Product details
Overview
SMCG6.0CAHE3/57T from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in the SMCG (DO-215AB) surface-mount package, designed for clamping voltage transients on signal or power lines. It features a 6.0 V stand-off voltage (VWM), 6.67–7.37 V breakdown voltage (VBR) at 10 mA, 1500 W peak pulse power (10/1000 µs), <10.3 V clamping voltage at 145.6 A IPPM, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the SMCG6.0CAHE3/57T datasheet, SMCG6.0CAHE3/57T pinout, SMCG6.0CAHE3/57T application, or SMCG6.0CAHE3/57T equivalent, this device is selected for robust ESD and surge protection in automotive sensor interfaces, industrial I/O lines, and telecom power rails where bidirectional clamping, low leakage (<1000 µA at VWM), and MSL Level 1 reflow compatibility are required.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with identical VBR min/max and clamping behavior in either direction. Its glass-passivated junction ensures stable leakage and fast response (<1 ns), while the DO-215AB package provides low thermal resistance (RθJL = 15 °C/W) and supports automated placement.
The device complies with ANSI/IEEE C62.35 for surge testing and meets UL 497B recognition (QVGQ2). It is rated for -55 °C to +150 °C operating junction temperature and derates linearly above 25 °C ambient per Figure 2 in the datasheet.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum continuous reverse working voltage before clamping begins; defines safe operating margin below breakdown. |
| VBR (min/max) | 6.67 V / 7.37 V at 10 mA - Confirmed breakdown threshold range; ensures predictable turn-on during transients. |
| VC @ IPPM | 10.3 V at 145.6 A - Clamped voltage under 10/1000 µs surge; limits downstream IC stress to safe levels. |
| PPPM | 1500 W - Peak pulse power handling capability; supports high-energy lightning or inductive-switching surges. |
| ID @ VWM | ≤1000 µA - Low reverse leakage at stand-off voltage; minimizes quiescent power loss in battery-powered systems. |

Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN, LIN, or analog sensor inputs (e.g., temperature, pressure) from load-dump and ESD events in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional clamping element placed directly at connector or IC input pins to shunt transients before they reach sensitive circuitry. Use Value: Limits clamped voltage to ≤10.3 V during 145.6 A surges, preserving signal integrity and preventing latch-up in 3.3 V/5 V sensor interface ICs. |
Use Scenario: Safeguarding digital input/output channels on programmable logic controllers exposed to inductive switching noise from solenoids and relays. IC Role / Device Role / Timing Role: Primary surge suppression device on field-side PCB traces, mounted adjacent to terminal blocks. Use Value: Absorbs 1500 W pulses without degradation, enabling reliable operation in harsh factory environments with frequent 24 V DC switching transients. |
| Telecom Power Line Protection | Consumer USB Interface Protection |
Use Scenario: Guarding 12 V or 48 V DC power feeds in VoIP gateways and base station backhaul equipment against lightning-induced surges. IC Role / Device Role / Timing Role: Secondary-stage TVS deployed after primary GDT or MOV, providing precise low-clamp protection for DC-DC converters. Use Value: Clamps to 10.3 V within nanoseconds, preventing overvoltage damage to isolated DC-DC controller ICs rated for ≤16 V input. |
Use Scenario: ESD and surge protection for USB 2.0 data lines (D+/D−) and VBUS in portable docking stations and smart hubs. IC Role / Device Role / Timing Role: Bidirectional TVS placed inline with differential pairs to suppress ±8 kV contact ESD per IEC 61000-4-2. Use Value: Delivers <1000 µA leakage at 6.0 V, avoiding signal attenuation or timing skew on high-speed USB signals. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.0A-E3/57T | Unidirectional; lower PPPM (400 W); SMA (DO-214AC) package; no AEC-Q101 qualification. | Suitable only for DC-biased lines with defined polarity; not recommended for AC or floating interfaces. | Select when cost is critical and automotive qualification or bidirectional operation is unnecessary. |
| SMCJ6.0CAHE3/57T | Same bidirectional function and AEC-Q101 rating, but higher PPPM (3000 W); larger SMC (DO-214AB) package; 10.5 V VC @ 283 A. | Better suited for higher-energy surge environments (e.g., 12 V battery rail load dump), but requires more PCB area. | Choose when system-level surge tests exceed 1500 W or when design margin demands >2× peak power headroom. |
Compared with SMAJ6.0A-E3/57T and SMCJ6.0CAHE3/57T, the SMCG6.0CAHE3/57T delivers optimal balance of compact DO-215AB footprint, 1500 W surge capacity, and automotive qualification-making it ideal for space-constrained, high-reliability bidirectional protection where neither unidirectional nor oversized alternatives are acceptable.

FAQ
What is the clamping voltage of SMCG6.0CAHE3/57T under maximum surge conditions?
The SMCG6.0CAHE3/57T exhibits a maximum clamping voltage (VC) of 10.3 V when subjected to its rated peak pulse current (IPPM) of 145.6 A using the standardized 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and confirmed in the Vishay datasheet revision 09-Jan-2024, ensuring predictable overvoltage limiting for downstream ICs in the SMCG6.0CAHE3/57T's protection zone.
Is SMCG6.0CAHE3/57T suitable for automotive applications?
Yes, SMCG6.0CAHE3/57T is AEC-Q101 qualified and explicitly listed in Vishay's automotive-grade product documentation. Its construction-including glass-passivated junction, MSL Level 1 reflow compatibility, and -55 °C to +150 °C operating range-meets requirements for engine control, body electronics, and ADAS sensor interfaces. The SMCG6.0CAHE3/57T is referenced in Vishay's automotive application notes for CAN/LIN bus protection.
How does the bidirectional nature of SMCG6.0CAHE3/57T affect its placement in circuit design?
The SMCG6.0CAHE3/57T has no polarity marking and functions identically in both directions, allowing placement across any two nodes requiring symmetrical surge suppression-such as differential signal pairs, AC-coupled lines, or floating power rails. Unlike unidirectional TVS diodes, the SMCG6.0CAHE3/57T eliminates orientation errors during assembly and supports designs where voltage transients may reverse polarity.
What is the thermal resistance profile of SMCG6.0CAHE3/57T, and how does it impact PCB layout?
The SMCG6.0CAHE3/57T has a typical junction-to-lead thermal resistance (RθJL) of 15 °C/W and junction-to-ambient (RθJA) of 75 °C/W when mounted on 8.0 mm × 8.0 mm copper pads per terminal. To maintain reliability under repeated surges, PCB layout must replicate this pad area and avoid narrow traces; insufficient copper reduces power dissipation capability and risks thermal runaway in the SMCG6.0CAHE3/57T.
Does SMCG6.0CAHE3/57T meet industry safety standards for surge protection?
Yes, SMCG6.0CAHE3/57T carries Underwriters Laboratories recognition under UL 497B (file E136766) for protector classification, confirming compliance for telecom and industrial surge protection systems. It also meets IEC 61000-4-5 (surge immunity) and IEC 61000-4-2 (ESD) test levels when applied per Vishay's recommended layout guidelines-validating its role in certified end-equipment using the SMCG6.0CAHE3/57T.
