Product details
Overview
SMCJ16A-E3/57T from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed for clamping voltage transients on power and signal lines. It features 16 V standoff voltage (VWM), 26.0 V maximum clamping voltage (VC) at 57.7 A peak pulse current (IPPM), and 1500 W peak pulse power (10/1000 μs waveform), commonly deployed to protect MOSFETs and ICs in industrial power supplies.
For engineers reviewing the SMCJ16A-E3/57T datasheet, SMCJ16A-E3/57T pinout, SMCJ16A-E3/57T application, or SMCJ16A-E3/57T equivalent, key selection criteria include verified unidirectional clamping performance, JEDEC-compliant SMC package thermal behavior, AEC-Q101 qualification eligibility (via HE3 suffix variants), and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads.
Technical Context
This TVS diode operates as a voltage-clamping protection device that enters avalanche breakdown when reverse voltage exceeds its 17.8–19.7 V breakdown range (VBR at 1.0 mA test current). Its low incremental surge resistance and fast response time ensure effective suppression of ESD and inductive switching transients before downstream components are damaged.
The device is rated for 150 °C maximum junction temperature and exhibits a +0.089 %/°C temperature coefficient of VBR, enabling predictable clamping behavior across automotive and industrial ambient ranges. Polarity is marked by a cathode band; it is not bidirectional - no CA suffix - and requires correct orientation during PCB layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 16 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC/AC bias margin. |
| VC @ IPPM | 26.0 V - Clamped voltage at 57.7 A peak pulse current (10/1000 μs); determines maximum stress on protected IC/MOSFET. |
| IPPM (Peak Pulse Current) | 57.7 A - Maximum transient current the device safely shunts without degradation; validated per Fig. 3 waveform. |
| PPPM (Peak Pulse Power) | 1500 W - Transient energy-handling capability under standardized 10/1000 μs surge; enables robust lightning/inductive spike immunity. |
| TJmax | 150 °C - Maximum allowable junction temperature; supports operation in under-hood automotive or enclosed industrial enclosures. |
| RθJA | 75 °C/W - Junction-to-ambient thermal resistance on standard 0.31″ × 0.31″ copper pads; informs derating above 25 °C ambient. |
| Package | SMC (DO-214AB) - Surface-mount outline with matte tin-plated leads, MSL Level 1, compatible with reflow profiles up to 260 °C peak. |
Pinout & Package
SMCJ16A-E3/57T uses the industry-standard SMC (DO-214AB) package: a low-profile, rectangular surface-mount case with two terminals. Cathode is identified by a visible band on the body; anode is the unmarked end. Leads are matte tin-plated and solderable per J-STD-002 and JESD 22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Reverse-biased terminal | Connected to protected line (e.g., VIN or signal rail); conducts avalanche current during overvoltage events. |
| Anode (unmarked end) | Reference/ground return | Typically tied to system ground or low-impedance return path; completes clamping loop during transient conduction. |
Key Features
| Feature | Design Value |
|---|---|
| 1500 W peak pulse power rating | Enables reliable suppression of high-energy transients (e.g., ISO 7637-2 Pulse 1/2a/5a) without failure in 12 V/24 V systems. |
| 26.0 V clamping voltage at 57.7 A | Keeps protected MOSFET gate-source or IC supply pins below absolute maximum ratings during 10/1000 μs surges. |
| Low incremental surge resistance | Minimizes VC overshoot and ensures consistent clamping performance across production lots and temperature ranges. |
| MSL Level 1 moisture sensitivity | Allows unlimited floor life and standard reflow processing without baking; simplifies manufacturing logistics. |
| AEC-Q101 qualification path | HE3/HM3 variants are automotive-qualified; this E3/57T variant shares identical die and construction, supporting qualification traceability. |
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 |
|---|---|---|---|
| SMBJ16A-E3/52T | Lower PPPM (600 W), smaller SMB (DO-214AA) package, same VWM/VC specs. | Reduced surge handling; suitable only for lower-energy environments (e.g., consumer USB ports). | Select when board space is constrained and transient threat level is limited to IEC 61000-4-2 ±8 kV contact discharge. |
| SMCJ16CA-E3/57T | Bidirectional version with identical VWM, VC, and PPPM; no polarity marking; symmetrical clamping in both directions. | Required for AC-coupled or floating signal lines (e.g., RS-485, CAN bus) where voltage polarity reverses. | Choose only if bidirectional protection is mandated; unidirectional SMCJ16A-E3/57T offers superior cost and layout simplicity for DC rails. |
Compared with SMBJ16A-E3/52T, SMCJ16A-E3/57T delivers 2.5× higher surge energy absorption in the same footprint family; versus SMCJ16CA-E3/57T, it provides optimized clamping for polarized DC systems with tighter leakage control and lower cost.

FAQ
What is the breakdown voltage range for SMCJ16A-E3/57T?
The SMCJ16A-E3/57T has a guaranteed breakdown voltage (VBR) range of 17.8 V to 19.7 V at 1.0 mA test current, measured per ANSI/IEEE C62.35. This range ensures consistent avalanche initiation across temperature and process variation, and directly supports its 16 V stand-off rating with sufficient margin to avoid false triggering during normal operation.
Is SMCJ16A-E3/57T suitable for automotive applications?
SMCJ16A-E3/57T itself is commercial-grade (E3 suffix), but it shares identical die, package, and electrical characteristics with AEC-Q101-qualified variants (e.g., SMCJ16AHE3_A/H). Many Tier 1 suppliers accept E3-labeled SMCJ16A-E3/57T in non-safety-critical automotive modules when qualified via internal stress testing, leveraging its 150 °C TJmax and MSL Level 1 reflow compatibility.
How does the clamping voltage of SMCJ16A-E3/57T compare to its stand-off voltage?
The SMCJ16A-E3/57T maintains a 16 V stand-off voltage (VWM) and clamps to a maximum of 26.0 V at its rated 57.7 A peak pulse current. This 10.0 V differential ensures protected circuitry remains within safe operating limits during transients - for example, preserving the 30 V absolute maximum rating of common 24 V-rated MOSFETs and linear regulators.
What is the thermal resistance of SMCJ16A-E3/57T, and how does it affect layout?
SMCJ16A-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. To maintain TJ ≤150 °C at full 6.5 W steady-state dissipation, PCB layout must provide adequate copper area and avoid thermal bottlenecks - especially critical in sealed enclosures or high-ambient industrial settings.
Can SMCJ16A-E3/57T be used in bidirectional signal protection?
No - SMCJ16A-E3/57T is strictly unidirectional, with cathode marked by a band. For bidirectional protection (e.g., RS-485, CAN, audio lines), the SMCJ16CA-E3/57T variant must be used. Attempting to use SMCJ16A-E3/57T on AC or polarity-agnostic signals risks forward conduction, excessive leakage, or catastrophic failure during negative half-cycles.
