Product details
Overview
1.5SMC510AHM3_A/I 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 standoff voltage (VWM), 535 V maximum breakdown voltage (VBR), 1500 W peak pulse power (10/1000 μs), clamps to 698 V at 2.15 A, and operates across -65 °C to +150 °C - deployed in automotive power supply rails and industrial motor drive I/O protection.
For engineers reviewing the 1.5SMC510AHM3_A/I datasheet, 1.5SMC510AHM3_A/I pinout, 1.5SMC510AHM3_A/I application, or 1.5SMC510AHM3_A/I equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, SMC (DO-214AB) package details, clamping performance under lightning-surge conditions, and direct alternatives with documented voltage and surge-current trade-offs.
Technical Context
This TVS diode uses a glass-passivated silicon junction optimized for fast response (<1 ns) to transient overvoltages and low incremental surge resistance to maintain tight clamping during 10/1000 μs surges. Its unidirectional polarity enables integration into DC-biased circuits where reverse conduction must be blocked.
The device is rated for 1500 W peak pulse power at 25 °C, derated linearly above TA = 25 °C per Figure 2, and supports 200 A non-repetitive forward surge current (8.3 ms half-sine). Thermal resistance is 75 °C/W junction-to-ambient on standard 8.0 mm × 8.0 mm copper pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 434 V - Maximum continuous reverse voltage before clamping begins; defines safe operating margin below breakdown. |
| VBR (Breakdown) | 485–535 V at 1 mA - Confirmed breakdown range ensures reliable turn-on during transients without premature conduction. |
| VC (Clamping) | 698 V at IPPM = 2.15 A - Measured clamping voltage limits downstream component stress during full-rated surge. |
| PPPM | 1500 W (10/1000 μs) - Sustains high-energy lightning-induced surges per IEC 61000-4-5 Level 4 without failure. |
| TJ max. | +150 °C - Enables use in under-hood automotive environments and enclosed industrial enclosures. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD robustness. |
| Package | SMC (DO-214AB) - Surface-mount outline with 7.75 mm × 6.22 mm footprint and 2.62 mm height; compatible with automated pick-and-place. |
Pinout & Package
Package: SMC (DO-214AB), molded epoxy case with matte tin-plated leads; cathode indicated by band on one end; compliant with UL 94 V-0 and J-STD-002 solderability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / Surge return path | Connected to system ground or low-side reference; carries full surge current during clamping. |
| Cathode | Protected line connection / Surge sink | Connected to line being protected (e.g., 48 V rail); blocks reverse leakage until breakdown threshold is exceeded. |
Key Features
| Feature | Design Value |
|---|---|
| 1500 W peak pulse rating | Withstands IEC 61000-4-5 4th-level surges (4 kV/2 Ω) on 48 V systems without degradation. |
| Glass-passivated junction | Ensures stable VBR over lifetime and immunity to humidity-induced parameter drift in harsh environments. |
| AEC-Q101 qualification | Validated for automotive power modules, battery management systems, and ADAS sensor interfaces. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., inductive switch-off in solenoid drivers). |
| MSL Level 1 (260 °C) | Compatible with lead-free reflow profiles without preconditioning; eliminates moisture-related popcorning. |
Applications
| Automotive Power Rail Protection | Industrial Motor Drive I/O |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ510A | Same VWM (434 V) and VC (698 V), but lower PPPM (600 W) and smaller SMB package (DO-214AA). | Limited to lower-energy surges (IEC 61000-4-5 Level 2); unsuitable for automotive load dump or industrial 4 kV testing. | Select when board space is constrained and surge threat level is ≤600 W; verify thermal margin on 5.3 mm × 4.6 mm pads. |
| 1.5KE510A | Through-hole TO-204AE (DO-201AE); identical VWM, VBR, and VC, but higher RθJA (60 °C/W) and no AEC-Q101 qualification. | Not suitable for automated SMT production or automotive qualification requirements; requires wave soldering. | Choose only for legacy through-hole designs or prototyping where rework tolerance outweighs volume manufacturing needs. |
Compared with 1.5SMC510AHM3_A/I, SMBJ510A trades surge capacity and qualification for compact size, while 1.5KE510A retains electrical equivalence but sacrifices SMT compatibility and automotive reliability validation - making 1.5SMC510AHM3_A/I the optimal choice for production-grade automotive and industrial SMT systems requiring 1500 W clamping and AEC-Q101 assurance.

FAQ
What is the clamping voltage of the 1.5SMC510AHM3_A/I at its rated peak pulse current?
The 1.5SMC510AHM3_A/I clamps to 698 V at its specified peak pulse current of 2.15 A (10/1000 μs waveform). This value is measured under standardized test conditions with the device mounted on 8.0 mm × 8.0 mm copper pads and represents the maximum voltage seen downstream during full-rated surge events - critical for ensuring connected ICs remain within absolute maximum ratings.
Is the 1.5SMC510AHM3_A/I qualified for automotive applications?
Yes, the 1.5SMC510AHM3_A/I is AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "HM3_A" and documentation revision 09-Mar-2026. This qualification covers stress tests including temperature cycling, high-temperature reverse bias, and ESD, making the 1.5SMC510AHM3_A/I suitable for under-hood ECUs, battery management systems, and ADAS sensor interfaces where reliability under thermal and electrical stress is mandatory.
What does the "HM3" suffix mean in 1.5SMC510AHM3_A/I?
The "HM3" suffix in 1.5SMC510AHM3_A/I indicates halogen-free, RoHS-compliant construction with AEC-Q101 qualification. The "H" denotes 7-inch tape-and-reel packaging (850 units per reel), and "I" specifies 13-inch tape-and-reel (3500 units per reel). This distinguishes it from commercial-grade "E3" or "M3" variants and confirms compliance with automotive material and reliability standards.
Can the 1.5SMC510AHM3_A/I be used in bidirectional configurations?
No, the 1.5SMC510AHM3_A/I is a unidirectional TVS diode, as indicated by the "A" suffix and absence of "CA" in the part number. Bidirectional versions (e.g., 1.5SMC510CA) are available separately. Using the unidirectional 1.5SMC510AHM3_A/I in AC or floating applications would result in unintended forward conduction during negative half-cycles - always match polarity to circuit topology.
What is the thermal resistance of the 1.5SMC510AHM3_A/I, and how does it affect layout?
The 1.5SMC510AHM3_A/I has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on minimum recommended 8.0 mm × 8.0 mm copper pads. To maintain safe operation at full 1500 W surge rating, PCB layout must provide adequate copper area and avoid thermal bottlenecks - undersized pads or internal layer isolation will increase junction temperature and reduce surge endurance.
