Product details
Overview
SMCJ16C-E3/57T from Vishay General Semiconductor is a bi-directional transient voltage suppressor (TVS) diode in DO-214AB (SMCJ) package, designed for clamping voltage transients on signal or power lines. It features a 16 V stand-off voltage (VWM), 26.0 V maximum clamping voltage at 57.7 A peak pulse current, 1500 W peak pulse power rating, and AEC-Q101 qualification for automotive reliability.
For engineers reviewing the SMCJ16C-E3/57T datasheet, SMCJ16C-E3/57T pinout, SMCJ16C-E3/57T application, or SMCJ16C-E3/57T equivalent, key selection criteria include bi-directional clamping capability, 1500 W surge handling under 10/1000 µs waveform, DO-214AB thermal performance (RθJA = 75 °C/W), and compliance with UL 497B and AEC-Q101 for harsh-environment deployment.
Technical Context
The SMCJ16C-E3/57T operates as a bi-directional avalanche diode, symmetrically clamping both positive and negative transients without polarity dependence. Its glass-passivated junction enables fast response time (<1 ps) and low incremental surge resistance, critical for protecting downstream ICs during ESD or load-switching events.
Designed for surface-mount assembly on 8.0 mm × 8.0 mm copper pads, it delivers 1500 W peak pulse power dissipation per 10/1000 µs waveform while maintaining TJ ≤ 150 °C. The device meets MSL Level 1 per J-STD-020 and supports reflow up to 260 °C peak temperature.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16CA-E3/61T | Lower PPPM (400 W), smaller DO-214AC (SMA) package, higher RθJA (110 °C/W) | Suitable only for lower-energy transients; limited to consumer-grade ambient conditions | Select when board space is constrained and surge threat level is ≤400 W (e.g., USB ports, low-voltage logic) |
| SMCJ16CAHE3/57T | Identical electrical specs but AEC-Q101 qualified version with HE3 suffix; same DO-214AB package | Required for automotive OEM designs requiring full qualification documentation and traceability | Choose when automotive PPAP submission or long-term reliability validation is mandated |
Compared with SMCJ16C-E3/57T, SMAJ16CA-E3/61T offers footprint savings at the cost of 73 % lower surge capacity and reduced thermal margin, while SMCJ16CAHE3/57T provides identical protection performance with certified automotive qualification - making it the drop-in replacement where AEC-Q101 compliance is contractually required.

FAQ
What does the "C" suffix indicate in SMCJ16C-E3/57T?
The "C" in SMCJ16C-E3/57T denotes bi-directional functionality - meaning the device clamps voltage transients of either polarity symmetrically. Unlike uni-directional variants (e.g., SMCJ16A), the SMCJ16C-E3/57T has no cathode marking and is used where AC signals, differential buses, or ungrounded lines require equal protection in both directions. This is confirmed in Vishay's datasheet section "DEVICES FOR BI-DIRECTION APPLICATIONS".
Is SMCJ16C-E3/57T RoHS compliant and halogen-free?
Yes, SMCJ16C-E3/57T is RoHS compliant per Directive 2011/65/EU, as indicated by the "E3" suffix and documented in Vishay's Material Categorization Policy (doc?99912). It also meets JEDEC JS709A halogen-free requirements. The molding compound is UL 94 V-0 rated, and terminals are matte tin-plated per J-STD-002 - all verified in the official datasheet revision 11-Dec-12.
What is the maximum clamping voltage for SMCJ16C-E3/57T and under what test condition?
The maximum clamping voltage (VC) for SMCJ16C-E3/57T is 26.0 V, measured at 57.7 A peak pulse current (IPPM) using the standardized 10/1000 µs double-exponential waveform. This value is specified in the Electrical Characteristics table on page 2 of the Vishay datasheet (Document Number: 88394) and defines the upper voltage limit imposed on protected circuits during worst-case surge events.
Can SMCJ16C-E3/57T be used in place of a uni-directional TVS like SMCJ16A?
No - SMCJ16C-E3/57T is not a direct substitute for SMCJ16A due to fundamental polarity differences. SMCJ16A is uni-directional with a defined cathode band and forward conduction path, while SMCJ16C-E3/57T is bi-directional with no polarity marking. Replacing one with the other risks incorrect biasing, failed clamping, or short-circuit behavior in DC-biased applications such as power rail protection.
What is the thermal resistance and recommended pad layout for SMCJ16C-E3/57T?
SMCJ16C-E3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal, as specified in the Thermal Characteristics table. This pad size is mandatory to achieve rated 1500 W pulse power; smaller pads increase thermal impedance and risk junction overheating during repeated surges.
