Product details
Overview
SMBG6.0AHE3/52 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), clamping voltage of 10.3 V at 58.3 A, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the SMBG6.0AHE3/52 datasheet, SMBG6.0AHE3/52 pinout, SMBG6.0AHE3/52 application, or SMBG6.0AHE3/52 equivalent, key selection criteria include unidirectional polarity, 100 A IFSM surge rating, low 100 °C/W junction-to-ambient thermal resistance, RoHS-compliant HE3 suffix with AEC-Q101 qualification, and compatibility with automated SMT placement on standard 0.2" × 0.2" copper pads.
Technical Context
This TVS diode operates as a clamping device in parallel with protected circuitry, activating when transient voltage exceeds its breakdown threshold to divert surge current away from downstream components. Its glass-passivated junction ensures stable leakage performance and fast response time (<1 ns), while the low incremental surge resistance minimizes clamping voltage overshoot during high-current transients.
The SMBG6.0AHE3/52 is rated for -55 °C to +150 °C operating junction temperature, meets MSL Level 1 per J-STD-020 (peak reflow 260 °C), and delivers 600 W peak pulse power under repetitive 0.01% duty cycle conditions - enabling reliable protection against inductive switching spikes and ESD events in harsh environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum continuous reverse operating voltage before clamping begins; sets system-level DC bias margin. |
| VBR (min/max) | 6.67 V / 7.37 V at 10 mA - Confirmed breakdown range ensures predictable turn-on across production lot and temperature. |
| VC @ IPPM | 10.3 V at 58.3 A - Clamping voltage under full 600 W surge defines worst-case voltage stress on protected IC or MOSFET. |
| PPPM | 600 W (10/1000 μs waveform) - Peak transient energy handling capacity determines suitability for automotive load-dump or industrial switching surges. |
| IFSM | 100 A (8.3 ms half-sine) - Forward surge rating validates robustness against repeated inrush or fault currents in power rail protection. |
| TJ max | +150 °C - Maximum junction temperature enables operation in under-hood automotive or high-ambient industrial enclosures. |
| Package | SMBG (DO-215AA) - Surface-mount outline with 0.235" × 0.255" footprint and gull-wing leads compatible with IPC-7351B land patterns. |

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-E3/52 | Same VWM (6.0 V), but lower PPPM = 600 W (same rating), higher VC = 10.5 V at 58.1 A; SMBJ package has larger footprint (0.265" × 0.235") and higher RθJA (110 °C/W). | Less suitable for space-constrained automotive modules; identical surge capability but slightly higher clamping voltage increases risk of marginal IC stress. | Select SMBG6.0AHE3/52 when board area is limited or thermal performance below 100 °C/W is required. |
| 1.5SMC6.0A | Same VWM/VBR specs, but DO-214AB package (larger), PPPM = 1500 W, VC = 10.3 V at 146 A; not AEC-Q101 qualified; higher IFSM = 200 A. | Targeted at industrial power supplies rather than automotive; lacks automotive qualification and has longer lead time due to non-automotive grade screening. | Choose SMBG6.0AHE3/52 for AEC-Q101 compliance and surface-mount compatibility in automotive ECUs; use 1.5SMC6.0A only where higher surge margin justifies larger footprint and non-automotive qualification. |
Compared with SMBJ6.0A-E3/52 and 1.5SMC6.0A, SMBG6.0AHE3/52 uniquely combines AEC-Q101 qualification, SMBG's compact footprint, and 100 °C/W thermal resistance - making it optimal for automotive and space-sensitive industrial designs requiring validated reliability and efficient heat dissipation.

FAQ
What is the clamping voltage of SMBG6.0AHE3/52 at its rated peak pulse current?
The SMBG6.0AHE3/52 has a maximum clamping voltage (VC) of 10.3 V at its rated peak pulse current (IPPM) of 58.3 A, measured under the standardized 10/1000 μs double-exponential waveform. This value defines the upper voltage limit imposed on protected circuitry during a full 600 W transient event and is confirmed in the Vishay datasheet revision 09-Jan-2024, page 2.
Is SMBG6.0AHE3/52 qualified for automotive applications?
Yes, SMBG6.0AHE3/52 is explicitly AEC-Q101 qualified, as indicated by the "HE3" suffix in its part number and confirmed in the Vishay datasheet section "MECHANICAL DATA". This qualification covers stress testing for temperature cycling, humidity, mechanical shock, and high-temperature operating life - validating its use in engine control units, body electronics, and ADAS sensor modules.
What does the "HE3" suffix mean in SMBG6.0AHE3/52?
The "HE3" suffix in SMBG6.0AHE3/52 denotes RoHS-compliant construction with AEC-Q101 qualification and matte tin-plated gull-wing leads meeting J-STD-002 and JESD 22-B102 solderability standards. It distinguishes this variant from industrial-grade "E3" or halogen-free "HM3" versions, confirming automotive-grade reliability and process control.
Can SMBG6.0AHE3/52 be used in bidirectional protection circuits?
No, SMBG6.0AHE3/52 is a unidirectional TVS diode, as indicated by the "A" (not "CA") suffix and presence of cathode band marking. For bidirectional operation, Vishay specifies parts with "CA" suffix (e.g., SMBG6.0CA). Using SMBG6.0AHE3/52 in AC-coupled or symmetrical signal lines would result in forward conduction during negative transients and potential failure.
What is the maximum operating temperature for SMBG6.0AHE3/52?
The SMBG6.0AHE3/52 has a specified operating junction temperature range of -55 °C to +150 °C, with thermal resistance RθJA = 100 °C/W under standard 0.2" × 0.2" copper pad layout. This enables reliable operation in under-hood automotive environments and high-ambient industrial settings without derating below full 600 W pulse rating until TA exceeds 25 °C.
