Product details
Overview
SMCJ6.0A-M3/57T from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for clamping fast voltage transients up to 1500 W peak pulse power (10/1000 µs), with 6.67–7.37 V breakdown voltage at 10 mA, 6.0 V stand-off voltage, and 10.3 V maximum clamping voltage at 145.6 A surge current. It protects MOSFETs, ICs, and sensor signal lines in automotive and industrial power electronics.
For engineers reviewing the SMCJ6.0A-M3/57T datasheet, SMCJ6.0A-M3/57T pinout, SMCJ6.0A-M3/57T application, or SMCJ6.0A-M3/57T equivalent, key selection criteria include unidirectional polarity, 1500 W PPPM rating, 10.3 V VC at rated IPPM, M3 halogen-free RoHS compliance, and SMC package thermal performance with RθJA = 75 °C/W.
Technical Context
This device operates as a clamping-type overvoltage protector using an avalanche junction. Its glass-passivated chip enables sub-nanosecond response time and low incremental surge resistance, critical for suppressing ESD and inductive switching spikes on DC power rails and low-voltage signal paths.
Rated for -55 °C to +150 °C junction temperature, it meets J-STD-020 MSL Level 1 and supports automated SMT placement. The cathode band identifies polarity; no marking is used on bidirectional variants - but SMCJ6.0A-M3/57T is explicitly unidirectional per ordering code and electrical table.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 6.67–7.37 V at 10 mA - defines minimum voltage at which avalanche conduction begins; ensures reliable triggering above normal 6.0 V rail. |
| Stand-off Voltage VWM | 6.0 V - maximum continuous reverse voltage before leakage exceeds 1000 μA; matches nominal 6 V supply systems. |
| Clamping Voltage VC | 10.3 V at 145.6 A (10/1000 µs) - limits transient voltage seen by protected circuit; stays below typical 12 V IC absolute max ratings. |
| Peak Pulse Power PPPM | 1500 W - energy-handling capacity for standardized surge waveforms; supports IEC 61000-4-5 Level 4 immunity design. |
| Junction Temperature Range | -55 °C to +150 °C - enables operation in under-hood automotive and industrial environments without derating. |
| Package | SMC (DO-214AB) - 7.75 mm × 6.22 mm footprint with 2.62 mm height; optimized for thermal dissipation on 8 mm × 8 mm copper pads. |
| RoHS Compliance | M3 suffix - halogen-free, RoHS-compliant, commercial-grade; satisfies IPC-1752A material declaration requirements. |
Pinout & Package
SMCJ6.0A-M3/57T uses the standard SMC (DO-214AB) surface-mount package: two-terminal, unidirectional configuration with cathode identified by a band on the body. Mounting requires 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal for rated power dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection point | Connected to ground or return path; carries full surge current during clamping event. |

IC Role / Device Role / Timing Role: Standoff protection element on 4–20 mA loop outputs, placed before signal conditioning amplifier inputs. Use Value: Sub-ns response prevents latch-up in op-amps; 6.0 V VWM avoids interference with 5 V reference-based sensor excitation. |
| Consumer DC Adapter Input Protection | Telecom DC Feeder Protection |
Use Scenario: Guards primary-side input of 6 V wall adapters against AC line transients coupled through transformer leakage inductance. IC Role / Device Role / Timing Role: First-line transient suppressor across bulk capacitor input, upstream of rectifier and controller IC. Use Value: 1500 W PPPM handles repeated 1 kV/500 A surges per IEC 61000-4-5; low clamping preserves input capacitor voltage rating margin. |
Use Scenario: Protects -48 V DC feeder lines in telecom base station remote radio units from lightning-induced surges. IC Role / Device Role / Timing Role: Reverse-polarity configured TVS (cathode to -48 V rail) to clamp positive-going transients toward ground. Use Value: 10.3 V VC ensures downstream DC/DC converters see < 39 V during surge - well within 40 V input rating of common PMBus controllers. |
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-M3/57T | Lower PPPM (400 W), smaller SMA package (DO-214AC), higher RθJA (110 °C/W) | Restricted to lower-energy transients; unsuitable for IEC 61000-4-5 Level 4 or ISO 7637-2 Pulse 5a | Select when board space is constrained and surge threat level is limited to ESD or low-energy switching noise. |
| SMCJ6.0CA-M3/57T | Bidirectional variant; same VBR (6.67–7.37 V), identical PPPM and VC, but symmetric clamping in both polarities | Required for AC-coupled or floating signal lines where polarity reversal may occur (e.g., RS-485, CAN bus) | Choose only if bidirectional protection is mandated; otherwise unidirectional SMCJ6.0A-M3/57T offers better cost and layout simplicity. |

FAQ
What is the maximum clamping voltage of the SMCJ6.0A-M3/57T at its rated peak pulse current?
The SMCJ6.0A-M3/57T has a maximum clamping voltage (VC) of 10.3 V at its rated peak pulse current (IPPM) of 145.6 A, measured under the standard 10/1000 µs waveform. This value is guaranteed per Vishay's datasheet revision 09-Jan-2024 (Document Number: 88394) and defines the upper voltage limit imposed on protected circuits during surge events. Maintaining VC below 12 V ensures compatibility with common 6 V and 12 V logic and power ICs.
Is the SMCJ6.0A-M3/57T suitable for automotive applications?
Yes, the SMCJ6.0A-M3/57T is suitable for automotive applications as a commercial-grade TVS diode, and an AEC-Q101 qualified version (e.g., SMCJ6.0A-HM3/57T) is available. While the M3 suffix itself denotes halogen-free RoHS compliance-not AEC-Q101-the underlying SMCJ platform supports automotive qualification. Designers must specify the HM3 or HE3 suffix for AEC-Q101; the SMCJ6.0A-M3/57T remains ideal for non-safety-critical 6 V subsystems like body control modules and infotainment power rails.
How does the SMCJ6.0A-M3/57T differ from the SMCJ6.0CA-M3/57T?
The SMCJ6.0A-M3/57T is unidirectional, with polarity marked by a cathode band and intended for DC line protection where voltage polarity is fixed. In contrast, the SMCJ6.0CA-M3/57T is bidirectional, lacking polarity marking and providing symmetrical clamping for AC or floating signals. Both share identical breakdown (6.67–7.37 V), clamping (10.3 V), and power (1500 W) specs, but the unidirectional SMCJ6.0A-M3/57T offers lower junction capacitance and simpler layout integration in DC applications.
What is the thermal resistance of the SMCJ6.0A-M3/57T, and how does it affect PCB layout?
The SMCJ6.0A-M3/57T 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. This value assumes minimum recommended pad layout per Vishay's datasheet. To maintain safe junction temperatures under repetitive surge conditions, designers must allocate adequate copper area and avoid excessive trace length or isolation - undersized pads increase RθJA and risk thermal runaway during sustained transient activity.
Does the SMCJ6.0A-M3/57T meet lead-free and halogen-free compliance standards?
Yes, the SMCJ6.0A-M3/57T carries the M3 suffix, indicating it is halogen-free and RoHS-compliant per EU Directive 2011/65/EU, with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. It also passes JESD 201 Class 2 whisker testing. This makes the SMCJ6.0A-M3/57T suitable for environmentally regulated industries including automotive, medical, and industrial automation where material declarations (e.g., IPC-1752A) are required.
