Product details
Overview
SMCJ160AHM3_A/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed for high-energy surge protection with 160 V standoff voltage, 259 V clamping voltage at 5.8 A peak pulse current, and 1500 W peak pulse power rating. It protects MOSFETs, ICs, and sensor signal lines against inductive switching transients and lightning-induced surges in automotive and industrial power electronics.
For engineers reviewing the SMCJ160AHM3_A/H datasheet, SMCJ160AHM3_A/H pinout, SMCJ160AHM3_A/H application, or SMCJ160AHM3_A/H equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification status, halogen-free RoHS compliance, thermal resistance (RθJA = 75 °C/W), and junction temperature range (–55 to +150 °C).
Technical Context
This TVS diode operates as a clamping device that remains non-conductive below its reverse standoff voltage (VWM = 160 V) and rapidly transitions to low-impedance conduction above its breakdown voltage (VBR = 178–197 V at IT = 1 mA). Its glass-passivated junction ensures stable avalanche characteristics and fast response time (<1 ns) to transient events.
Designed for surface-mount assembly on standard PCB copper pads (8.0 mm × 8.0 mm per terminal), it meets J-STD-020 MSL Level 1 and JESD 201 Class 2 whisker resistance requirements. The matte tin-plated leads are solderable per J-STD-002 and JESD 22-B102 standards.
Key Specifications

| VBR min/max | 178 V / 197 V at 1 mA - Breakdown voltage range ensuring reliable avalanche initiation across process variation and temperature. |
| VC @ IPPM | 259 V at 5.8 A - Clamping voltage under 10/1000 µs surge; determines maximum voltage stress imposed on downstream components. |
| PPPM | 1500 W - Peak pulse power handling capability; enables robust protection against high-energy transients like ISO 7637-2 Pulse 5a. |
| RθJA | 75 °C/W - Junction-to-ambient thermal resistance; informs minimum required PCB copper area for thermal management at 6.5 W steady-state dissipation. |
| TJ range | –55 °C to +150 °C - Operating and storage temperature envelope; supports under-hood automotive and industrial environments. |
| Package | SMC (DO-214AB) - Standardized surface-mount outline with 2.06 mm height and 7.75 mm body length; compatible with automated pick-and-place. |
Pinout & Package
SMCJ160AHM3_A/H uses the SMC (DO-214AB) package: a rectangular surface-mount case with two coplanar terminals, cathode identified by a band on the body. Mounting requires 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal for rated power derating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry (unidirectional) | Connected to system ground or lower-potential rail; forms low-impedance path during reverse surge. |
| Cathode | Reverse voltage reference (marked end) | Connected to protected line; blocks 160 V DC but conducts when transient exceeds 178 V breakdown threshold. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing-enables use in engine control units and ADAS sensors. |
| Halogen-free & RoHS-compliant | Meets EU Directive 2011/65/EU and JEDEC JS709E; eliminates brominated flame retardants without compromising UL 94 V-0 flammability rating. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., <100 ns edges), improving protection margin for sensitive CMOS inputs. |
| Very fast response time | Sub-nanosecond turn-on ensures clamping occurs before transient energy damages downstream silicon-critical for protecting 3.3 V/5 V logic interfaces. |
| Glass passivated junction | Provides stable, repeatable avalanche characteristics over lifetime and temperature; prevents parameter drift due to moisture or contamination ingress. |
Applications
| Automotive Power Distribution | Industrial Motor Drive Inputs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160AHE3_A/H | Lower PPPM (600 W), same VWM/VC, SMB (DO-214AA) package (smaller footprint, higher RθJA = 110 °C/W) | Not suitable for 1500 W surge events; limited to lower-energy transients like ESD or capacitive coupling. | Select only when board space is constrained and surge threat level is classified as IEC 61000-4-2/4-4, not ISO 7637-2. |
| SMCJ160AHE3_A/H | Same electrical specs and package, but RoHS-compliant commercial grade (non-halogen-free, no AEC-Q101 qualification) | Lacks automotive qualification and halogen-free certification; unsuitable for Tier-1 automotive BOMs requiring PPAP documentation. | Use for cost-sensitive industrial or consumer designs where AEC-Q101 and halogen-free compliance are not mandated. |
Compared with SMCJ160AHM3_A/H, SMBJ160AHE3_A/H trades surge capacity for compactness, while SMCJ160AHE3_A/H retains full electrical performance but omits halogen-free materials and automotive qualification-making SMCJ160AHM3_A/H the sole choice for AEC-Q101-compliant, environmentally regulated high-energy protection.

FAQ
What is the clamping voltage of SMCJ160AHM3_A/H under a 10/1000 µs surge?
The SMCJ160AHM3_A/H has a maximum clamping voltage (VC) of 259 V when subjected to its rated peak pulse current (IPPM = 5.8 A) using a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during surge events. The SMCJ160AHM3_A/H achieves this clamping performance while maintaining low incremental surge resistance for minimal overshoot.
Is SMCJ160AHM3_A/H qualified for automotive applications?
Yes, SMCJ160AHM3_A/H is AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "HM3" and documentation in the SMCJ5.0A–SMCJ188CA datasheet (Document Number 88394, Revision 09-Jan-2024). This qualification covers stress tests including temperature cycling, high-temperature reverse bias, and ESD, making the SMCJ160AHM3_A/H suitable for under-hood and chassis-mounted automotive electronics such as body control modules and ADAS sensor interfaces.
What does the "HM3" suffix in SMCJ160AHM3_A/H indicate?
The "HM3" suffix in SMCJ160AHM3_A/H denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. Per Vishay's ordering information table, "HM3" distinguishes this variant from "HE3" (RoHS-compliant AEC-Q101) and "M3" (halogen-free commercial grade). The "_A/H" further specifies packaging: 7-inch tape-and-reel with 850 units per reel. This coding ensures material compliance and automotive suitability are unambiguously defined for SMCJ160AHM3_A/H.
How does the thermal performance of SMCJ160AHM3_A/H affect PCB layout?
The SMCJ160AHM3_A/H has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal. To maintain safe junction temperature under 6.5 W continuous dissipation or during repetitive surges, designers must allocate sufficient copper area and consider internal layer thermal vias. Reducing pad size increases RθJA, risking thermal runaway-so PCB layout for SMCJ160AHM3_A/H must strictly follow Vishay's recommended land pattern.
Can SMCJ160AHM3_A/H be used in bidirectional protection circuits?
No, SMCJ160AHM3_A/H is a unidirectional TVS diode, as indicated by its "A" suffix (vs. "CA" for bidirectional variants like SMCJ160CA). Its cathode band marks polarity, and it conducts only during reverse surges above VBR; forward conduction follows standard diode behavior. For AC-coupled or symmetrical transient protection, a bidirectional part such as SMCJ160CA must be selected instead-SMCJ160AHM3_A/H is not functionally suitable for bidirectional applications.
