Product details
Overview
SMCJ16H from Taiwan Semiconductor is a unidirectional 1500W surface-mount transient voltage suppressor (TVS) diode in DO-214AB (SMC) package, with 16V working stand-off voltage (VWM), 17.8–21.8V breakdown voltage (VBR), and 28.8V maximum clamping voltage (VC) at 54A peak pulse current - designed for automotive-grade ESD and surge protection in power supply rails and I/O lines.
For engineers reviewing the SMCJ16H datasheet, SMCJ16H pinout, SMCJ16H application, or SMCJ16H equivalent, this device delivers AEC-Q101 qualification, ISO 7637-2 Pulse 1/2a/2b/3a/3b compliance, sub-1ps response time, <1μA reverse leakage above 10V, and robust thermal performance (RθJC = 10°C/W) for high-reliability industrial and automotive systems.
Technical Context
The SMCJ16H operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its VBR range (17.8–21.8V @ 1mA), clamping transients to ≤28.8V at 54A (10/1000μs waveform). Its glass-passivated junction ensures stable breakdown and low leakage (<1μA @ 16V).
Designed for automotive environments, it meets AEC-Q101 stress testing and ISO 7637-2 immunity requirements for load dump and inductive switching events, with junction temperature rated from –55°C to +150°C and moisture sensitivity level 1 per J-STD-020.
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 / 21.8 V @ 1 mA - Confirmed avalanche initiation range under standardized test conditions |
| VC @ IPPM | 28.8 V @ 54 A - Clamped voltage during 10/1000μs surge, defining worst-case downstream voltage stress |
| PPK | 1500 W - Peak pulse power handling capability, enabling protection against high-energy transients |
| IR @ VWM | <1 μA - Negligible leakage current at operating voltage, minimizing standby power loss |
| TJ max | +150 °C - Maximum junction temperature supporting under-hood and industrial ambient operation |
| RθJC | 10 °C/W - Low thermal resistance from junction to case, critical for sustained surge duty cycles |
Pinout & Package
Package: DO-214AB (SMC), surface-mount, single-die unidirectional configuration with cathode band marking. Matte tin-plated leads, UL 94V-0 molding compound, 0.210g weight.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16A | 600W PPK rating, SMB package (smaller footprint), higher RθJA (85°C/W), same VWM/VBR/VC specs | Limited to lower-energy transients; unsuitable for ISO 7637-2 Pulse 1 or sustained surge duty | Select when board space is constrained and surge energy remains below 600W |
| 1.5KE16A | Through-hole DO-201 package, 1500W rating, but slower response (>1ns), no AEC-Q101 or ISO 7637-2 validation | Not qualified for automotive use; requires PCB mounting changes and lacks automotive environmental certification | Choose only for cost-sensitive non-automotive industrial designs where leaded assembly is acceptable |
Compared with SMBJ16A and 1.5KE16A, the SMCJ16H provides superior thermal management (RθJC = 10°C/W), automotive qualification, and verified ISO 7637-2 immunity - making it the preferred choice for under-hood and safety-critical 12V systems requiring repeatable 1500W surge resilience.

FAQ
What is the breakdown voltage range for SMCJ16H?
The SMCJ16H has a minimum breakdown voltage (VBR) of 17.8 V and a maximum of 21.8 V, measured at 1 mA test current per ANSI/IEEE C62.35. This range ensures reliable avalanche initiation while accommodating process variation, and is confirmed in the official Taiwan Semiconductor datasheet revision A2102.
Is SMCJ16H unidirectional or bidirectional?
The SMCJ16H is a unidirectional TVS diode, indicated by the absence of "C" or "CA" suffix. It conducts only in reverse bias (cathode positive relative to anode) and must be oriented accordingly in circuit layout. Bidirectional variants require "CH" or "CAH" suffixes (e.g., SMCJ16CH).
Does SMCJ16H meet AEC-Q101 and ISO 7637-2 standards?
Yes, SMCJ16H is explicitly AEC-Q101 qualified and certified to meet ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b test waveforms per the Taiwan Semiconductor datasheet (Version A2102). These qualifications are validated through full stress testing, not inferred from family-level claims.
What is the maximum clamping voltage of SMCJ16H and at what current?
The SMCJ16H has a maximum clamping voltage (VC) of 28.8 V at 54 A peak pulse current (IPPM), using the standard 10/1000 μs double-exponential waveform. This value defines the upper voltage limit imposed on protected circuitry during worst-case surge events.
What package type does SMCJ16H use and what are its key mechanical features?
SMCJ16H uses the DO-214AB (SMC) surface-mount package: matte tin-plated leads compliant with J-STD-002, UL 94V-0 molding compound, polarity marked by cathode band, and moisture sensitivity level 1 per J-STD-020 - enabling robust automated placement and reflow compatibility.
