Product details
Overview
SMBG6.0HE3/52 from Vishay General Semiconductor is a uni-directional transient voltage suppressor (TVS) diode in DO-215AA (SMBG) package, designed for clamping inductive switching transients and ESD events on power and signal lines. It features 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 IPPM, and AEC-Q101 qualification for automotive electronics protection.
For engineers reviewing the SMBG6.0HE3/52 datasheet, SMBG6.0HE3/52 pinout, SMBG6.0HE3/52 application, or SMBG6.0HE3/52 equivalent, key selection criteria include unidirectional polarity, 600 W surge capability, 10.3 V max clamping at rated current, RoHS-compliant AEC-Q101 qualification, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a voltage-clamping protection device in series with sensitive downstream circuitry-typically placed between power rail and ground or across signal line and reference. Its glass-passivated junction ensures stable avalanche behavior under repetitive 10/1000 µs surges at 0.01% duty cycle, with thermal resistance RθJA = 100 °C/W and RθJL = 20 °C/W enabling reliable operation up to TJ = 150 °C.
The SMBG6.0HE3/52 exhibits low incremental surge resistance and fast response time (<1 ns), delivering consistent clamping performance across -55 °C to +150 °C ambient. Its matte tin-plated leads meet J-STD-002 and JESD 22-B102 solderability standards, and the HE3 suffix confirms compliance with JESD 201 Class 2 whisker testing and AEC-Q101 stress requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum continuous reverse operating voltage before conduction begins; defines safe operating margin below breakdown. |
| VBR (min/max) | 6.67 V / 7.37 V at IT = 10 mA - Confirmed avalanche onset range; ensures predictable turn-on during transients. |
| VC @ IPPM | 10.3 V at 58.3 A - Clamped voltage during 600 W 10/1000 µs surge; limits stress on protected ICs or MOSFETs. |
| PPPM | 600 W - Peak pulse power handling per single 10/1000 µs waveform; supports robust protection in automotive load-dump scenarios. |
| ID @ VWM | 800 µA - Reverse leakage at 6.0 V; low enough to avoid system power loss or false triggering in battery-powered circuits. |
| TJ max | +150 °C - Maximum junction temperature; enables use in under-hood automotive environments and industrial enclosures. |
| Package | DO-215AA (SMBG) - Surface-mount package with gull-wing leads; compatible with standard reflow profiles and automated pick-and-place. |
Pinout & Package
DO-215AA (SMBG) package: low-profile surface-mount outline with gull-wing terminals, 0.235–0.255 inch body length, cathode band marking on anode-side end. Mounting requires 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal for rated power dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Current entry point in forward bias; connected to protected line (e.g., VCC or signal) | Terminal where transient energy enters during clamping; must be routed with minimal inductance to preserve response speed. |
| Cathode (banded end) | Current exit point in forward bias; connected to ground or return path | Reference node for clamping action; requires low-impedance connection to system ground plane to maintain VC specification. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and surge endurance-enables use in ADAS, body control, and powertrain modules. |
| 600 W peak pulse power (10/1000 µs) | Withstands high-energy transients such as ISO 7637-2 Pulse 5a (load dump) without degradation when mounted per recommended pad layout. |
| Glass passivated junction | Ensures stable, repeatable avalanche characteristics over lifetime and temperature; eliminates parameter drift due to moisture or contamination. |
| MSL Level 1 (260 °C peak) | Compatible with standard lead-free reflow profiles without preconditioning; eliminates moisture-related popcorning during assembly. |
| RoHS-compliant HE3 suffix | Meets JESD 201 Class 2 whisker resistance and UL 94 V-0 flammability-supports safety-critical and export-controlled designs. |

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), same DO-214AA (SMB) package but slightly larger footprint; 600 W rating, 10.3 V VC, but not AEC-Q101 qualified. | Approved for commercial/industrial use only; unsuitable for automotive OEM or Tier-1 production without additional qualification. | Select SMBJ6.0A-E3/52 only if AEC-Q101 is not required and PCB layout accommodates larger SMB vs. SMBG outline. |
| SMAJ6.0AHE3/A | Same VWM and AEC-Q101 qualification, but lower 400 W PPPM rating and higher 10.5 V VC at 38.9 A; uses smaller DO-214AC (SMA) package. | Limited to lower-energy transients (e.g., IEC 61000-4-5 Level 3); insufficient for ISO 7637-2 Pulse 5a load-dump protection. | Choose SMAJ6.0AHE3/A only for space-constrained consumer or non-automotive applications where 400 W suffices. |
Compared with SMBJ6.0A-E3/52 and SMAJ6.0AHE3/A, the SMBG6.0HE3/52 uniquely combines AEC-Q101 qualification, 600 W surge capacity, and compact DO-215AA packaging-making it the only option among the three validated for automotive front-end power rail protection without layout or reliability compromise.

FAQ
What is the polarity configuration of SMBG6.0HE3/52?
The SMBG6.0HE3/52 is a uni-directional transient voltage suppressor diode. Its cathode is marked by a band on one end of the DO-215AA package, and it conducts only when the anode is more positive than the cathode by ≥6.67 V. This configuration makes it suitable for DC power rail protection where reverse voltage blocking is required.
Does SMBG6.0HE3/52 meet automotive qualification standards?
Yes, SMBG6.0HE3/52 is AEC-Q101 qualified, as confirmed by Vishay's documentation (Document Number 88456, Revision 12-Nov-12). The HE3 suffix explicitly denotes AEC-Q101 compliance, including stress testing for temperature cycling, high-temperature reverse bias, and surge endurance-making SMBG6.0HE3/52 appropriate for automotive front-end, body control, and ADAS modules.
What is the maximum clamping voltage for SMBG6.0HE3/52 under rated surge conditions?
The SMBG6.0HE3/52 has a maximum clamping voltage (VC) of 10.3 V at its rated peak pulse current (IPPM) of 58.3 A, measured using the standardized 10/1000 µs waveform. This value is guaranteed across the full operating temperature range and forms the basis for downstream IC overvoltage margin analysis in designs using SMBG6.0HE3/52.
Can SMBG6.0HE3/52 be used in bi-directional protection circuits?
No, SMBG6.0HE3/52 is strictly uni-directional. Bi-directional variants in the same SMBG family carry a "CA" suffix (e.g., SMBG6.0CA). Using SMBG6.0HE3/52 in AC or bidirectional signal paths would result in forward conduction during negative half-cycles, causing malfunction or damage. Always select CA-suffixed parts for symmetrical transient suppression.
What is the thermal resistance profile of SMBG6.0HE3/52, and how does it affect PCB layout?
SMBG6.0HE3/52 has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W and junction-to-lead (RθJL) of 20 °C/W. To achieve rated 600 W pulse power, Vishay specifies mounting on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. Reducing pad area or omitting thermal vias increases junction temperature and de-rates surge capability-so PCB layout must follow the documented pad dimensions for full specification compliance.
