Product details
Overview
SMCG6.0HE3/57T from Vishay General Semiconductor is a bi-directional transient voltage suppressor (TVS) diode in DO-215AB (SMCG) package, designed for clamping voltage transients on signal and power lines. It features 6.0 V stand-off voltage (VWM), 1500 W peak pulse power (PPPM), 10.3 V maximum clamping voltage (VC) at 145.6 A IPPM, and AEC-Q101 qualification for automotive use.
For engineers reviewing the SMCG6.0HE3/57T datasheet, SMCG6.0HE3/57T pinout, SMCG6.0HE3/57T application, or SMCG6.0HE3/57T equivalent, key selection criteria include bi-directional surge clamping capability, low clamping ratio (VC/VWM = 1.72), RoHS-compliant AEC-Q101 qualification, and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads.
Technical Context
This device operates as a bi-directional avalanche diode, responding to both positive and negative transients without polarity marking. Its glass-passivated junction ensures stable breakdown behavior and low incremental surge resistance under 10/1000 µs waveform stress.
Thermal performance is defined by RθJA = 75 °C/W and RθJL = 15 °C/W, enabling reliable operation up to TJ = +150 °C. The DO-215AB package meets UL 94 V-0 flammability rating and supports MSL Level 1 handling per J-STD-020 at 260 °C peak reflow.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 6.0 V - Maximum continuous reverse voltage before clamping begins; defines operating margin for protected circuitry. |
| VC @ IPPM | 10.3 V at 145.6 A - Clamped voltage during 10/1000 µs surge; determines worst-case overvoltage seen by downstream ICs. |
| PPPM | 1500 W - Peak transient energy absorption capacity; enables protection against IEC 61000-4-5 Level 4 surges. |
| ID @ VWM | 1000 µA - Reverse leakage at rated stand-off; low enough to avoid loading sensitive sensor or communication lines. |
| TJ max. | +150 °C - Maximum junction temperature; supports under-hood automotive environments and industrial high-temp PCB layouts. |
| Qualification | AEC-Q101 qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing. |
Pinout & Package
DO-215AB (SMCG) surface-mount package with gull-wing leads; matte tin-plated terminals compliant with J-STD-002 and JESD 22-B102 solderability standards. Bi-directional construction means no polarity marking - both terminals are electrically symmetric.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Bi-directional avalanche junction - conducts equally in either direction when V > VC; no cathode band marking. |
| Lead 1 / Lead 2 | PCB interconnect interface | Gull-wing terminations enable automated placement and reflow; 0.220–0.245 inch lead span accommodates standard SMT footprints. |
Key Features
| Feature | Design Value |
|---|---|
| Bi-directional clamping | Enables single-device protection of AC-coupled or differential signal lines (e.g., CAN, LIN, RS-485) without polarity concerns. |
| 1500 W peak pulse power | Withstands 10/1000 µs surges up to 145.6 A - sufficient for ISO 7637-2 Pulse 1/2a/3a and IEC 61000-4-5 Combination Wave (1.2/50 µs + 8/20 µs). |
| AEC-Q101 qualification | Validated for automotive electronics including engine control units, body controllers, and ADAS sensors requiring long-term field reliability. |
| MSL Level 1 rating | Allows unlimited floor life and peak reflow up to 260 °C - eliminates baking requirements and simplifies manufacturing flow. |
| UL 94 V-0 molding compound | Ensures flame-retardant PCB assembly compliance for safety-critical automotive and industrial end equipment. |
Applications
| Automotive Power Line Protection | Industrial Sensor Interface Protection |
|---|---|
|
Use Scenario: Protecting 12 V battery-fed ECUs from load dump and alternator transients per ISO 7637-2. IC Role / Device Role / Timing Role: Primary clamping element placed at board-level input filter stage, upstream of DC/DC converters and microcontrollers. Use Value: Limits transient overshoot to ≤10.3 V, preventing latch-up or gate oxide damage in downstream 16 V-rated power management ICs. |
Use Scenario: Safeguarding analog output lines (e.g., 4–20 mA current loops) in PLC I/O modules exposed to field wiring surges. IC Role / Device Role / Timing Role: Parallel-connected TVS across signal path to shunt induced energy before reaching precision DACs or op-amps. Use Value: Sub-100 ns response time clamps fast-rising transients (<1 kV/µs), preserving signal integrity and avoiding ADC saturation. |
| Automotive CAN Bus Protection | Consumer Audio Signal Line Protection |
|
Use Scenario: Shielding high-speed CAN FD transceivers (e.g., TJA1044) from ESD and coupled noise in vehicle networking. IC Role / Device Role / Timing Role: Bi-directional TVS placed differentially across CANH/CANL lines, leveraging symmetry for balanced clamping. Use Value: Matches CAN bus impedance profile while maintaining <1 pF junction capacitance - avoids signal edge degradation at 5 Mbps. |
Use Scenario: Preventing ESD damage to line-in/out jacks and codec inputs in smart speakers and AV receivers. IC Role / Device Role / Timing Role: Low-leakage (1000 µA) TVS mounted directly at connector entry point to divert human-body-model (HBM) discharges. Use Value: 6.0 V VWM aligns with typical audio rail voltages, ensuring no false triggering during normal ±5 V signal swings. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.0A-E3/52T | Uni-directional; 6.4–7.07 V VBR range; 1000 W PPPM; SMA package (DO-214AC); higher RθJA (110 °C/W). | Requires polarity-aware layout; lower surge rating limits use in high-energy automotive load dump scenarios. | Select only if uni-directional protection suffices and space constraints favor smaller SMA footprint. |
| 1.5KE6.8CA | Through-hole DO-201 package; 6.8–7.5 V VBR; 1500 W PPPM; no AEC-Q101 qualification; higher mounting thermal resistance. | Not suitable for automated SMT production or under-hood automotive environments due to leaded construction and qualification gap. | Consider only for legacy through-hole designs where rework tolerance and manual assembly are acceptable. |
Compared with SMAJ6.0A-E3/52T and 1.5KE6.8CA, SMCG6.0HE3/57T delivers bi-directional operation in a compact, AEC-Q101-qualified SMT package with superior thermal performance (RθJL = 15 °C/W) - making it optimal for modern automotive and industrial PCBs requiring zero-polarity design and high-volume assembly.

FAQ
What is the clamping voltage of SMCG6.0HE3/57T and how is it measured?
The SMCG6.0HE3/57T has a maximum clamping voltage (VC) of 10.3 V at 145.6 A peak pulse current (IPPM), tested with a 10/1000 µs waveform per ANSI/IEEE C62.35. This value represents the upper limit of voltage imposed on protected circuitry during surge events and is verified under standardized conditions using 8.0 mm × 8.0 mm copper pads per terminal.
Is SMCG6.0HE3/57T suitable for automotive applications?
Yes, SMCG6.0HE3/57T is AEC-Q101 qualified and explicitly rated for automotive use. Its DO-215AB package supports MSL Level 1 handling, its junction temperature range extends to +150 °C, and its 1500 W PPPM rating meets ISO 7637-2 load dump and pulse test requirements - making it appropriate for engine control, body electronics, and ADAS subsystems.
Does SMCG6.0HE3/57T have polarity markings?
No, SMCG6.0HE3/57T is a bi-directional TVS diode and carries no cathode band or polarity marking. Both terminals are functionally identical, allowing flexible placement across AC-coupled or differential signal paths such as CAN, LIN, or RS-485 without orientation constraints.
What is the leakage current specification for SMCG6.0HE3/57T at its stand-off voltage?
At the rated stand-off voltage (VWM) of 6.0 V, SMCG6.0HE3/57T exhibits a maximum reverse leakage current (ID) of 1000 µA at TA = 25 °C. This low leakage ensures minimal impact on high-impedance sensor outputs or battery-powered circuits where quiescent current must be tightly controlled.
How does the thermal resistance of SMCG6.0HE3/57T affect PCB layout?
SMCG6.0HE3/57T has RθJA = 75 °C/W and RθJL = 15 °C/W. To maintain safe junction temperatures, PCB layout must use minimum 8.0 mm × 8.0 mm copper pads per terminal as specified in the datasheet. Reducing pad area increases thermal resistance and risks exceeding TJ max. = +150 °C under repeated surge conditions.
