Product details
Overview
SMCJ16AHM3_A/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 16 V standoff voltage (VWM), 26.0 V clamping voltage (VC) at 57.7 A peak pulse current (IPPM), and 1500 W peak pulse power (PPPM). It protects MOSFETs, ICs, and sensor signal lines against inductive switching transients and ESD in automotive and industrial power rails.
For engineers reviewing the SMCJ16AHM3_A/H datasheet, SMCJ16AHM3_A/H pinout, SMCJ16AHM3_A/H application, or SMCJ16AHM3_A/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 in reverse-biased configuration, triggering when reverse voltage exceeds its breakdown range (17.8–19.7 V at 1 mA test current) to divert surge energy away from protected circuitry. Its glass-passivated junction ensures stable avalanche characteristics and low incremental surge resistance.
Designed for automated SMT assembly, it meets J-STD-020 MSL Level 1 (peak reflow 260 °C), JESD201 Class 2 whisker resistance, and UL 497B recognition (QVGQ2). The SMC package provides robust thermal dissipation with RθJL = 15 °C/W to leads under recommended 8.0 mm × 8.0 mm copper pad layout.
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 mA - guaranteed avalanche initiation window for reliable turn-on |
| VC @ IPPM | 26.0 V at 57.7 A - clamped voltage during 10/1000 µs surge, limiting stress on downstream components |
| PPPM | 1500 W - peak surge power handling capability per single transient event |
| ID @ VWM | 1.0 µA - ultra-low leakage ensuring minimal standby power loss in high-impedance circuits |
| TJ max | +150 °C - maximum junction temperature enabling operation in under-hood automotive environments |
| RθJA | 75 °C/W - thermal resistance defining required PCB copper area for thermal management |

Applications
| Automotive Power Rail Protection | Industrial Sensor Signal Line Protection |
|---|---|
Use Scenario: 12 V battery-supplied ECUs exposed to load dump (ISO 7637-2 Pulse 5a) and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power rail and chassis ground to clamp surges above 16 V.

FAQ
What is the breakdown voltage range of the SMCJ16AHM3_A/H?
The SMCJ16AHM3_A/H has a guaranteed breakdown voltage (VBR) range of 17.8 V to 19.7 V at 1 mA test current, measured per ANSI/IEEE C62.35. This range ensures consistent avalanche turn-on behavior across production lots and temperature extremes, critical for predictable clamping in automotive power rail protection circuits using the SMCJ16AHM3_A/H.
Is the SMCJ16AHM3_A/H suitable for automotive applications?
Yes, the SMCJ16AHM3_A/H is AEC-Q101 qualified and carries the HM3 suffix indicating halogen-free, RoHS-compliant construction. It is explicitly rated for automotive use per the Vishay datasheet revision 09-Jan-2024 (Document Number: 88394), making it appropriate for engine control units, body electronics, and ADAS modules where the SMCJ16AHM3_A/H must survive temperature cycling, vibration, and load dump events.
What is the maximum clamping voltage of the SMCJ16AHM3_A/H at its rated peak pulse current?
The SMCJ16AHM3_A/H clamps to a maximum of 26.0 V at its rated peak pulse current of 57.7 A (10/1000 µs waveform). This VC value defines the upper voltage limit imposed on protected circuitry during surge events, directly determining whether downstream components like 3.3 V logic or CAN transceivers remain within safe operating limits when the SMCJ16AHM3_A/H activates.
Does the SMCJ16AHM3_A/H have polarity marking, and how is it identified?
Yes, the SMCJ16AHM3_A/H is unidirectional and features a cathode band marked on the SMC (DO-214AB) package body. Per Vishay documentation, the band denotes the cathode terminal, which must be connected to the line being protected, while the anode connects to ground or reference potential-correct orientation is essential for proper operation of the SMCJ16AHM3_A/H in reverse-biased clamping mode.
What is the thermal resistance junction-to-ambient for the SMCJ16AHM3_A/H under standard mounting conditions?
The SMCJ16AHM3_A/H has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on the minimum recommended 8.0 mm × 8.0 mm copper pads per terminal. This value is critical for calculating allowable power dissipation and verifying safe junction temperature rise in high-temperature environments where the SMCJ16AHM3_A/H operates continuously near its 6.5 W steady-state rating.
