Product details
Overview
SMBJ160AHM3/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for robust overvoltage protection of DC power rails and signal lines. It features a 160 V stand-off voltage (VWM), 178–197 V breakdown voltage (VBR) at 1 mA, 259 V maximum clamping voltage (VC) at 2.3 A peak pulse current (IPPM), and 600 W peak pulse power rating with 10/1000 µs waveform - deployed in industrial motor drives, telecom power supplies, and automotive ECUs.
For engineers reviewing the SMBJ160AHM3/H datasheet, SMBJ160AHM3/H pinout, SMBJ160AHM3/H application, or SMBJ160AHM3/H equivalent, key selection criteria include clamping performance under 2.3 A surge, thermal resistance (RθJA = 100 °C/W), unidirectional polarity with cathode band marking, and halogen-free RoHS-compliant construction per JESD201 Class 2 whisker test.
Technical Context
This TVS diode operates as a shunt-clamping protector: during transient events exceeding VWM (160 V), it avalanches to limit voltage across protected circuitry to ≤259 V. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 µA at VWM).
Designed for automated SMT assembly, it meets MSL Level 1 per J-STD-020 (peak reflow 260 °C), supports 100 A non-repetitive forward surge (IFSM), and maintains operation from –55 °C to +150 °C junction temperature - enabling use in harsh-environment power conversion stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 160 V - maximum continuous reverse operating voltage before clamping initiates |
| VBR min/max | 178 V / 197 V at IT = 1 mA - guaranteed avalanche onset range for reliable turn-on margin |
| VC @ IPPM | 259 V at 2.3 A - clamped voltage seen by protected IC/MOSFET during standardized 10/1000 µs surge |
| PPPM | 600 W - peak transient energy absorption capability without failure under defined waveform |
| ID @ VWM | <1.0 µA - ultra-low reverse leakage preserves efficiency in high-impedance bias networks |
| TJ max | +150 °C - enables deployment in under-hood automotive or enclosed industrial enclosures |
| RθJA | 100 °C/W - thermal resistance dictates required PCB copper area (0.2" × 0.2") for safe 5.0 W steady-state dissipation |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, halogen-free, matte tin-plated leads. Cathode identified by molded band on case end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection point | Connected to ground or low-voltage reference; completes clamping path during overvoltage |
| Cathode | High-side connection point | Connected to protected line (e.g., 160 V rail); band-marked end defines polarity for unidirectional operation |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 µs) | Enables single-device protection against IEC 61000-4-5 Level 4 surges (4 kV/2 Ω) on 160 V systems |
| Clamping ratio VC/VBR ≈ 1.46 | Indicates tight voltage control - lower overshoot than typical silicon diodes, reducing stress on downstream MOSFETs |
| MSL Level 1, 260 °C peak reflow | Supports standard lead-free SMT processes without preconditioning or special handling |
| AEC-Q101 qualified variant available | HM3 suffix confirms qualification for automotive powertrain and body electronics applications |
| Glass passivated junction | Ensures long-term stability of VBR and low parametric drift across temperature and life cycles |
Applications
| Industrial Motor Drives | Telecom Power Supplies |

IC Role / Device Role / Timing Role: Low-leakage (≤1 µA) unidirectional TVS placed between signal line and local ground plane. Use Value: Preserves measurement accuracy by minimizing DC error contribution while delivering fast response (<1 ns) to ESD and EFT events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160A-M3/52 | Same electrical specs, but commercial-grade (non-AEC-Q101), standard RoHS (not halogen-free) | Lacks automotive qualification and whisker-test compliance; suitable for industrial/commercial only | Select when AEC-Q101 and halogen-free requirements are not mandated |
| SMBJ160AHM3_B/I | Identical device, differing only in packaging: 3200-piece 13" tape-and-reel vs. 750-piece 7" reel (H suffix) | No functional or electrical difference; choice driven by production volume and SMT feeder compatibility | Select for high-volume automated assembly requiring larger reels and optimized changeover frequency |
Compared with SMBJ160AHM3/H, the M3/52 variant omits automotive qualification and halogen-free materials, while the HM3_B/I offers identical performance in higher-volume packaging - enabling cost-optimized sourcing without compromising clamping behavior or thermal derating.

FAQ
What is the clamping voltage of SMBJ160AHM3/H at its rated peak pulse current?
The SMBJ160AHM3/H has a maximum clamping voltage (VC) of 259 V at 2.3 A peak pulse current (IPPM) under the 10/1000 µs waveform. This value defines the upper voltage limit imposed on protected circuitry during surge events and is measured with the device mounted on 0.2" × 0.2" copper pads per JEDEC standards.
Is SMBJ160AHM3/H suitable for automotive applications?
Yes - the HM3 suffix indicates SMBJ160AHM3/H is halogen-free, RoHS-compliant, and AEC-Q101 qualified. It meets automotive reliability requirements for powertrain and body electronics, including temperature cycling, humidity testing, and mechanical shock per AEC-Q101 Rev D.
How does the SMBJ160AHM3/H differ from the SMBJ160A-E3 variant?
The SMBJ160AHM3/H uses halogen-free molding compound and passes JESD201 Class 2 whisker testing, whereas SMBJ160A-E3 is RoHS-compliant but not halogen-free and lacks AEC-Q101 qualification. Both share identical electrical parameters and SMB package dimensions.
What is the reverse leakage current specification for SMBJ160AHM3/H at 160 V?
At VWM = 160 V and TA = 25 °C, SMBJ160AHM3/H exhibits a maximum reverse leakage current (ID) of 1.0 µA. This low leakage ensures minimal power loss in standby mode and avoids loading sensitive high-impedance sensor interfaces.
Can SMBJ160AHM3/H be used in bidirectional configurations?
No - SMBJ160AHM3/H is a unidirectional TVS diode, identifiable by its cathode band marking. For bidirectional protection at the same voltage level, the SMBJ160CA variant must be selected, which provides symmetrical clamping in both polarities.
