Product details
Overview
SMCJ16AH 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), 17.8–19.7V breakdown voltage (VBR), and 26.0V maximum clamping voltage (VC) at 60A peak pulse current. It protects automotive and industrial power rails against ISO 7637-2 Pulse 1/2a/2b/3a/3b transients and ESD.
For engineers reviewing the SMCJ16AH datasheet, SMCJ16AH pinout, SMCJ16AH application, or SMCJ16AH equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance values, clamping performance under 10/1000μs surge, and direct alternatives for automotive-grade overvoltage protection design.
Technical Context
The SMCJ16AH operates as a unidirectional avalanche diode, activated when reverse voltage exceeds its VBR range (17.8–19.7V at 1mA test current). Its glass-passivated junction ensures stable breakdown behavior and low leakage (<1μA at 16V), while fast response (<1.0ps) enables effective suppression of sub-nanosecond ESD events.
Thermally, it features RθJA = 55°C/W and RθJC = 10°C/W, supporting sustained operation up to TJ = +150°C. It meets JESD201 Class 2 whisker resistance and UL 94V-0 flammability requirements, confirming suitability for automated SMT assembly in harsh-environment applications.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16A | 600W rating, SMA package (smaller footprint), higher RθJA (85°C/W), lower IPPM (32.4A) | Lower power handling limits use to non-automotive, low-energy circuits | Select when board space is constrained and surge energy is ≤600W |
| SMCJ16A | Same 1500W rating and DO-214AB package, but non-AEC-Q101 qualified and no ISO 7637-2 validation | Lacks automotive qualification; suitable only for industrial/commercial designs without AEC compliance needs | Select when AEC-Q101 and ISO 7637-2 are not required, reducing cost |
Compared with SMAJ16A and SMCJ16A, the SMCJ16AH provides certified automotive robustness, tighter VBR tolerance (±5.4% vs ±6.3%), and guaranteed clamping at 26.0V-making it the preferred choice for safety-critical 12V rail protection where qualification and repeatable surge performance are mandatory.

FAQ
What is the clamping voltage of SMCJ16AH and how is it measured?
The SMCJ16AH has a maximum clamping voltage (VC) of 26.0 V, measured at 60 A peak pulse current (IPPM) under the standardized 10/1000 μs double-exponential surge waveform defined in Fig.5 of the datasheet. This value reflects worst-case voltage seen by protected circuitry during a high-energy transient, ensuring downstream components remain within safe operating limits. The SMCJ16AH consistently achieves this VC across its qualified temperature range (−55°C to +150°C).
Is SMCJ16AH unidirectional or bidirectional, and how is polarity identified?
The SMCJ16AH is a unidirectional TVS diode, designed for DC power line protection where polarity is fixed. Polarity is marked by a cathode band on the DO-214AB (SMC) package body-this band must be oriented toward the protected line (e.g., 12V rail), with the anode connected to ground. Bidirectional variants use "CH" or "CAH" suffixes (e.g., SMCJ16CH), which are electrically distinct and not interchangeable with SMCJ16AH.
Does SMCJ16AH meet automotive qualification standards?
Yes, the SMCJ16AH is AEC-Q101 qualified and explicitly validated for ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b transient immunity. Its construction-including glass-passivated junction, matte tin-plated leads, and JESD201 Class 2 whisker resistance-supports full automotive grade reliability. These qualifications are documented in Taiwan Semiconductor's official A2102 revision datasheet and apply specifically to the SMCJ16AH variant.
What is the maximum peak pulse current (IPPM) rating for SMCJ16AH?
The SMCJ16AH is rated for a maximum peak pulse current (IPPM) of 60 A under the standard 10/1000 μs surge waveform. This corresponds to its 1500 W peak pulse power rating at 25°C ambient, with derating applied above TA = 25°C per the pulse derating curve (Fig.2). At 60 A, the device clamps at ≤26.0 V, delivering predictable protection without thermal runaway.
How does SMCJ16AH differ from SMCJ16A in terms of qualification and performance?
The SMCJ16AH differs from SMCJ16A by its AEC-Q101 qualification, ISO 7637-2 validation, and tighter VBR tolerance (17.8–19.7 V vs. 17.8–21.8 V for SMCJ16H/A). While both share the same DO-214AB package and 1500W rating, only SMCJ16AH carries automotive certification and guaranteed clamping at 26.0 V. SMCJ16A lacks formal automotive qualification and should not be used in AEC-compliant designs.
