Product details
Overview
1.5SMC160AHM3_A/H from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a 160 V standoff voltage (VWM), 219 V maximum clamping voltage (VC) at 6.8 A peak pulse current, and 1500 W peak pulse power rating with 10/1000 µs waveform - optimized for automotive-grade surge immunity per AEC-Q101.
For engineers reviewing the 1.5SMC160AHM3_A/H datasheet, 1.5SMC160AHM3_A/H pinout, 1.5SMC160AHM3_A/H application, or 1.5SMC160AHM3_A/H equivalent, this device serves as a halogen-free, RoHS-compliant, surface-mount TVS for high-reliability DC bus, sensor interface, and ECU power rail protection where fast response (<1 ns), low incremental surge resistance, and MSL Level 1 reflow compatibility are critical.
Technical Context
The 1.5SMC160AHM3_A/H operates as a unidirectional avalanche diode with cathode-band polarity marking, leveraging glass-passivated junction technology for stable breakdown behavior and repeatable clamping under repetitive transients. Its thermal resistance (RθJA = 75 °C/W) and junction temperature limit (TJ = 150 °C) support operation on standard 8.0 mm × 8.0 mm copper pads without forced cooling.
It delivers 1500 W peak pulse power handling with a 10/1000 µs waveform at 0.01% duty cycle, and exhibits a temperature coefficient of VBR of +0.108 %/°C - enabling predictable voltage drift across automotive ambient ranges. The device is rated for 200 A non-repetitive forward surge current (IFSM) and maintains <1 μA reverse leakage at VWM = 136 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 136 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC bias margin for 12–48 V systems. |
| VBR @ IT = 1 mA | 152–168 V - Breakdown voltage range confirming tight tolerance (±5%) for consistent turn-on during transients. |
| VC @ IPPM = 6.8 A | 219 V - Clamped voltage under full-rated surge; determines protected circuit's maximum stress level. |
| PPPM | 1500 W - Peak pulse power dissipation capability with 10/1000 µs waveform; supports IEC 61000-4-5 Level 4 compliance. |
| IFSM | 200 A - Single half-sine surge current rating (8.3 ms); validates robustness against load-dump events in automotive 12 V systems. |
| TJ max | 150 °C - Maximum junction temperature; enables reliable operation in under-hood environments without derating below 125 °C ambient. |
| Package | SMC (DO-214AB) - Standardized 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 plastic case with matte tin-plated leads, UL 94 V-0 rated, MSL Level 1 compliant (peak reflow 260 °C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal (reverse-biased configuration) | Connected to protected line; conducts during positive transients when cathode is held at higher potential. |
| Cathode | Current exit terminal (marked with band) | Connected to ground or lower-potential reference; defines unidirectional conduction path and clamping polarity. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics per stress test requirements including HTOL, TCT, and ESD; supports PPAP documentation. |
| Halogen-free & RoHS-compliant | Meets JEDEC J-STD-609 Category 1a; eliminates brominated flame retardants and lead, cadmium, mercury, hexavalent chromium, PBB, PBDE. |
| 1500 W peak pulse power | Withstands IEC 61000-4-5 combination wave surges up to 4 kV/2 Ω without degradation; enables single-device protection for CAN, LIN, and power rails. |
| Low clamping ratio (VC/VBR ≈ 1.36) | Minimizes overvoltage overshoot during clamping; reduces risk of downstream IC latch-up or gate oxide damage in MOSFET drivers. |
| Fast response time (<1 ns) | Activates before most semiconductor switching transients propagate; protects sensitive analog front-ends and microcontroller I/O pins. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ160A | Same VWM (136 V), but lower PPPM = 400 W and higher VC = 259 V; SMA package (smaller footprint, lower thermal mass). | Limited to lower-energy transients (e.g., IEC 61000-4-2 ESD only); unsuitable for ISO 16750-2 load dump. | Select when board space is constrained and surge energy is ≤400 W; verify thermal derating for repeated events. |
| 1.5KE160A | Through-hole TO-204AA (DO-41); identical VWM/VC/PPPM, but slower response (~5 ns) and no AEC-Q101 qualification. | Not suitable for automated SMT production or automotive under-hood use; requires manual assembly and lacks automotive reliability validation. | Choose only for legacy through-hole designs or prototyping where reflow compatibility and automotive qualification are not required. |
Compared with SMAJ160A and 1.5KE160A, the 1.5SMC160AHM3_A/H uniquely combines AEC-Q101 qualification, 1500 W surge capacity, SMC surface-mount compatibility, and halogen-free construction - making it the only option qualified for volume production in automotive power modules and industrial control units requiring zero rework and full traceability.

FAQ
What is the clamping voltage of the 1.5SMC160AHM3_A/H at its rated peak pulse current?
The 1.5SMC160AHM3_A/H has a maximum clamping voltage (VC) of 219 V at 6.8 A peak pulse current (IPPM) with a 10/1000 µs waveform. This value is measured under standardized test conditions per JEDEC standards and defines the upper voltage limit imposed on protected circuits during surge events. The 1.5SMC160AHM3_A/H maintains this clamping performance across its full operating temperature range (-65 °C to +150 °C).
Is the 1.5SMC160AHM3_A/H qualified for automotive applications?
Yes, the 1.5SMC160AHM3_A/H is AEC-Q101 qualified, as indicated by the "HM3" suffix and "_A/H" revision code in its ordering designation. It has passed stress tests including high-temperature operating life (HTOL), temperature cycling (TCT), and electrostatic discharge (ESD), making it suitable for under-hood and body-control module applications. The 1.5SMC160AHM3_A/H is explicitly listed in Vishay's AEC-Q101 qualified product matrix for the 1.5SMC series.
What does the "HM3" suffix mean in 1.5SMC160AHM3_A/H?
The "HM3" suffix in 1.5SMC160AHM3_A/H denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. "H" indicates the halogen-free molding compound, "M3" confirms RoHS compliance per JEDEC J-STD-609, and the "_A/H" revision identifies the specific tape-and-reel packaging format (7-inch reel, 850 units). This distinguishes it from commercial-grade "E3" or "M3" variants lacking automotive qualification.
Can the 1.5SMC160AHM3_A/H be used in bidirectional protection circuits?
No, the 1.5SMC160AHM3_A/H is a unidirectional TVS diode, as confirmed by its part number ending in "A" (not "CA") and cathode-band marking. Bidirectional operation requires the "CA" suffix (e.g., 1.5SMC160CA). Using the 1.5SMC160AHM3_A/H in bidirectional configurations would result in forward conduction during negative transients, potentially causing failure. For symmetric surge protection, select the 1.5SMC160CHM3_A/H variant instead.
What is the thermal resistance and recommended pad layout for the 1.5SMC160AHM3_A/H?
The 1.5SMC160AHM3_A/H has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on minimum recommended 0.31″ × 0.31″ (8.0 mm × 8.0 mm) copper pads per terminal. This pad layout is specified in Vishay's datasheet Figure 6 and ensures adequate heat dissipation during repetitive pulse events. Reducing pad area increases RθJA, requiring derating of PPPM per Figure 2 in the datasheet.
