Product details
Overview
1.5SMC10AHM3/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection in power rails and signal lines. It features a 10 V standoff voltage (VWM), 14.5 V clamping voltage (VC) at 103 A peak pulse current, and 1500 W peak pulse power capability with a 10/1000 μs waveform - suitable for automotive power supply input protection against load dump and ESD.
For engineers reviewing the 1.5SMC10AHM3/H datasheet, 1.5SMC10AHM3/H pinout, 1.5SMC10AHM3/H application, or 1.5SMC10AHM3/H equivalent, this device is evaluated for high-reliability transient suppression in AEC-Q101-compliant automotive systems, industrial DC inputs, and sensor interface protection where low clamping voltage and fast response (<1 ns) are critical.
Technical Context
The 1.5SMC10AHM3/H operates as a unidirectional avalanche diode, conducting only when reverse voltage exceeds its breakdown threshold (9.5–10.5 V at 10 mA). Its glass-passivated junction ensures stable leakage performance and robust surge handling under repetitive transients.
It is rated for 200 A non-repetitive forward surge current (8.3 ms half-sine), operates from –65 °C to +150 °C, and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak - confirming suitability for automated SMT assembly in harsh-environment applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 8.55 V - maximum continuous reverse operating voltage before conduction begins; defines safe DC operating margin. |
| VBR (Breakdown) | 9.5–10.5 V at 10 mA - precise avalanche initiation range ensuring predictable turn-on during transients. |
| VC (Clamping) | 14.5 V at 103 A (10/1000 μs) - limits downstream voltage stress to protect 12 V-rated ICs and MOSFETs. |
| PPPM | 1500 W - peak transient energy absorption capacity under standardized surge waveform. |
| IPPM | 103 A - maximum non-repetitive surge current it safely clamps without failure. |
| TJ max | +150 °C - enables operation in under-hood automotive environments and high-ambient industrial enclosures. |
| RθJA | 75 °C/W - thermal resistance from junction to ambient on standard 8 mm × 8 mm copper pads; informs heatsinking needs. |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, halogen-free, RoHS-compliant, AEC-Q101 qualified. Cathode indicated by banded end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / Reverse voltage reference | Connected to system ground or lower-potential rail; defines polarity-sensitive placement in unidirectional configuration. |
| Cathode | Avalanche conduction terminal | Banded end; connected to protected line (e.g., 12 V supply); conducts surge current to ground when VREV > VBR. |
Key Features
| Feature | Design Value |
|---|---|
| 1500 W peak pulse power | Enables single-device protection against ISO 7637-2 Pulse 1, 2a, and 5a load-dump events in 12 V automotive systems. |
| 14.5 V clamping at 103 A | Keeps protected circuitry below 16 V absolute maximum rating of common automotive MCUs and gate drivers. |
| AEC-Q101 qualified (HM3 suffix) | Validated for automotive-grade reliability including temperature cycling, HTRB, and surge endurance per stress test plan. |
| MSL Level 1, 260 °C peak reflow | Supports lead-free reflow soldering without preconditioning; eliminates moisture-related popcorning risk. |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (e.g., ESD ±30 kV contact discharge), improving protection margin. |
Applications
| Automotive Power Input Protection | Industrial DC Power Rail Clamping |
|---|---|
Use Scenario: Protecting vehicle body control module (BCM) 12 V input from load dump transients up to 35 V/100 ms. IC Role / Device Role / Timing Role: Unidirectional TVS placed between battery rail and input filter capacitor. Use Value: Clamps peak voltage to ≤14.5 V during 103 A surge, preventing damage to upstream DC-DC converter and MCU power pins. |
Use Scenario: Safeguarding programmable logic controller (PLC) 24 V DC input against switching surges from solenoid coils. IC Role / Device Role / Timing Role: Primary overvoltage clamp on field-side power entry point, upstream of EMI filter. Use Value: Absorbs 1500 W transient energy within <1 ns, maintaining downstream voltage below 16 V for 24 V-rated I/O drivers. |
| Sensor Signal Line Protection | Automotive CAN Bus Power Line |
Use Scenario: Shielding analog output of engine coolant temperature sensor from coupled transients on harness wiring. IC Role / Device Role / Timing Role: Low-capacitance TVS on sensor VOUT line, grounded via short trace. Use Value: Limits induced voltage spikes to <15 V while adding <0.5 pF parasitic capacitance - preserving 0–5 V signal integrity. |
Use Scenario: Reinforcing power-supply resilience of CAN transceiver modules exposed to battery rail disturbances. IC Role / Device Role / Timing Role: Secondary clamping device on VCC pin of CAN FD transceiver (e.g., TCAN1042). Use Value: Complements internal protection by reducing clamping voltage from ~25 V to 14.5 V, extending transceiver lifetime under repeated surges. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A | Same 10 V VWM, but 400 W PPPM and 32.4 V VC at 12.3 A - significantly lower surge capacity and higher clamping. | Not suitable for automotive load dump; limited to low-energy ESD or microsecond-level transients in consumer electronics. | Select only if space-constrained SOD-123 footprint is mandatory and surge energy is <200 W. |
| 1.5KE10A | Through-hole TO-204AA (DO-41); identical VWM/VBR/VC specs but 1500 W rating requires larger PCB area and manual assembly. | Used where legacy through-hole manufacturing remains, or where thermal mass improves long-duration surge handling. | Choose when board-level rework tolerance or higher thermal inertia is prioritized over SMT automation. |

FAQ
What is the clamping voltage of the 1.5SMC10AHM3/H under a 10/1000 μs surge?
The 1.5SMC10AHM3/H has a maximum clamping voltage (VC) of 14.5 V when subjected to a 10/1000 μs waveform at its rated peak pulse current of 103 A. This value is measured per Figure 1 and Table on page 2 of Vishay document 88303 and ensures reliable protection of 12 V nominal circuits without exceeding typical IC absolute maximum ratings.
Is the 1.5SMC10AHM3/H AEC-Q101 qualified?
Yes, the 1.5SMC10AHM3/H is AEC-Q101 qualified. The "HM3" suffix denotes halogen-free, RoHS-compliant construction with full AEC-Q101 stress testing - including temperature cycling, high-temperature reverse bias (HTRB), and surge endurance - as confirmed in the Vishay 1.5SMC Series datasheet revision 09-Mar-2026, section "Ordering Information" and "Mechanical Data".
What does the "H" in 1.5SMC10AHM3/H indicate?
The "H" in 1.5SMC10AHM3/H specifies the tape-and-reel packaging format: 7-inch diameter plastic tape and reel containing 850 units. This is defined in Vishay's ordering information table (page 3, document 88303), where "H" corresponds to the delivery mode code for standard-volume SMT reels.
Can the 1.5SMC10AHM3/H be used in bidirectional configurations?
No, the 1.5SMC10AHM3/H is a unidirectional TVS diode. Bidirectional variants use the "CA" suffix (e.g., 1.5SMC10CA). The "A" in 1.5SMC10AHM3/H explicitly denotes unidirectional polarity, with cathode marked by a band - using it in bidirectional applications would result in forward conduction during negative transients and potential failure.
What is the maximum operating junction temperature for the 1.5SMC10AHM3/H?
The 1.5SMC10AHM3/H has a maximum operating junction temperature (TJ) of +150 °C, as specified in the "Maximum Ratings" table (page 1, document 88303). This rating supports deployment in under-hood automotive locations and enclosed industrial power supplies where ambient temperatures exceed 105 °C.
