1.5SMC510AHM3_B/57T delivers identical clamping performance plus automotive-grade reliability validation-making it the preferred choice for vehicle electrification designs where qualification evidence is contractually required.

FAQ
What is the maximum clamping voltage of the 1.5SMC510A-M3/57T under rated surge conditions?
The 1.5SMC510A-M3/57T exhibits a maximum clamping voltage (VC) of 698 V when subjected to its rated peak pulse current of 2.15 A using the standardized 10/1000 µs waveform. This value is measured at TA = 25 °C on recommended 8.0 mm × 8.0 mm copper pads and defines the upper voltage limit imposed on protected circuitry during surge events. The 1.5SMC510A-M3/57T maintains this clamping performance across its full operating temperature range.
Is the 1.5SMC510A-M3/57T suitable for automotive applications?
The 1.5SMC510A-M3/57T itself is commercial-grade and not AEC-Q101 qualified; however, its direct variant 1.5SMC510AHM3_B/57T carries full AEC-Q101 qualification for automotive use. Engineers deploying the 1.5SMC510A-M3/57T in automotive contexts must validate system-level reliability independently, as the 1.5SMC510A-M3/57T lacks the stress-test documentation required by Tier 1 suppliers. For production automotive designs, the HM3-suffix version is the approved 1.5SMC510A-M3/57T derivative.
How does the M3 suffix affect the 1.5SMC510A-M3/57T's compliance profile?
The M3 suffix on the 1.5SMC510A-M3/57T indicates halogen-free, RoHS-compliant construction meeting IPC-1752A material declarations and JESD201 Class 2 whisker resistance. Unlike E3-suffix parts, M3 devices eliminate brominated flame retardants while retaining UL 94 V-0 flammability rating and 260 °C lead-free reflow compatibility. The 1.5SMC510A-M3/57T is certified for commercial-grade environmental compliance-not automotive or military standards.
What is the reverse leakage current of the 1.5SMC510A-M3/57T at its maximum working voltage?
At its maximum reverse stand-off voltage (VWM) of 434 V and TA = 25 °C, the 1.5SMC510A-M3/57T specifies a maximum reverse leakage current (ID) of 1.0 µA. This ultra-low leakage ensures minimal power loss and thermal drift in high-impedance bias networks or precision voltage monitoring circuits. The 1.5SMC510A-M3/57T maintains this specification across its full operating temperature range, with leakage increasing predictably per datasheet derating curves.
Can the 1.5SMC510A-M3/57T be used in bidirectional configurations?
No-the 1.5SMC510A-M3/57T is strictly unidirectional, as confirmed by its "A" suffix and cathode-band marking. Bidirectional operation requires the "CA" suffix (e.g., 1.5SMC510CA), which integrates two opposing diodes in series. Using the 1.5SMC510A-M3/57T in reverse-biased mode risks permanent junction damage above 434 V. For AC-coupled or floating-line protection, select the CA variant or pair discrete unidirectional units with appropriate polarity orientation.
