Product details
Overview
SMCJ5.0C-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 5.0 V stand-off voltage (VWM), 1500 W peak pulse power (PPPM), 9.2 V maximum clamping voltage (VC) at 163 A IPPM, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the SMCJ5.0C-E3/57T datasheet, SMCJ5.0C-E3/57T pinout, SMCJ5.0C-E3/57T application, or SMCJ5.0C-E3/57T equivalent, this device serves as a robust, surface-mount solution for protecting sensitive ICs, MOSFETs, and sensor signal lines against inductive switching surges and lightning-induced transients in automotive, industrial, and telecom systems.
Technical Context
The SMCJ5.0C-E3/57T operates as a bi-directional avalanche diode with symmetrical breakdown characteristics - minimum VBR of 6.40 V and maximum of 7.07 V at 10 mA test current. Its low incremental surge resistance enables rapid clamping response to 10/1000 µs transients without thermal runaway.
Designed for surface-mount assembly on 8.0 mm × 8.0 mm copper pads per terminal, it delivers 1500 W peak pulse power dissipation while maintaining TJ ≤ 150 °C and meeting MSL Level 1 reflow requirements (260 °C peak). The matte tin-plated leads comply with J-STD-002 and JESD 22-B102 solderability standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.0 V - Maximum reverse stand-off voltage before conduction; defines safe operating margin below clamping threshold. |
| VBR (min/max) | 6.40 V / 7.07 V at 10 mA - Ensures reliable bi-directional breakdown symmetry across production lots. |
| VC @ IPPM | 9.2 V at 163 A - Clamping voltage under 10/1000 µs surge; limits downstream voltage stress during ESD or load dump events. |
| PPPM | 1500 W - Peak pulse power handling capability; supports high-energy transient suppression without failure. |
| ID @ VWM | 1000 µA - Low leakage at rated stand-off voltage; minimizes standby power loss in battery-powered systems. |

Applications
| Automotive Power Line Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting LIN bus transceivers and microcontroller I/O pins from load-dump transients in 12 V vehicle electrical systems. IC Role / Device Role / Timing Role: Voltage clamping element placed between power rail and ground, activated only during overvoltage events. Use Value: Limits transient voltage to ≤9.2 V, preventing latch-up or gate oxide damage in 5 V logic devices. |
Use Scenario: Safeguarding analog output lines of pressure or temperature sensors in factory automation PLC modules. IC Role / Device Role / Timing Role: Bi-directional shunt protector on differential or single-ended signal paths exposed to EMI and relay switching noise. Use Value: Maintains signal integrity by clamping fast-rising transients (<1 ns rise time) while adding <1 pF parasitic capacitance. |
| Telecom Data Line Surge Suppression | Consumer Electronics USB Port Protection |
Use Scenario: Shielding RS-485 transceiver inputs in base station backhaul equipment from lightning-induced surges on outdoor cabling. IC Role / Device Role / Timing Role: Primary-level TVS placed at connector entry point, coordinated with secondary filtering components. Use Value: Absorbs up to 1500 W surge energy without degradation, preserving communication link uptime during thunderstorms. |
Use Scenario: Guarding USB 2.0 D+/D− lines in portable media players against human-body-model (HBM) ESD events. IC Role / Device Role / Timing Role: Fast-response clamping diode integrated into USB port ESD protection circuitry. Use Value: Responds in <1 ps to ±15 kV contact discharge, limiting voltage excursion to safe levels for USB PHY ICs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC5.0 | Lower PPPM (500 W), smaller SOD-123FL package, higher VC (14.5 V at 30 A) | Better suited for space-constrained consumer PCBs where surge energy is limited to IEC 61000-4-2 Level 4. | Select SAC5.0 when board area is critical and peak surge current remains below 30 A. |
| 1.5KE5.0C | Through-hole TO-218 package, same VWM/VC specs but higher thermal mass; not RoHS-compliant in legacy variants. | Preferred for high-reliability industrial power supplies requiring manual rework or wave-solder compatibility. | Choose 1.5KE5.0C only if through-hole mounting and legacy compliance override SMT automation needs. |
Compared with SMCJ5.0C-E3/57T, SAC5.0 trades surge capacity for miniaturization, while 1.5KE5.0C sacrifices surface-mount compatibility for mechanical ruggedness and legacy process support - neither offers pin-compatible replacement, and layout redesign is required for either alternative.

FAQ
What is the breakdown voltage range for SMCJ5.0C-E3/57T?
The SMCJ5.0C-E3/57T has a guaranteed breakdown voltage (VBR) range of 6.40 V to 7.07 V measured at 10 mA test current. This bi-directional specification applies equally in both polarities and ensures consistent clamping behavior regardless of transient direction - a key requirement for protecting floating or AC-coupled circuits where polarity cannot be assumed.
Is SMCJ5.0C-E3/57T suitable for automotive applications?
Yes, SMCJ5.0C-E3/57T is AEC-Q101 qualified and rated for operation from –55 °C to +150 °C, making it suitable for under-hood and cabin-mounted automotive electronics. Its 1500 W peak pulse power rating supports protection against ISO 7637-2 load-dump pulses and ISO 16750-2 supply transients - confirmed in Vishay's qualification report for the SMCJ family.
Does SMCJ5.0C-E3/57T have polarity markings?
No, SMCJ5.0C-E3/57T is a bi-directional TVS diode and carries no polarity marking on the package. The DO-214AB body is unmarked, reflecting its symmetrical internal structure - either terminal may connect to the protected line or ground without affecting functionality or clamping performance.
What is the maximum clamping voltage of SMCJ5.0C-E3/57T under surge conditions?
The SMCJ5.0C-E3/57T clamps to a maximum of 9.2 V when subjected to its rated peak pulse current (IPPM) of 163 A under the standardized 10/1000 µs waveform. This value is guaranteed across temperature and lifetime, ensuring downstream 5 V logic devices remain within absolute maximum ratings during surge events.
How does the SMCJ5.0C-E3/57T differ from the uni-directional SMCJ5.0A-E3/57T?
The SMCJ5.0C-E3/57T is bi-directional with symmetrical VBR and VC characteristics in both directions, whereas SMCJ5.0A-E3/57T is uni-directional and conducts only in reverse bias - requiring correct orientation during placement. The "C" suffix explicitly denotes bi-directional construction, validated by identical electrical specs in both polarities per Vishay Document 88394.
