Product details
Overview
SMBJ16AHM3/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 (10/1000 µs waveform), making it suitable for protecting MOSFETs and ICs in industrial power supplies.
For engineers reviewing the SMBJ16AHM3/H datasheet, SMBJ16AHM3/H pinout, SMBJ16AHM3/H application, or SMBJ16AHM3/H equivalent, key selection criteria include its 1.0 µA max reverse leakage at VWM, AEC-Q101 qualification (HM3 suffix), halogen-free RoHS compliance, and thermal resistance of 100 °C/W (junction-to-ambient).
Technical Context
This TVS diode operates as a unidirectional clamping device with a cathode-band polarity marking, leveraging a glass-passivated silicon junction for stable breakdown behavior. Its 17.8–19.7 V breakdown voltage range (VBR) at 1.0 mA test current ensures reliable triggering above the 16 V stand-off level while maintaining low incremental surge resistance.
The device delivers fast transient response (<1 ps typical) and meets MSL Level 1 per J-STD-020 with 260 °C lead-free reflow compatibility. Its 150 °C maximum junction temperature and 100 A IFSM (8.3 ms half-sine) support robust surge handling in automotive and industrial environments where repetitive switching-induced spikes occur.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 16 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC/AC working limit. |
| VC @ IPPM | 26.0 V - Clamped voltage during 23.1 A 10/1000 µs surge; determines protected circuit's maximum transient exposure. |
| IPPM | 23.1 A - Peak surge current capability under standard 10/1000 µs waveform; sets single-event energy absorption limit. |
| PPPM | 600 W - Peak pulse power rating; defines transient energy handling capacity without failure. |
| VBR min/max | 17.8 V / 19.7 V - Breakdown voltage range at 1.0 mA; ensures consistent turn-on margin above VWM. |
| ID @ VWM | 1.0 µA - Reverse leakage current at stand-off voltage; critical for low-power sensor line protection. |
| TJ max | +150 °C - Maximum junction temperature; enables operation in high-ambient industrial or under-hood automotive locations. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, halogen-free, RoHS-compliant, matte tin-plated leads. Cathode identified by band marking; anode is unmarked end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient clamp output node | Connected to protected line; conducts surge current to ground when VWM exceeded. |
| Anode (unbanded end) | Reference/return path | Typically tied to system ground or low-impedance return; completes clamping current path. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 µs) | Enables protection against high-energy transients like ISO 7637-2 Pulse 1/2a/5a in automotive power nets. |

| MSL Level 1, 260 °C peak reflow | Supports standard lead-free SMT assembly without moisture sensitivity concerns or baking requirements. |
| Low 1.0 µA reverse leakage at VWM | Minimizes standby power loss and avoids false triggering in battery-powered or precision analog circuits. |
| Glass passivated chip junction | Ensures stable VBR over time and temperature, reducing parameter drift in long-life industrial applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16AHE3/H | Same electrical specs but RoHS-compliant commercial grade (E3); not AEC-Q101 qualified. | Lacks automotive qualification; suitable for industrial/commercial designs without automotive certification needs. | Select SMBJ16AHE3/H for cost-sensitive non-automotive applications where AEC-Q101 is not required. |
| SMBJ16CAHM3/H | Bidirectional variant; same VWM = 16 V but symmetrical clamping in both polarities. | Required for AC-coupled or dual-polarity signal lines (e.g., RS-485, USB D+/D−) where negative transients occur. | Choose SMBJ16CAHM3/H only when bidirectional protection is needed; unidirectional SMBJ16AHM3/H is optimal for DC rails. |
Compared with SMBJ16AHE3/H and SMBJ16CAHM3/H, the SMBJ16AHM3/H uniquely combines AEC-Q101 qualification, halogen-free construction, and unidirectional clamping-making it the preferred choice for automotive 12 V/24 V power rail protection where reliability and regulatory compliance are mandatory.

FAQ
What is the clamping voltage of SMBJ16AHM3/H at its rated peak pulse current?
The SMBJ16AHM3/H has a maximum clamping voltage (VC) of 26.0 V when subjected to its rated peak pulse current of 23.1 A under the standard 10/1000 µs waveform. This value is measured per JEDEC test conditions and defines the upper voltage limit imposed on protected circuitry during surge events. The SMBJ16AHM3/H maintains this clamping performance across its specified operating temperature range.
Is SMBJ16AHM3/H qualified for automotive applications?
Yes, SMBJ16AHM3/H is AEC-Q101 qualified, as indicated by the "HM3" suffix denoting halogen-free, RoHS-compliant, and automotive-grade construction. It undergoes stress testing including temperature cycling, highly accelerated life testing (HALT), and ESD per AEC-Q101 requirements. This makes SMBJ16AHM3/H suitable for use in automotive body control modules, infotainment power supplies, and other non-safety-critical vehicle subsystems.
How does the SMBJ16AHM3/H differ from the SMBJ16AHE3/H variant?
The SMBJ16AHM3/H and SMBJ16AHE3/H share identical electrical specifications-including VWM = 16 V, VC = 26.0 V, and PPPM = 600 W-but differ in qualification and material content. SMBJ16AHM3/H is halogen-free and AEC-Q101 qualified; SMBJ16AHE3/H is RoHS-compliant but commercial-grade only. Therefore, SMBJ16AHM3/H supports automotive deployment where SMBJ16AHE3/H does not.
What is the maximum reverse leakage current for SMBJ16AHM3/H at its stand-off voltage?
The SMBJ16AHM3/H exhibits a maximum reverse leakage current (ID) of 1.0 µA at its 16 V stand-off voltage (VWM) and 25 °C ambient temperature. This low leakage ensures minimal power loss in always-on circuits and avoids interference with high-impedance sensor inputs or battery-backed systems. The SMBJ16AHM3/H maintains tight leakage control across its full operating temperature range.
What package type and mounting method does SMBJ16AHM3/H use?
SMBJ16AHM3/H uses the SMB (DO-214AA) surface-mount package with matte tin-plated leads compatible with J-STD-002 and JESD 22-B102 soldering standards. It is supplied in 7" tape-and-reel format (code H) and requires standard SMT reflow profiles, including peak temperatures up to 260 °C (MSL Level 1). The cathode is marked by a visible band on the SMBJ16AHM3/H body.
