Product details
Overview
SMBG6.0AHE3/5B from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMBG (DO-215AA) 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, 600 W peak pulse power (10/1000 µs), <10.3 V clamping voltage at 58.3 A peak current, and AEC-Q101 qualification for automotive use.
For engineers reviewing the SMBG6.0AHE3/5B datasheet, SMBG6.0AHE3/5B pinout, SMBG6.0AHE3/5B application, or SMBG6.0AHE3/5B equivalent, key selection criteria include clamping performance under 10/1000 µs surge, unidirectional polarity with cathode band marking, RoHS-compliant matte tin terminals, MSL Level 1 reflow compatibility, and junction temperature range of –55 °C to +150 °C.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds VBR, it avalanches to divert transient energy away from downstream circuitry. Its glass-passivated junction ensures stable breakdown and low leakage (<800 µA at VWM), while the low incremental surge resistance enables tight clamping during fast transients.
The device is rated for 100 A non-repetitive forward surge (8.3 ms half-sine) and exhibits typical thermal resistance of 100 °C/W (junction-to-ambient) on 5.0 mm × 5.0 mm copper pads. It meets UL 497B recognition (QVGQ2) and complies with ANSI/IEEE C62.35 surge standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum continuous reverse operating voltage before clamping begins; sets system-level signal integrity margin. |
| VBR @ IT = 10 mA | 6.67–7.37 V - Verified avalanche onset range; ensures predictable turn-on without premature conduction. |
| VC @ IPPM = 58.3 A | ≤10.3 V - Clamped voltage during 600 W 10/1000 µs surge; protects 5 V logic rails and MOSFET gate drivers. |
| IPPM | 58.3 A - Peak surge current capability; supports IEC 61000-4-5 Level 4 (4 kV) compliance with proper PCB layout. |
| TJ Range | –55 °C to +150 °C - Full automotive-grade operating envelope; validated per AEC-Q101 stress test conditions. |
| Package | SMBG (DO-215AA) - Surface-mount gull-wing footprint; compatible with automated SMT placement and J-STD-020 reflow profiles. |
| Leakage @ VWM | ≤800 µA - Low standby current; avoids loading of high-impedance sensor bias networks or reference lines. |
Pinout & Package
Package: SMBG (DO-215AA), gull-wing surface-mount case with molded UL 94 V-0 compound and matte tin-plated leads. Cathode identified by band marking on anode-end side of body.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.0A-E3/5B | Same VWM (6.0 V) and VC (10.3 V), but lower PPPM (600 W vs. SMBJ's 600 W - identical rating); differs in package outline (SMB vs. SMBG) and thermal resistance (RθJA = 110 °C/W vs. 100 °C/W). | Less optimized for high-reliability automotive due to lack of AEC-Q101 qualification; suitable for industrial/commercial only. | Select SMBG6.0AHE3/5B when AEC-Q101 validation, tighter thermal performance, or DO-215AA mechanical fit is required. |
| 1.5SMC6.0A | Same electrical specs (VWM = 6.0 V, VC = 10.3 V, PPPM = 600 W), but larger SMC (DO-214AB) package; higher RθJA (125 °C/W) and different mounting pad layout. | Used where board space allows larger footprint and higher surge margin is needed via external heatsinking. | Choose SMBG6.0AHE3/5B for space-constrained designs requiring gull-wing SMT compatibility and automotive qualification. |
Compared with SMBJ6.0A-E3/5B and 1.5SMC6.0A, SMBG6.0AHE3/5B delivers superior thermal performance (100 °C/W), AEC-Q101 validation, and DO-215AA gull-wing geometry-making it optimal for automotive modules, compact industrial sensors, and certified telecom interfaces where reliability and footprint are critical.

FAQ
What is the maximum clamping voltage of SMBG6.0AHE3/5B at its rated peak pulse current?
The SMBG6.0AHE3/5B has a maximum clamping voltage (VC) of 10.3 V when subjected to its rated peak pulse current (IPPM) of 58.3 A under the standard 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and verified at TA = 25 °C on the recommended 5.0 mm × 5.0 mm copper pad layout. The SMBG6.0AHE3/5B maintains this clamping performance across its full operating temperature range.
Is SMBG6.0AHE3/5B suitable for automotive applications?
Yes, SMBG6.0AHE3/5B is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood and infotainment systems. Its construction includes glass-passivated junctions, matte tin-plated leads compliant with J-STD-002, and MSL Level 1 reflow capability up to 260 °C. The SMBG6.0AHE3/5B also carries UL 497B recognition (QVGQ2), supporting system-level safety certification in automotive electronics.
What does the "HE3" suffix indicate in SMBG6.0AHE3/5B?
The "HE3" suffix in SMBG6.0AHE3/5B denotes RoHS-compliant construction with AEC-Q101 qualification. Per Vishay's ordering nomenclature, "HE3" identifies the base part as industrial-grade, halogen-free, RoHS-compliant, and AEC-Q101-qualified-distinguishing it from "E3" (RoHS, non-AEC-Q101) and "HM3" (halogen-free, RoHS, AEC-Q101). The "5B" indicates 13-inch tape-and-reel packaging with 3200 units per reel.
How does SMBG6.0AHE3/5B differ from SMBG6.0CA?
SMBG6.0AHE3/5B is unidirectional, with cathode marked by a band and intended for DC line protection (e.g., 12 V power rails), whereas SMBG6.0CA is bidirectional and used for AC-coupled or symmetrical signal lines (e.g., RS-485, CAN). Their breakdown voltages differ: SMBG6.0AHE3/5B has VBR = 6.67–7.37 V (unidirectional), while SMBG6.0CA has symmetric VBR = 6.67–7.37 V in both directions. The SMBG6.0AHE3/5B is not interchangeable with SMBG6.0CA without circuit redesign.
What is the thermal resistance of SMBG6.0AHE3/5B, and how does it affect layout?
The SMBG6.0AHE3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value assumes no internal layer copper; adding inner-layer thermal vias reduces effective RθJA. Layout must provide adequate copper area and thermal relief to maintain TJ ≤ 150 °C during repetitive surge events. The SMBG6.0AHE3/5B's low RθJA supports higher duty-cycle operation than comparable SMC-packaged devices.
