Product details
Overview
SMBJ16AHM3_A/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on power and signal lines. It features a 16 V stand-off voltage (VWM), 26.0 V maximum clamping voltage (VC) at 23.1 A peak pulse current (IPPM), and 600 W peak pulse power rating with 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial motor drives and telecom power supplies.
For engineers reviewing the SMBJ16AHM3_A/H datasheet, SMBJ16AHM3_A/H pinout, SMBJ16AHM3_A/H application, or SMBJ16AHM3_A/H equivalent, this page delivers verified electrical specs, thermal derating behavior, AEC-Q101 qualification status, halogen-free RoHS compliance, and real-world clamping performance under repetitive surge conditions.
Technical Context
This TVS diode operates as a unidirectional avalanche clamp, triggered when reverse voltage exceeds its 17.8–19.7 V breakdown range (VBR) at 1.0 mA test current. Its low incremental surge resistance ensures stable clamping during fast transients, while glass-passivated junction enables reliable operation up to 150 °C junction temperature.
The device meets J-STD-020 MSL Level 1 moisture sensitivity and withstands 100 A non-repetitive forward surge (IFSM, 8.3 ms half-sine), making it suitable for DC bus protection where high-energy switching events occur - such as IGBT gate driver supply rails or 24 V PLC input conditioning circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 16 V - Maximum continuous reverse operating voltage before significant leakage; defines safe operating margin below clamping threshold. |
| VBR (Breakdown Voltage) | 17.8–19.7 V at 1.0 mA - Confirmed avalanche initiation range; ensures predictable turn-on during overvoltage events. |
| VC (Clamping Voltage) | 26.0 V at 23.1 A (10/1000 µs) - Peak voltage seen by protected circuit during worst-case surge; critical for downstream IC voltage tolerance. |
| PPPM (Peak Pulse Power) | 600 W - Sustained energy absorption capability per transient; validated with 0.01% duty cycle repetition. |
| IPPM (Peak Pulse Current) | 23.1 A - Maximum surge current handled at rated clamping voltage; determines minimum trace width and fuse coordination. |
| TJmax | 150 °C - Maximum junction temperature; supports operation in enclosed industrial enclosures without active cooling. |
| Package | SMB (DO-214AA) - Standardized surface-mount outline with 5.59 mm max length; compatible with automated pick-and-place and reflow profiles up to 260 °C peak. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, unidirectional polarity marked by cathode band. Matte tin-plated leads meet J-STD-002 solderability and JESD22-B102 whisker resistance Class 2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side of protected line (e.g., GND or return path); conducts during forward surge events (e.g., IFSM). |
| Cathode | Reverse-biased clamping terminal | Connected to higher-potential side (e.g., +24 V rail); avalanches into conduction when VAK > VBR, shunting surge current to ground. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD; applicable in industrial control units requiring extended lifetime. |
| Halogen-free & RoHS-compliant (HM3 suffix) | Meets IEC 61249-2-21 and JEDEC J-STD-20E; eliminates brominated flame retardants without compromising UL 94 V-0 flammability rating. |
| 600 W peak pulse power (10/1000 µs) | Enables single-device protection against IEC 61000-4-5 Level 4 surges (4 kV line-to-ground) on 24 V systems with proper PCB layout. |
| Low clamping ratio (VC/VWM = 1.625) | Minimizes overvoltage stress on downstream components - e.g., keeps 3.3 V logic inputs within safe margin when protecting 5 V or 12 V bias rails. |
| MSL Level 1, 260 °C peak reflow | Eliminates bake requirements prior to assembly; supports standard lead-free reflow profiles without delamination risk. |
Applications
| Industrial Motor Drive Protection | Telecom DC Power Input |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16AHE3_A/H | Same electrical specs, but RoHS-compliant commercial grade (not halogen-free); no AEC-Q101 qualification. | Lacks automotive qualification and halogen-free certification; suitable only for non-automotive industrial use. | Select when AEC-Q101 and halogen-free requirements are not mandated, and cost optimization is prioritized. |
| SMBJ16CAHM3_A/H | Bidirectional variant with same VWM (16 V), but symmetrical clamping in both polarities; VC = 26.0 V at ±23.1 A. | Required for AC-coupled or floating signal lines (e.g., RS-485, CAN FD) where polarity reversal may occur. | Choose only when bidirectional protection is needed - unidirectional SMBJ16AHM3_A/H is optimal for DC rails with defined polarity. |
Compared with SMBJ16AHE3_A/H, SMBJ16AHM3_A/H adds halogen-free construction and AEC-Q101 validation without sacrificing clamping performance; versus SMBJ16CAHM3_A/H, it offers lower capacitance and tighter VBR tolerance for DC-specific protection, avoiding unnecessary bidirectional overhead.

FAQ
What is the clamping voltage of SMBJ16AHM3_A/H at its rated peak pulse current?
The SMBJ16AHM3_A/H has a maximum clamping voltage (VC) of 26.0 V when subjected to its rated peak pulse current of 23.1 A using the standardized 10/1000 µs waveform. This value is measured under specified test conditions per ANSI/IEEE C62.35 and ensures predictable overvoltage limiting for downstream components connected to the same rail as SMBJ16AHM3_A/H.
Is SMBJ16AHM3_A/H suitable for automotive applications?
Yes, SMBJ16AHM3_A/H is AEC-Q101 qualified and manufactured with halogen-free, RoHS-compliant materials - meeting stringent automotive reliability requirements for body electronics, power distribution units, and sensor interfaces. Its 150 °C maximum junction temperature and MSL Level 1 rating support under-hood and module-integrated deployment where SMBJ16AHM3_A/H operates continuously in thermally demanding environments.
How does the SMBJ16AHM3_A/H differ from the SMBJ16AHE3_A/H variant?
SMBJ16AHM3_A/H uses halogen-free molding compound and carries AEC-Q101 qualification, whereas SMBJ16AHE3_A/H is RoHS-compliant but not halogen-free and lacks automotive qualification. Both share identical electrical parameters (VWM, VBR, VC, PPPM), but SMBJ16AHM3_A/H is required for automotive Tier 1 suppliers and industrial applications mandating halogen-free compliance per IEC 61249-2-21.
What is the thermal resistance from junction to ambient for SMBJ16AHM3_A/H?
The typical thermal resistance from junction to ambient (RθJA) for SMBJ16AHM3_A/H is 100 °C/W when mounted on the minimum recommended pad layout (0.2" × 0.2" copper pads per terminal). This value guides thermal design for sustained power dissipation and derating above 25 °C ambient - for example, SMBJ16AHM3_A/H delivers full 5.0 W power dissipation only at TA ≤ 50 °C per datasheet limits.
Can SMBJ16AHM3_A/H be used in bidirectional signal protection?
No - SMBJ16AHM3_A/H is a unidirectional TVS diode, intended for DC power rail or polarized signal line protection. For bidirectional applications like RS-485, CAN, or AC-coupled interfaces, the bidirectional variant SMBJ16CAHM3_A/H must be selected instead. Using SMBJ16AHM3_A/H on a bidirectional line risks forward conduction during negative transients and inadequate clamping in reverse polarity.
