Product details
Overview
SMCJ16CA-E3/57T from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) in SMC (DO-214AB) package, designed for clamping voltage transients up to 1500 W peak pulse power with 26.0 V maximum clamping voltage at 57.7 A peak pulse current and 16 V standoff voltage. It protects sensitive ICs, MOSFETs, and sensor signal lines in automotive and industrial power electronics.
For engineers reviewing the SMCJ16CA-E3/57T datasheet, SMCJ16CA-E3/57T pinout, SMCJ16CA-E3/57T application, or SMCJ16CA-E3/57T equivalent, key selection criteria include bidirectional clamping capability, 1500 W PPPM rating, 16 V VWM, 17.8–19.7 V breakdown range at 1 mA, and AEC-Q101 qualification eligibility via HE3 suffix variants.
Technical Context
This device operates as a voltage-clamping protector using an avalanche diode structure, responding within picoseconds to transient overvoltages. Its bidirectional symmetry ensures identical clamping behavior in both polarities, with a 0.089 %/°C temperature coefficient of breakdown voltage and 1.0 μA max reverse leakage at 16 V.
Designed for PCB-level surge protection per IEC 61000-4-2/4-4/4-5, it sustains non-repetitive 10/1000 μs waveform surges up to 57.7 A while maintaining clamping below 26.0 V - critical for safeguarding 16 V rail interfaces without disrupting normal operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 16 V - maximum continuous reverse operating voltage before conduction begins |
| VBR min/max | 17.8 V / 19.7 V at 1 mA - guaranteed breakdown onset range for reliable triggering margin |
| VC @ IPPM | 26.0 V at 57.7 A - clamped voltage during 1500 W transient, limiting stress on downstream circuitry |
| PPPM | 1500 W - peak pulse power handling per 10/1000 μs waveform, defining surge robustness |
| ID @ VWM | 1.0 μA - ultra-low leakage ensuring minimal standby power loss and signal integrity |

Pinout & Package
SMCJ16CA-E3/57T uses the SMC (DO-214AB) package: a two-terminal, bidirectional device with no polarity marking. Terminals are matte tin-plated leads solderable per J-STD-002 and JESD 22-B102, mounted on 8.0 mm × 8.0 mm copper pads per terminal for thermal and surge performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient return path (bidirectional) | Completes low-impedance surge shunt path in either polarity; symmetric with cathode |
| Cathode | Transient return path (bidirectional) | Identical electrical role to anode; no functional distinction in CA-series devices |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating signal lines without polarity concerns |
| 1500 W peak pulse power | Withstands high-energy transients from inductive switching or ESD events in automotive power nets |
| Low clamping ratio (VC/VWM = 1.625) | Minimizes overvoltage overshoot during clamping, preserving margin for 16 V-rated components |
| AEC-Q101 qualification option | HE3/M3 suffix variants support automotive-grade reliability requirements including temperature cycling and humidity testing |
| MSL Level 1 (260 °C peak) | Compatible with standard lead-free reflow profiles without moisture sensitivity handling |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC16CA | Lower PPPM (600 W), same VWM (16 V), smaller SMA package | Reduced surge capacity; suitable only for lower-energy consumer-grade interfaces | Select when board space is constrained and surge threat level is limited to IEC 61000-4-2 ±8 kV contact |
| SMCJ16A-E3/57T | Unidirectional version; identical VWM, VC, and PPPM but asymmetric conduction | Requires correct polarity placement; unsuitable for AC or floating signals | Choose only if protecting DC rails with known polarity and no reverse-voltage risk |
Compared with SAC16CA and SMCJ16A-E3/57T, the SMCJ16CA-E3/57T uniquely delivers 1500 W bidirectional clamping in SMC package - essential for automotive and industrial systems where polarity-agnostic surge immunity and high-energy tolerance are mandatory.

FAQ
What is the maximum clamping voltage of SMCJ16CA-E3/57T at its rated peak pulse current?
The SMCJ16CA-E3/57T has a maximum clamping voltage (VC) of 26.0 V at its rated peak pulse current (IPPM) of 57.7 A under 10/1000 μs waveform conditions. This value is measured per JEDEC standards and defines the upper voltage limit imposed on protected circuits during worst-case surge events. The SMCJ16CA-E3/57T maintains this clamping performance across its full operating temperature range.
Is SMCJ16CA-E3/57T suitable for automotive applications?
Yes, the SMCJ16CA-E3/57T is compatible with automotive use cases due to its 1500 W surge rating, -55 °C to +150 °C operating temperature range, and MSL Level 1 reflow compatibility. While the base-E3 suffix is commercial grade, Vishay offers AEC-Q101 qualified versions under HE3 suffix (e.g., SMCJ16CAHE3_A/H). The SMCJ16CA-E3/57T itself meets mechanical and thermal requirements common in automotive subsystems.
How does the bidirectional design of SMCJ16CA-E3/57T affect its circuit placement?
The bidirectional design of SMCJ16CA-E3/57T eliminates polarity constraints - it can be placed across any two nodes without regard to anode/cathode orientation. This simplifies layout for AC-coupled lines, differential buses, or floating grounds where voltage polarity reversal may occur. Unlike unidirectional TVS diodes, the SMCJ16CA-E3/57T provides symmetrical clamping in both directions, making it ideal for protecting bidirectional data lines or transformer-coupled power rails.
What is the reverse leakage current specification for SMCJ16CA-E3/57T at its standoff voltage?
The SMCJ16CA-E3/57T exhibits a maximum reverse leakage current (ID) of 1.0 μA at its 16 V standoff voltage (VWM), measured at 25 °C. This ultra-low leakage preserves signal integrity in high-impedance sensor interfaces and minimizes quiescent power loss in always-on automotive modules. Leakage remains below 5 μA across the full -55 °C to +125 °C operating range, ensuring consistent performance in extreme environments.
Does SMCJ16CA-E3/57T require heatsinking for standard operation?
No, the SMCJ16CA-E3/57T does not require external heatsinking for transient suppression duty cycles, as its 1500 W rating applies to non-repetitive pulses. For continuous power dissipation, its 6.5 W rating at TA = 50 °C assumes mounting on 8.0 mm × 8.0 mm copper pads per terminal - standard PCB copper area suffices. Thermal resistance is 75 °C/W junction-to-ambient, so typical surge events do not elevate junction temperature beyond safe limits without added thermal mass.
