Product details
Overview
SMCJ160AHM3/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 under 10/1000 μs waveform. It protects MOSFETs, ICs, and sensor signal lines in automotive power systems and industrial motor drives.
For engineers reviewing the SMCJ160AHM3/H datasheet, SMCJ160AHM3/H pinout, SMCJ160AHM3/H application, or SMCJ160AHM3/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 transitions from high-impedance standby to low-impedance conduction when reverse voltage exceeds its breakdown threshold (VBR = 178–197 V). Its glass-passivated junction ensures stable avalanche behavior and fast response time (<1 ns) to transients induced by inductive switching or ESD events.
Designed for PCB-level protection, it delivers 1500 W peak pulse power handling on standard 8.0 mm × 8.0 mm copper pads, with low incremental surge resistance and clamping voltage tightly controlled at 259 V under rated IPPM - critical for safeguarding 150 V-rated power stages without overvoltage stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 160 V - Maximum continuous reverse operating voltage before leakage exceeds 1.0 μA; sets upper limit for system bus voltage compatibility. |
| VBR min/max | 178 V / 197 V - Breakdown occurs within this range at 1 mA test current; defines reliable turn-on margin above VWM. |
| VC @ IPPM | 259 V - Clamped voltage during 5.8 A 10/1000 μs surge; determines maximum stress imposed on protected downstream components. |
| PPPM | 1500 W - Peak pulse power dissipation capability; enables robust protection against IEC 61000-4-5 Level 4 surges. |
| RθJA | 75 °C/W - Junction-to-ambient thermal resistance on standard pad layout; informs derating requirements above 25 °C ambient. |
| TJ max | +150 °C - Maximum allowable junction temperature; supports operation in under-hood automotive environments. |
| Package | SMC (DO-214AB) - Industry-standard surface-mount outline with 2.06 mm height and 7.75 mm body length; compatible with automated pick-and-place. |
Pinout & Package
SMCJ160AHM3/H uses the SMC (DO-214AB) package: molded epoxy case with matte tin-plated leads, MSL Level 1 moisture sensitivity, and cathode band marking on the unidirectional variant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / Surge return path | Connected to ground or low-side reference; completes clamping loop during transient events. |
| Cathode | Reverse-biased terminal / Protection node | Connected to protected line (e.g., 160 V rail); conducts avalanche current when VAK > VBR. |
Key Features
| Feature | Design Value |
|---|---|

| Halogen-free & RoHS-compliant | Meets EU Directive 2011/65/EU and JEDEC J-STD-20D; eliminates brominated flame retardants in molding compound. |
| Glass passivated junction | Ensures consistent avalanche characteristics over lifetime and prevents parameter drift due to environmental contamination. |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients, improving protection margin for sensitive gate drivers and controllers. |
| MSL Level 1 rating | Allows unlimited floor life and reflow soldering at peak temperature up to 260 °C without preconditioning. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ160AHE3/A | Lower PPPM (400 W), SMA package (smaller footprint, higher RθJA = 110 °C/W), same VWM/VC specs. | Suitable for space-constrained consumer electronics but not automotive-grade surge levels. | Select when board area is critical and surge threat level is limited to IEC 61000-4-2 ESD only. |
| SMCJ160A-M3/57T | Same electrical specs and SMC package, but commercial-grade (non-AEC-Q101) and non-halogen-free variant. | Acceptable for industrial automation where automotive qualification is not mandated. | Choose for cost-sensitive BOMs where AEC-Q101 and halogen-free compliance are not required. |
Compared with SMCJ160AHM3/H, SMAJ160AHE3/A offers reduced surge capacity in a smaller package, while SMCJ160A-M3/57T provides identical protection performance without automotive qualification - enabling trade-offs between reliability assurance, footprint, and cost.

FAQ
What is the clamping voltage of the SMCJ160AHM3/H under maximum rated surge current?
The SMCJ160AHM3/H has a maximum clamping voltage (VC) of 259 V when subjected to its rated peak pulse current (IPPM) of 5.8 A using a 10/1000 μs waveform. This value is measured at the device terminals under standardized test conditions and defines the upper voltage limit imposed on protected circuitry during surge events. The SMCJ160AHM3/H maintains this clamping performance across its full operating temperature range.
Is the SMCJ160AHM3/H qualified for automotive applications?
Yes, the SMCJ160AHM3/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 high-temperature operating life, temperature cycling, and ESD robustness - making the SMCJ160AHM3/H suitable for under-hood and chassis-mounted automotive electronics.
What does the "HM3" suffix indicate in SMCJ160AHM3/H?
The "HM3" suffix in SMCJ160AHM3/H denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. Per Vishay's ordering nomenclature, "H" indicates AEC-Q101 qualification, "M3" specifies halogen-free and RoHS-compliant materials, and the trailing "/H" refers to 7-inch tape-and-reel packaging (850 units per reel). This distinguishes SMCJ160AHM3/H from commercial variants like SMCJ160A-M3/57T.
Can the SMCJ160AHM3/H be used in bidirectional configurations?
No, the SMCJ160AHM3/H is a unidirectional TVS diode, as indicated by its "A" suffix and cathode band marking. Bidirectional versions use the "CA" suffix (e.g., SMCJ160CA) and lack polarity markings. Using SMCJ160AHM3/H in reverse-biased AC applications would result in forward conduction and failure; for bidirectional protection, select the corresponding CA variant with matched VWM and VC ratings.
What is the thermal resistance of the SMCJ160AHM3/H, and how does it affect layout design?
The SMCJ160AHM3/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 terminal, as specified in the Vishay datasheet. This value requires adequate copper area and thermal vias for high-duty-cycle surge scenarios; reducing pad size increases RθJA, lowering safe power dissipation. Layout must follow the recommended mounting pad dimensions in the SMC (DO-214AB) outline drawing to maintain thermal performance and reliability of the SMCJ160AHM3/H.
