Product details
Overview
SMCG5.0AHE3/57T from Vishay General Semiconductor is a unidirectional surface-mount TransZORB® transient voltage suppressor (TVS) diode in DO-215AB (SMCG) package, with 5.0 V stand-off voltage (VWM), 6.40–7.07 V breakdown voltage (VBR) at 10 mA, 1500 W peak pulse power (PPPM), and 163 A peak pulse current (IPPM) under 10/1000 µs waveform - designed for primary-level overvoltage protection of 5 V power rails and I/O lines in automotive ECUs and industrial sensors.
For engineers reviewing the SMCG5.0AHE3/57T datasheet, SMCG5.0AHE3/57T pinout, SMCG5.0AHE3/57T application, or SMCG5.0AHE3/57T equivalent, key selection criteria include AEC-Q101 qualification, low clamping voltage (9.20 V at IPPM), unidirectional polarity with cathode band marking, and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads.
Technical Context
This TVS diode operates as a clamping device in parallel with protected circuitry, triggering into avalanche conduction when reverse voltage exceeds VBR to limit transient energy. Its glass-passivated junction ensures stable leakage (<1000 µA at VWM) and fast response time (<1 ns), while the DO-215AB package provides low thermal resistance (RθJL = 15 °C/W) for reliable surge dissipation.
Rated for -55 °C to +150 °C junction temperature, SMCG5.0AHE3/57T meets J-STD-020 MSL Level 1 (260 °C peak reflow), supports 200 A non-repetitive forward surge (IFSM), and delivers 9.20 V clamping voltage at 163 A - enabling robust protection against ISO 7637-2 load dump and EFT bursts without crowbar action.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.0 V - maximum continuous reverse operating voltage before clamping begins; matches standard 5 V logic and supply rails. |
| VBR (min/max) | 6.40 V / 7.07 V at 10 mA - guaranteed avalanche initiation window; ensures consistent turn-on across production lots. |
| VC at IPPM | 9.20 V at 163 A - clamped voltage during 10/1000 µs surge; limits downstream stress to <9.2 V for 5 V systems. |
| PPPM | 1500 W - peak transient power handling capacity; sustains high-energy transients per ISO 16750-2 Pulse 5a. |
| TJ max. | +150 °C - maximum junction temperature; enables operation in under-hood automotive environments. |
| AEC-Q101 | Qualified - validated for automotive reliability including HTOL, TC, and UHAST; suitable for ASIL-B system nodes. |
| RθJL | 15 °C/W - junction-to-lead thermal resistance; allows effective heat transfer to PCB copper without external heatsink. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A-E3/57T | Same VWM (5.0 V), lower PPPM (400 W), SMA (DO-214AC) package, higher RθJA (110 °C/W). | Lower surge capacity; suited for consumer-grade 5 V ports where ISO 7637-2 compliance is not required. | Select SMAJ5.0A-E3/57T only if cost sensitivity outweighs automotive surge margin and thermal performance. |
| 1.5SMC5.0A | Same VWM (5.0 V), identical PPPM (1500 W), but larger SMC (DO-214AB) package (7.11 mm × 6.22 mm vs. SMCG's 7.11 mm × 5.59 mm) and no AEC-Q101 qualification. | Lacks automotive qualification; used in industrial power supplies where extended temperature range is less critical. | Choose 1.5SMC5.0A only when board space permits larger footprint and AEC-Q101 is not mandated. |
Compared with SMAJ5.0A-E3/57T and 1.5SMC5.0A, SMCG5.0AHE3/57T uniquely combines AEC-Q101 qualification, DO-215AB's compact gull-wing layout for fine-pitch routing, and 1500 W capability in a thermally optimized package - making it the only option qualified for under-hood 5 V rail protection requiring both high surge margin and automotive reliability.

FAQ
What is the clamping voltage of SMCG5.0AHE3/57T at its rated peak pulse current?
The SMCG5.0AHE3/57T has a maximum clamping voltage (VC) of 9.20 V at 163 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured per JEDEC test conditions and ensures that protected 5 V circuits remain below critical overvoltage thresholds during surge events. The SMCG5.0AHE3/57T maintains this clamping performance across its full operating temperature range (-55 °C to +150 °C).
Is SMCG5.0AHE3/57T suitable for automotive applications?
Yes, SMCG5.0AHE3/57T is AEC-Q101 qualified and specifically designed for automotive use, including body electronics, infotainment power rails, and sensor interface protection. Its construction features glass-passivated junctions, MSL Level 1 reflow compatibility, and validated performance across -55 °C to +150 °C. The SMCG5.0AHE3/57T meets requirements for ISO 7637-2 and ISO 16750-2 transient immunity testing in vehicle subsystems.
What does the 'HE3' suffix indicate in SMCG5.0AHE3/57T?
The 'HE3' suffix in SMCG5.0AHE3/57T denotes RoHS-compliant construction with AEC-Q101 qualification - distinguishing it from industrial-grade 'E3' variants. 'H' indicates AEC-Q101 qualification, 'E3' confirms RoHS compliance and matte tin plating. The '/57T' specifies packaging in 7-inch plastic tape-and-reel format with 850 units per reel. This suffix ensures traceability to automotive-grade process controls and reliability testing for SMCG5.0AHE3/57T.
How does the DO-215AB package of SMCG5.0AHE3/57T improve thermal performance compared to SMA (DO-214AC)?
The DO-215AB package of SMCG5.0AHE3/57T achieves a typical junction-to-lead thermal resistance (RθJL) of 15 °C/W - significantly lower than SMA's ~30–40 °C/W - due to wider gull-wing leads and optimized internal die attach. This enables more efficient heat transfer to PCB copper pads, supporting sustained 1500 W surge dissipation without thermal runaway. For SMCG5.0AHE3/57T, this translates to higher reliability in repeated surge scenarios and reduced derating above 25 °C ambient.
Can SMCG5.0AHE3/57T be used in bidirectional configurations?
No, SMCG5.0AHE3/57T is a unidirectional TVS diode, as indicated by the 'A' (not 'CA') suffix and cathode band marking. Bidirectional variants such as SMCG5.0CA exist in the same family but feature symmetric breakdown in both polarities and no polarity marking. Using SMCG5.0AHE3/57T in reverse-biased AC applications would result in forward conduction and potential failure. Always verify polarity alignment during layout for SMCG5.0AHE3/57T installation.
