Product details
Overview
SMCJ5.0A-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 5.0 V DC power rails and signal lines. It delivers 1500 W peak pulse power (10/1000 μs), clamps at ≤9.2 V under 163 A surge current, and features 6.40–7.07 V breakdown voltage at 10 mA test current - ideal for protecting USB ports, microcontroller I/O, and automotive sensor interfaces.
For engineers reviewing the SMCJ5.0A-E3/57T datasheet, SMCJ5.0A-E3/57T pinout, SMCJ5.0A-E3/57T application, or SMCJ5.0A-E3/57T equivalent, key selection criteria include its 5.0 V stand-off voltage, 9.2 V max clamping voltage at rated IPPM, unidirectional polarity with cathode band marking, RoHS-compliant matte tin terminals, and MSL Level 1 reflow compatibility up to 260 °C.
Technical Context
The SMCJ5.0A-E3/57T operates as a silicon avalanche diode, leveraging glass-passivated junction technology for stable breakdown behavior and low incremental surge resistance. Its response time is sub-nanosecond, enabling suppression of fast ESD and lightning-induced transients before downstream ICs are damaged.
It is rated for -55 °C to +150 °C operating junction temperature, with thermal resistance RθJA = 75 °C/W and RθJL = 15 °C/W, requiring minimum 8.0 mm × 8.0 mm copper pads per terminal for full 1500 W rating per JEDEC standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.0 V - Maximum continuous reverse working voltage; defines safe DC operating limit before leakage rises significantly |
| VBR min/max | 6.40 V / 7.07 V at IT = 10 mA - Confirmed breakdown range ensures reliable turn-on during overvoltage events |
| VC @ IPPM | ≤9.2 V at 163 A - Clamping voltage under full 1500 W surge; determines maximum stress on protected circuitry |
| PPPM | 1500 W (10/1000 μs waveform) - Peak transient energy handling capacity for industrial-grade surge immunity |
| IFSM | 200 A (8.3 ms half-sine) - Surge current rating for unidirectional forward conduction during fault conditions |
| TJ max | +150 °C - Maximum junction temperature; supports operation in under-hood automotive and high-ambient industrial environments |
| Package | SMC (DO-214AB) - Standardized 2-pin surface-mount outline with 7.75 mm × 6.22 mm body and 2.06 mm height |
Pinout & Package
SMCJ5.0A-E3/57T uses the SMC (DO-214AB) package: a rectangular, low-profile, surface-mount case with two coplanar matte tin-plated leads. Polarity is marked by a cathode band on the body end; the banded terminal is cathode (K), the opposite is anode (A). Mounting requires 8.0 mm × 8.0 mm copper pads per lead for full power derating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Positive reference terminal for unidirectional conduction | Connected to system ground or lower-potential rail; conducts during reverse-biased transient clamp |
| Cathode (K) | Negative reference terminal; marked with band | Connected to protected line (e.g., 5 V supply); avalanche breakdown occurs when K-to-A voltage exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable, repeatable breakdown voltage and long-term reliability under repeated surge stress |
| MSL Level 1 rating | Enables single-reflow assembly without moisture sensitivity concerns; peak reflow temperature up to 260 °C |
| Low incremental surge resistance | Minimizes clamping voltage overshoot during fast transients, improving protection margin for 3.3 V/5 V logic |
| AEC-Q101 qualified variant available | HE3 suffix versions meet automotive qualification for engine control, ADAS sensors, and infotainment power rails |
| UL 497B recognized | Validated for telecom and industrial surge protection systems requiring safety agency compliance |

| Industrial PLC Digital Input | Consumer Power Adapter Output |
Use Scenario: Shielding 24 V digital input channels from inductive kickback when switching solenoids or relays in factory automation systems. IC Role / Device Role / Timing Role: Unidirectional TVS connected between input terminal and common ground, absorbing repetitive 10/1000 μs transients. Use Value: Low 75 °C/W RθJA enables thermal stability on standard PCB layouts; 1000 μA max leakage at 5.0 V avoids false triggering in high-impedance sensing circuits. | Use Scenario: Secondary-side transient suppression on 5 V output of wall-mounted AC/DC adapters used in smart home hubs and IoT gateways. IC Role / Device Role / Timing Role: Final-stage protection device after DC-DC converter, guarding against output short-circuit recovery spikes and external EFT. Use Value: RoHS-compliant E3 suffix meets global regulatory requirements; DO-214AB footprint allows automated placement and high-volume manufacturing scalability. |
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 SMA package, higher VC (11.5 V) | Not suitable for 1500 W surge environments; limited to low-energy consumer interfaces | Select only if board space is constrained and surge threat level is below IEC 61000-4-5 Level 2 |
| 1.5SMC5.0A | Same SMC package, identical VWM/VBR, but rated for 1500 W with tighter VC tolerance (≤9.0 V) | Offers marginally better clamping performance; same thermal and layout compatibility | Preferred where <0.2 V clamping reduction improves system-level immunity margin |
Compared with SAC5.0 and 1.5SMC5.0A, the SMCJ5.0A-E3/57T provides verified 1500 W surge capability in a standardized SMC footprint, with documented 9.2 V clamping ceiling and AEC-Q101-qualified variants - making it the robust choice for industrial and automotive power rail protection where sustained transient energy must be absorbed without degradation.

FAQ
What is the maximum clamping voltage of the SMCJ5.0A-E3/57T under full-rated surge current?
The SMCJ5.0A-E3/57T has a maximum clamping voltage (VC) of 9.2 V when subjected to its rated peak pulse current (IPPM) of 163 A using a 10/1000 μs waveform. This value is measured at TA = 25 °C on specified 8.0 mm × 8.0 mm copper pads and defines the upper voltage limit imposed on protected circuitry during worst-case transient events. The SMCJ5.0A-E3/57T maintains this clamping performance across its full operating temperature range.
Is the SMCJ5.0A-E3/57T suitable for automotive applications?
Yes - while the base SMCJ5.0A-E3/57T is commercial-grade, Vishay offers AEC-Q101-qualified variants under ordering codes like SMCJ5.0AHE3_A/H. These versions undergo rigorous stress testing for automotive use, including temperature cycling, humidity bias, and surge endurance. The SMCJ5.0A-E3/57T itself shares identical electrical characteristics and SMC package dimensions, enabling drop-in qualification upgrades. Its +150 °C TJ max and UL 497B recognition further support automotive deployment.
How does the SMCJ5.0A-E3/57T differ from bidirectional TVS diodes like SMCJ5.0CA?
The SMCJ5.0A-E3/57T is unidirectional and functions as a polarity-sensitive clamp - conducting only when cathode voltage exceeds anode by ≥VBR. In contrast, SMCJ5.0CA is bidirectional, providing symmetrical clamping for AC signals or floating lines. The SMCJ5.0A-E3/57T exhibits lower leakage (<1000 μA at 5.0 V) and supports forward surge current (IFSM = 200 A), unlike bidirectional types. Its cathode band marking also simplifies PCB layout verification. The SMCJ5.0A-E3/57T is preferred for DC power rail protection where polarity is fixed.
What is the thermal resistance and recommended pad layout for the SMCJ5.0A-E3/57T?
The SMCJ5.0A-E3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W and junction-to-lead (RθJL) of 15 °C/W. To achieve full 1500 W peak pulse power rating, Vishay specifies mounting on minimum 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal, with internal thermal vias recommended for sustained surge duty. The SMCJ5.0A-E3/57T's SMC (DO-214AB) package supports standard reflow profiles up to 260 °C peak.
Does the SMCJ5.0A-E3/57T require additional series impedance for optimal protection?
No - the SMCJ5.0A-E3/57T is designed for direct connection between protected line and ground (or rail), with no mandatory series resistor. However, in high-speed data lines (e.g., USB), a small series resistor (e.g., 1–10 Ω) may be added to damp resonance and reduce ringing without compromising clamping speed. The SMCJ5.0A-E3/57T's sub-nanosecond response ensures effective suppression regardless; its low incremental surge resistance minimizes voltage overshoot even without external impedance.
