Product details
Overview
SMCG6.0AHE3/9AT from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in the SMCG (DO-215AB) surface-mount package, designed for robust overvoltage protection of sensitive electronics. 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 (PPPM), clamping voltage of 10.3 V at 145.6 A IPPM (10/1000 µs), and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the SMCG6.0AHE3/9AT datasheet, SMCG6.0AHE3/9AT pinout, SMCG6.0AHE3/9AT application, or SMCG6.0AHE3/9AT equivalent, this device is selected for high-energy surge suppression in automotive power rails, industrial sensor interfaces, and DC-DC converter input stages where low clamping voltage, fast response (<1 ns), and stable junction temperature up to +150 °C are critical.
Technical Context
This TVS operates as a unidirectional avalanche diode with glass-passivated junction, optimized for clamping transients induced by inductive load switching or lightning surges on 5–12 V DC systems. Its low incremental surge resistance and 10.3 V clamping voltage at rated IPPM ensure minimal voltage overshoot during 145.6 A surge events.
The device uses the SMCG (DO-215AB) package with matte tin-plated leads, meets MSL Level 1 per J-STD-020, and supports reflow soldering at peak temperatures up to 260 °C. Polarity is marked by a cathode band; thermal resistance is 75 °C/W (junction-to-ambient) on standard 8.0 mm × 8.0 mm copper pads.
Key Specifications

IC Role / Device Role / Timing Role: Primary clamping device on VIN pin, coordinated with upstream fuse and downstream ceramic filtering. Use Value: 1500 W PPPM handles repetitive load-dump energy; low Rsurge ensures minimal voltage overshoot during fast 10/1000 µs pulses. |
Use Scenario: Overvoltage protection on VCC supply line of automotive CAN FD transceivers (e.g., TCAN1042-Q1) operating from 5–6 V rails. IC Role / Device Role / Timing Role: Unidirectional TVS placed between transceiver VCC and ground to prevent supply rail collapse during bus fault conditions. Use Value: Matches 6 V nominal supply with 6.0 V VWM and 10.3 V VC, ensuring transceiver remains powered and functional during 145.6 A surges. |
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 | Same VWM (6.0 V) and PPPM (400 W), but lower 400 W rating and SMA (DO-214AC) package; 12.3 V VC at 32.4 A IPPM. | Lower energy handling makes it suitable only for lighter-duty IEC 61000-4-2 ESD or low-energy inductive spikes-not full load-dump events. | Select SMAJ6.0A-E3/57T only if board space is constrained and surge threat level is limited to ±8 kV contact ESD or <100 A transients. |
| SMCJ6.0AHE3/9AT | Same VWM (6.0 V), higher PPPM (1500 W), identical SMCG package, but 10.5 V VC at 143 A IPPM-nearly identical clamping performance. | No functional difference in protection capability; SMCJ6.0AHE3/9AT is same family with identical electrical specs and AEC-Q101 qualification. | SMCJ6.0AHE3/9AT is a direct form-fit-function alternative with identical datasheet parameters and packaging; interchangeability confirmed by Vishay documentation. |

FAQ
What is the maximum clamping voltage of SMCG6.0AHE3/9AT under rated surge conditions?
The SMCG6.0AHE3/9AT has a maximum clamping voltage (VC) of 10.3 V when subjected to its rated peak pulse current (IPPM) of 145.6 A using the standard 10/1000 µs waveform. This value is measured per JEDEC test conditions and reflects actual voltage seen by protected circuitry during worst-case transient events, making it critical for validating safety margins of downstream 6 V ICs.
Is SMCG6.0AHE3/9AT suitable for bidirectional transient protection?
No, SMCG6.0AHE3/9AT is a unidirectional TVS diode, indicated by the "A" suffix (as opposed to "CA" for bidirectional variants like SMCG6.0CA). Its cathode band marks polarity, and it conducts only during reverse-biased overvoltage events. For bidirectional protection-such as AC signal lines or data buses-SMCG6.0CA or equivalent must be used instead.
Does SMCG6.0AHE3/9AT require derating at elevated ambient temperatures?
Yes, SMCG6.0AHE3/9AT must be derated above TA = 25 °C per Figure 2 in the Vishay datasheet (Document Number: 88457). Its peak pulse power (PPPM) decreases linearly with rising junction temperature, reaching ~750 W at TA = 85 °C when mounted on standard 8.0 mm × 8.0 mm copper pads-requiring thermal design validation for high-temperature automotive or industrial deployments.
What does the "HE3" suffix signify in SMCG6.0AHE3/9AT?
The "HE3" suffix in SMCG6.0AHE3/9AT indicates RoHS-compliant construction with AEC-Q101 qualification and matte tin plating meeting JESD 201 Class 2 whisker resistance. It distinguishes this variant from industrial-grade "E3" (RoHS, no AEC-Q101) and halogen-free "HM3" versions-ensuring suitability for automotive applications demanding both environmental compliance and stress-tested reliability.
Can SMCG6.0AHE3/9AT be used in place of SMAJ6.0A on the same PCB layout?
No, SMCG6.0AHE3/9AT cannot be used as a drop-in replacement for SMAJ6.0A due to differing packages: SMCG6.0AHE3/9AT uses DO-215AB (SMCG), while SMAJ6.0A uses DO-214AC (SMA). Their pad layouts, lead spacing, and thermal pad requirements are incompatible-PCB redesign is required to accommodate the larger SMCG footprint and different gull-wing lead geometry.
