Product details
Overview
1.5SMC160AHM3/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a 160 V standoff voltage (VWM), 179 V minimum breakdown voltage (VBR), 219 V maximum clamping voltage (VC) at 6.8 A peak pulse current, and 1500 W peak pulse power capability with a 10/1000 μs waveform - deployed in automotive ECUs, industrial motor drives, and telecom power supplies.
For engineers reviewing the 1.5SMC160AHM3/H datasheet, 1.5SMC160AHM3/H pinout, 1.5SMC160AHM3/H application, or 1.5SMC160AHM3/H equivalent, key selection criteria include clamping performance under 10/1000 μs transients, AEC-Q101 qualification status, thermal resistance (RθJA = 75 °C/W), and halogen-free RoHS compliance per HM3 suffix.
Technical Context
This device operates as a unidirectional avalanche diode, leveraging glass-passivated junction technology to achieve fast response time (<1 ns) and low incremental surge resistance. Its clamping behavior is defined by the 10/1000 μs waveform standard per IEC 61000-4-5, with derating applied above TA = 25 °C per Figure 2 of the datasheet.
The 1.5SMC160AHM3/H is rated for TJ = –65 °C to +150 °C operation and mounts on 8.0 mm × 8.0 mm copper pads per JEDEC DO-214AB (SMC) footprint. It meets JESD201 Class 2 whisker resistance and MSL Level 1 reflow profile (peak 260 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 136 V - Maximum continuous reverse operating voltage before significant leakage; defines safe DC/AC bias margin. |
| VBR (Breakdown Voltage) | 152–168 V at IT = 1 mA - Voltage at which avalanche conduction begins; ensures predictable turn-on during transients. |
| VC (Clamping Voltage) | 219 V at IPPM = 6.8 A - Peak voltage seen by protected circuit during 10/1000 μs surge; determines downstream component stress. |
| PPPM (Peak Pulse Power) | 1500 W - Sustained transient energy absorption capacity; enables protection against lightning-induced surges (IEC 61000-4-5 Level 4). |
| ID (Reverse Leakage) | 1.0 μA at VWM - Minimal standby current; preserves efficiency in always-on power rails and sensor interfaces. |
| TJ max. | +150 °C - Maximum junction temperature rating; supports operation in under-hood automotive and high-ambient industrial environments. |
| Package | SMC (DO-214AB) - Standardized surface-mount outline with 7.75 mm × 6.22 mm body and 2.62 mm height; compatible with automated pick-and-place. |
Pinout & Package
Package: SMC (DO-214AB), molded epoxy case meeting UL 94 V-0 flammability rating; matte tin-plated leads solderable per J-STD-002 and JESD 22-B102; cathode indicated by band marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal (unidirectional mode) | Connected to protected line side; reverse-biased during normal operation; conducts during positive transients relative to cathode. |
| Cathode | Current exit terminal (unidirectional mode) | Connected to ground or low-impedance return path; establishes polarity-sensitive clamping action; marked with band. |
Key Features
| Feature | Design Value |
|---|---|

| 1500 W peak pulse power (10/1000 μs) | Supports IEC 61000-4-5 Level 4 surge immunity (4 kV line-to-ground) in compact SMC package - eliminates need for larger DO-214AA or axial devices. |
| Low RθJA = 75 °C/W | Enables stable thermal performance on standard PCB copper pads without heatsinking - critical for space-constrained modules. |
| Glass-passivated junction | Ensures long-term stability of VBR and leakage under thermal/humidity stress; improves consistency across production lots and lifetime. |
Applications
| Automotive Power Rail Protection | Industrial Motor Drive Control |
|---|---|

IC Role / Device Role / Timing Role: Unidirectional TVS connected from output rail to system ground to absorb repetitive 10/1000 μs pulses. Use Value: 0.01 % duty cycle rating allows sustained protection without thermal runaway; 1.0 μA leakage avoids loading precision voltage references. |
Use Scenario: Input-stage protection for polyphase metering SoCs operating from 230 VAC-derived 12 V rails in utility substations. IC Role / Device Role / Timing Role: Clamps induced surges from nearby lightning strikes or grid switching events on isolated DC supply lines. Use Value: AEC-Q101 qualification ensures reliability over 15-year field life; halogen-free construction meets EU RoHS and REACH mandates. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ160A-E3/57T | Same VWM (136 V) and VC (219 V), but lower PPPM (400 W); SMA package (smaller footprint, higher RθJA = 110 °C/W). | Limited to lower-energy transients; unsuitable for IEC 61000-4-5 Level 4; preferred where board space is constrained and surge severity is moderate. | Select when cost or size outweighs surge robustness; verify thermal margin under repeated 10/1000 μs events. |
| 1.5KE160A | Through-hole TO-204AA (DO-41); identical electrical specs but larger footprint and manual assembly requirement; no AEC-Q101 or halogen-free certification. | Used in legacy industrial designs or prototyping; lacks automotive qualification and modern environmental compliance. | Choose only for backward compatibility or non-automotive repair scenarios; not recommended for new AEC-Q101 or RoHS-mandated designs. |

FAQ
What is the clamping voltage of the 1.5SMC160AHM3/H under a 10/1000 μs surge?
The 1.5SMC160AHM3/H has a maximum clamping voltage (VC) of 219 V at a peak pulse current (IPPM) of 6.8 A with a 10/1000 μs waveform. This value is measured per Figure 1 and Table on page 2 of the Vishay datasheet 88303 and defines the upper voltage limit imposed on protected circuitry during standardized surge events.
Is the 1.5SMC160AHM3/H qualified for automotive applications?
Yes, the 1.5SMC160AHM3/H is AEC-Q101 qualified, as confirmed by its HM3 suffix and documentation in the Vishay 1.5SMC Series datasheet (Rev. 09-Mar-2026). It undergoes rigorous stress testing including temperature cycling, high-temperature reverse bias, and ESD, making it suitable for under-hood and cabin electronics.
What does the 'HM3' suffix indicate for the 1.5SMC160AHM3/H?
The 'HM3' suffix on the 1.5SMC160AHM3/H denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. It replaces lead-based finishes with matte tin plating and uses bromine-free molding compounds - satisfying both environmental regulations and automotive reliability standards.
What is the thermal resistance of the 1.5SMC160AHM3/H?
The 1.5SMC160AHM3/H has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 8.0 mm × 8.0 mm copper pads, per the Thermal Characteristics table on page 3 of the Vishay datasheet. This value assumes JEDEC-standard PCB layout and enables accurate thermal modeling in compact layouts.
How does the 1.5SMC160AHM3/H differ from bidirectional TVS diodes like 1.5SMC160CA?
The 1.5SMC160AHM3/H is unidirectional and features a cathode band for polarity-sensitive placement, while 1.5SMC160CA is bidirectional with symmetrical clamping in both directions and no polarity marking. The unidirectional version offers lower leakage and tighter VBR tolerance, making it preferable for DC power rail protection.
