Product details
Overview
SMBJ16CAHM3_A/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on signal and power lines. It features a 16 V standoff 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 and telecom equipment.
For engineers reviewing the SMBJ16CAHM3_A/H datasheet, SMBJ16CAHM3_A/H pinout, SMBJ16CAHM3_A/H application, or SMBJ16CAHM3_A/H equivalent, this device is selected for robust ESD and surge protection where bidirectional clamping, low leakage (<1.0 µA at VWM), and AEC-Q101-qualified halogen-free construction are required.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with breakdown voltage (VBR) specified between 17.8 V (min) and 19.7 V at 1.0 mA test current. Its clamping behavior is characterized by low dynamic impedance and fast response time (<1 ns), enabling effective suppression of lightning-induced surges and inductive switching transients.
The device uses a glass-passivated silicon junction and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak temperature. Its thermal resistance (RθJA) is 100 °C/W, and maximum junction temperature is rated at +150 °C - supporting reliable operation in high-temperature industrial environments without forced cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 16 V - maximum continuous reverse operating voltage before clamping begins |
| VBR (min/max) | 17.8 V / 19.7 V at 1.0 mA - ensures reliable triggering above normal line voltage with margin |
| VC @ IPPM | 26.0 V at 23.1 A - limits transient voltage seen by downstream circuitry during 10/1000 µs surge |
| IPPM | 23.1 A - peak surge current capability under standardized 10/1000 µs waveform |
| PPPM | 600 W - peak pulse power handling capacity for short-duration transients |
| ID @ VWM | <1.0 µA - ultra-low leakage preserves signal integrity and minimizes standby power loss |
| TJ max. | +150 °C - enables use in under-hood automotive and high-ambient industrial applications |
Pinout & Package

Applications
| Industrial Motor Drives | Automotive Sensor Interfaces |
|---|---|
Use Scenario: Protection of gate drivers and feedback lines against inductive kickback from BLDC motor windings. IC Role / Device Role / Timing Role: Bidirectional clamping element placed across MOSFET gate-source or op-amp input pins.

Use Scenario: ESD and load-dump protection on LIN/CAN sensor nodes in engine bay modules. IC Role / Device Role / Timing Role: Primary TVS at connector interface, shunting transients before reaching MCU I/O or transceiver inputs. Use Value: Withstands ISO 7637-2 Pulse 1 (−150 V/50 Ω) and IEC 61000-4-2 ±30 kV contact discharge due to low VC and fast response. |
| Telecom Power Feeds | Consumer USB-C Port Protection |
Use Scenario: Surge protection on 48 V DC power input of PoE-powered network switches. IC Role / Device Role / Timing Role: Secondary-level TVS after primary MOV, absorbing residual energy not diverted upstream.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16CAHE3_A/H | Same electrical specs; RoHS-compliant but not halogen-free; lacks AEC-Q101 qualification | Suitable for commercial-grade industrial boards where automotive qualification is not required | Select when cost sensitivity outweighs halogen-free or automotive reliability needs |
| SMAJ16CAHM3_A/H | Lower PPPM (400 W vs. 600 W); same VWM, VC, and package footprint; SMA (DO-214AC) package | Acceptable for lower-energy transients; requires PCB pad revision due to smaller body (4.3 × 2.6 mm) | Choose only if system-level surge testing confirms 400 W is sufficient and layout allows SMA footprint |
Compared with SMBJ16CAHE3_A/H and SMAJ16CAHM3_A/H, the SMBJ16CAHM3_A/H uniquely combines 600 W surge rating, halogen-free construction, and AEC-Q101 qualification in the SMB package - making it the preferred choice for automotive-qualified designs requiring highest pulse power margin without footprint change.

FAQ
What is the clamping voltage of SMBJ16CAHM3_A/H at its rated peak pulse current?
The SMBJ16CAHM3_A/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 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and guarantees that protected circuitry will not experience voltages exceeding 26.0 V during standardized surge events - critical for safeguarding 3.3 V or 5 V logic interfaces.
Is SMBJ16CAHM3_A/H suitable for automotive applications?
Yes, SMBJ16CAHM3_A/H is AEC-Q101 qualified and manufactured with halogen-free, RoHS-compliant materials - meeting automotive reliability requirements for under-hood and body-control module applications. Its 150 °C maximum junction temperature and MSL Level 1 rating further validate suitability for automotive SMT assembly and operational environments.
How does the bidirectional configuration of SMBJ16CAHM3_A/H affect PCB layout?
The SMBJ16CAHM3_A/H has no polarity marking and identical electrical behavior in both directions, eliminating orientation constraints during placement. Unlike unidirectional TVS diodes, it can be mounted without regard to anode/cathode alignment - simplifying automated assembly and reducing risk of misplacement in differential or AC-coupled signal paths.
What is the standoff voltage (VWM) of SMBJ16CAHM3_A/H, and why is it important?
The standoff voltage (VWM) of SMBJ16CAHM3_A/H is 16 V - the maximum continuous reverse voltage the device tolerates without entering avalanche conduction. This parameter ensures the TVS remains non-conductive during normal operation, avoiding power loss or signal distortion while providing headroom for transient clamping above system operating voltage.
Does SMBJ16CAHM3_A/H require derating at elevated ambient temperatures?
Yes, SMBJ16CAHM3_A/H must be derated above 25 °C ambient per Figure 2 in the Vishay datasheet (Document Number: 88392). At 85 °C ambient, its peak pulse power drops to ~420 W (70 % of 600 W), and at 125 °C, it falls to ~240 W (40 %). Designers must apply thermal derating curves when deploying in high-temperature enclosures or near heat sources.
