Product details
Overview
SMCJ5.0-E3/57T from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-214AB (SMCJ) package, designed for robust overvoltage protection of sensitive electronics. It features a 5.0 V stand-off voltage (VWM), 6.40–7.07 V breakdown voltage (VBR) at 10 mA, 1500 W peak pulse power (10/1000 µs), 163 A peak pulse current (IPPM), and clamps to ≤9.2 V at rated surge. It is widely deployed in automotive power supply rails and industrial sensor interfaces.
For engineers reviewing the SMCJ5.0-E3/57T datasheet, SMCJ5.0-E3/57T pinout, SMCJ5.0-E3/57T application, or SMCJ5.0-E3/57T equivalent, key selection criteria include unidirectional polarity, 1500 W surge rating, DO-214AB thermal performance (RθJA = 75 °C/W), AEC-Q101 qualification, and RoHS-compliant matte tin plating per J-STD-002.
Technical Context
The SMCJ5.0-E3/57T operates as a silicon avalanche diode with glass-passivated junction, delivering sub-nanosecond response to transients. Its clamping behavior is defined by a low incremental surge resistance and stable VBR tolerance (±5% typical), enabling predictable protection under repetitive 10/1000 µs surges up to 1500 W.
Designed for surface-mount placement on 8.0 mm × 8.0 mm copper pads, it supports automated assembly and meets MSL Level 1 (260 °C peak reflow). The cathode band marking indicates polarity, and its 150 °C max junction temperature ensures reliability in under-hood automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.0 V - Maximum reverse working voltage before conduction begins; defines safe operating margin below breakdown |
| VBR min/max | 6.40 V / 7.07 V at 10 mA - Confirmed avalanche onset range; ensures consistent triggering across production lots |
| VC @ IPPM | ≤9.2 V at 163 A - Clamped voltage during full-rated 10/1000 µs surge; limits stress on downstream ICs |
| PPPM | 1500 W - Peak pulse power handling per standard waveform; enables protection against IEC 61000-4-5 Level 4 surges |
| IFSM | 200 A - Non-repetitive forward surge rating (8.3 ms half-sine); supports load dump survival in 12 V systems |
| TJ max | +150 °C - Maximum junction temperature; allows operation in engine control units and power converters |
| RθJA | 75 °C/W - Thermal resistance junction-to-ambient on recommended pad layout; informs heatsinking requirements |
Pinout & Package

Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per stress test plan |
| Glass-passivated junction | Ensures stable VBR and low leakage (<1000 µA at VWM) across humidity and thermal aging |
| MSL Level 1 | Zero moisture sensitivity; supports standard SMT reflow without baking or special handling |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., ISO 7637-2 pulse 1/2a/5a) |
| RoHS-compliant E3 suffix | Meets JEDEC JESD201 Class 1A whisker resistance; suitable for high-reliability industrial PCBs |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs from load dump and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power rail and chassis ground to clamp surges above 5.0 V. Use Value: Withstands 200 A IFSM and clamps to ≤9.2 V, preventing damage to MCU power supplies and CAN transceivers. | Use Scenario: Shielding analog sensor outputs (e.g., pressure, temperature) from ESD and inductive switching noise. IC Role / Device Role / Timing Role: TVS connected across signal line and ground to absorb ±8 kV contact ESD per IEC 61000-4-2. Use Value: Sub-ns response and 1500 W PPPM ensure signal integrity remains intact during transient events. |
| Consumer Power Adapter Input Stage | Telecom DC Power Feed Protection |
Use Scenario: Safeguarding AC/DC adapter primary-side rectifier and controller ICs from lightning-induced surges. IC Role / Device Role / Timing Role: Placed across bulk capacitor input to divert line-to-ground transients before they reach switching FETs. Use Value: 1500 W rating and 75 °C/W RθJA allow sustained surge handling without thermal runaway in compact enclosures. | Use Scenario: Protecting PoE-powered equipment (e.g., IP cameras) from induced surges on 48 V DC feed lines. IC Role / Device Role / Timing Role: Unidirectional TVS on each DC pair relative to common-mode ground reference. Use Value: Precise 5.0 V VWM aligns with 48 V system derating margins, while 9.2 V VC prevents latch-up in powered devices. |
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), same VWM (5.0 V), smaller DO-214AC (SMA) package | Limited to lower-energy transients; unsuitable for IEC 61000-4-5 Level 4 or automotive load dump | Select when board space is constrained and surge energy is <500 W |
| 1.5KE5.0A | Higher VBR (6.4–7.0 V), same VWM, axial-leaded DO-15 package, 1500 W rating | Not surface-mount; requires through-hole assembly and larger PCB footprint | Select for legacy through-hole designs or prototyping where reflow compatibility is not required |
Compared with SAC5.0 and 1.5KE5.0A, the SMCJ5.0-E3/57T delivers identical clamping performance in a compact, AEC-Q101-qualified SMT package optimized for automated manufacturing and high-energy surge immunity in automotive and industrial systems.

FAQ
What is the maximum clamping voltage of the SMCJ5.0-E3/57T under full-rated surge conditions?
The SMCJ5.0-E3/57T clamps to a maximum of 9.2 V when subjected to its rated 163 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured at the device terminals and reflects worst-case voltage seen by downstream circuitry during surge events, ensuring compatibility with 5 V logic and power rails.
Is the SMCJ5.0-E3/57T suitable for automotive applications?
Yes, the SMCJ5.0-E3/57T is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments. Its 150 °C maximum junction temperature, 200 A IFSM rating for load dump survival, and MSL Level 1 reflow compatibility make it appropriate for engine control modules, body controllers, and ADAS sensor power supplies.
Does the SMCJ5.0-E3/57T have bidirectional capability?
No, the SMCJ5.0-E3/57T is a unidirectional TVS diode. Its cathode band marking confirms polarity-sensitive operation. For bidirectional protection, Vishay offers the SMCJ5.0CA variant, which has symmetric clamping in both directions and no polarity marking.
What is the thermal resistance of the SMCJ5.0-E3/57T, and how does it affect layout?
The SMCJ5.0-E3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on the recommended 8.0 mm × 8.0 mm copper pads per terminal. To maintain safe junction temperatures during repeated surges, PCB layout must replicate this pad area and avoid excessive trace length or isolation that increases thermal impedance.
How does the E3/57T suffix impact compliance and packaging of the SMCJ5.0-E3/57T?
The E3 suffix denotes RoHS compliance and JESD201 Class 1A whisker resistance; the 57T indicates 7-inch tape-and-reel packaging with 850 units per reel. This configuration ensures compatibility with high-speed pick-and-place machines and meets environmental and reliability requirements for industrial and automotive production lines.
