Product details
Overview
SMCJ64C-E3/57T from Vishay General Semiconductor is a bi-directional transient voltage suppressor (TVS) diode in DO-214AB (SMCJ) package, designed for robust overvoltage protection on signal and power lines. It features a 64 V stand-off voltage (VWM), 103 V maximum clamping voltage (VC) at 14.6 A peak pulse current (IPPM), and 1500 W peak pulse power dissipation (PPPM) with 10/1000 µs waveform - ideal for safeguarding automotive sensor interfaces and industrial I/O circuits against ESD and inductive switching transients.
For engineers reviewing the SMCJ64C-E3/57T datasheet, SMCJ64C-E3/57T pinout, SMCJ64C-E3/57T application, or SMCJ64C-E3/57T equivalent, key selection criteria include verified bi-directional clamping performance, AEC-Q101 qualification for automotive use, RoHS-compliant matte tin terminations, and compatibility with automated SMT placement on standard 8.0 mm × 8.0 mm copper pads.
Technical Context
The SMCJ64C-E3/57T operates as a bi-directional avalanche diode, exhibiting symmetrical breakdown behavior in both polarities with minimum breakdown voltage (VBR) of 71.1 V and maximum of 78.6 V at 1 mA test current. Its low incremental surge resistance enables rapid voltage clamping during fast transients, while its thermal resistance (RθJA = 75 °C/W) supports reliable operation up to 150 °C junction temperature under defined PCB layout conditions.
Designed per ANSI/IEEE C62.35 standards, it delivers consistent 1500 W peak pulse power handling across ambient temperatures when derated above 25 °C, and meets J-STD-020 MSL Level 1 with 260 °C reflow peak - confirming suitability for high-reliability surface-mount assembly without moisture sensitivity concerns.

FAQ
What is the clamping voltage of SMCJ64C-E3/57T and how is it measured?
The SMCJ64C-E3/57T has a maximum clamping voltage (VC) of 103 V, measured at 14.6 A peak pulse current (IPPM) using a standardized 10/1000 µs double-exponential waveform. This value represents the highest voltage the device allows across its terminals during a transient event, ensuring downstream components remain within safe operating limits. The test condition is explicitly defined in the Vishay datasheet document 88394 and applies equally in both directions due to its bi-directional design.
Is SMCJ64C-E3/57T qualified for automotive applications?
Yes, SMCJ64C-E3/57T is AEC-Q101 qualified, as confirmed in the Vishay datasheet revision 11-Dec-12 (document 88394). This qualification validates its reliability under automotive-grade temperature cycling, humidity, mechanical shock, and lifetime surge testing - making it suitable for use in engine control units, ADAS sensors, body electronics, and infotainment systems where component failure could impact vehicle safety or functionality.
Does SMCJ64C-E3/57T have polarity markings on the package?
No, SMCJ64C-E3/57T does not have polarity markings because it is a bi-directional TVS diode. Unlike uni-directional variants (e.g., SMCJ64A), the CA suffix indicates symmetrical breakdown behavior in both directions, so neither terminal is designated anode or cathode in functional terms. The device may be installed in either orientation on the PCB without affecting performance or protection capability.
What is the thermal resistance of SMCJ64C-E3/57T and how does it affect layout?
The SMCJ64C-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 Vishay datasheet. This value assumes minimal PCB copper area; increasing pad size or adding internal ground planes reduces thermal resistance and improves power handling. Layout must follow the recommended mounting pad dimensions to achieve rated 1500 W pulse power and avoid thermal runaway during repeated surges.
What does the "E3/57T" suffix mean in SMCJ64C-E3/57T?
The "E3" suffix denotes RoHS-compliant, commercial-grade construction with matte tin-plated leads meeting J-STD-002 solderability and JESD 201 Class 1A whisker resistance. The "57T" indicates packaging in 7-inch diameter plastic tape and reel, with a base quantity of 850 units per reel - optimized for automated SMT placement equipment. This ordering code distinguishes it from alternate packaging formats like 9AT (13-inch reel, 3500 units) or HE3 variants (AEC-Q101 qualified).
