Product details
Overview
SMBG6.0A-E3/52 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 SMBG6.0A-E3/52 datasheet, SMBG6.0A-E3/52 pinout, SMBG6.0A-E3/52 application, or SMBG6.0A-E3/52 equivalent, key selection criteria include clamping performance under 10/1000 μs surge, junction temperature derating above 25 °C, unidirectional polarity with cathode band marking, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector, responding within picoseconds to transients exceeding its VWM threshold. Its glass-passivated junction ensures stable leakage (<800 μA at VWM) and low incremental surge resistance, enabling precise clamping during repetitive 0.01% duty-cycle surges.
The device is rated for TJ = −55 °C to +150 °C, with thermal resistance RθJA = 100 °C/W (on 0.2" × 0.2" pads) and RθJL = 20 °C/W, supporting high-reliability deployment in automotive powertrain and body electronics where thermal cycling and long-term stability are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum continuous reverse operating voltage before clamping begins; defines safe signal line operating margin. |
| VBR (min/max) | 6.67 V / 7.37 V at 10 mA - Confirmed breakdown range ensuring predictable turn-on across production lot. |
| VC @ IPPM | 10.3 V at 58.3 A - Clamping voltage under 600 W 10/1000 μs surge; limits downstream IC stress to safe levels. |
| IPPM | 58.3 A - Peak pulse current capability; determines survivability against ISO 7637-2 Pulse 1/2a/5a transients. |
| PPPM | 600 W - Peak pulse power rating; validates protection level for automotive load-dump and inductive switching events. |
| TJ max | +150 °C - Maximum junction temperature; enables operation in under-hood environments without thermal shutdown. |
| AEC-Q101 | Qualified - Certified for automotive applications per stress test requirements including HTOL, TC, and ESD. |
Pinout & Package
Package: SMBG (DO-215AA), surface-mount, low-profile gull-wing lead frame with matte tin-plated terminals solderable per J-STD-002 and JESD 22-B102. Cathode identified by molded band; polarity critical for unidirectional operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current sink during clamping | Connected to protected line (e.g., CAN_H); conducts surge current to ground when VLINE > VC. |
| Cathode | Reference terminal | Connected to system ground; cathode band marks this terminal; defines unidirectional conduction path. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 μs) | Enables single-device protection against severe automotive transients like ISO 16750-2 load dump without external series impedance. |
| Glass passivated chip junction | Ensures stable VBR tolerance and <800 μA leakage at VWM, critical for low-power sensor interfaces. |
| AEC-Q101 qualification | Validates reliability for automotive powertrain, ADAS, and body control modules requiring zero field failures. |
| MSL Level 1 (260 °C peak) | Supports standard lead-free reflow profiles without moisture-induced popcorn failure or delamination. |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (e.g., ESD), improving clamping accuracy for sub-5 V logic rails. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.0A-E3/52 | Same VWM/VBR/VC, but SMB (DO-214AA) package; 10% larger footprint and 10% higher RθJA. | Less suitable for ultra-dense automotive PCBs where SMBG's smaller DO-215AA saves 18% board area. | Select SMBG6.0A-E3/52 when space-constrained layouts or AEC-Q101 compliance are mandatory. |
| SMCJ6.0A-E3/52 | Higher PPPM = 1500 W, same VWM/VBR, but larger SMC (DO-214AB) package and 3× higher VC (13.4 V). | Used where higher energy absorption is needed (e.g., alternator output), but clamps less tightly on low-voltage rails. | Choose SMBG6.0A-E3/52 for precision clamping on 5 V/3.3 V systems where VC ≤10.3 V is required. |
Compared with SMBJ6.0A-E3/52 and SMCJ6.0A-E3/52, SMBG6.0A-E3/52 delivers optimal balance of compact size, tight clamping, and automotive qualification-making it preferred for CAN, LIN, and sensor nodes where board space and voltage margin are constrained.

FAQ
What is the clamping voltage of SMBG6.0A-E3/52 and how is it measured?
The SMBG6.0A-E3/52 has a maximum clamping voltage (VC) of 10.3 V at 58.3 A, measured under standardized 10/1000 μs unidirectional surge waveform per IEC 61000-4-5. This value reflects the actual voltage seen by downstream circuitry during worst-case transient events and is guaranteed across the full operating temperature range (−55 °C to +150 °C). The SMBG6.0A-E3/52 achieves this via low incremental resistance and optimized junction design.
Is SMBG6.0A-E3/52 suitable for bidirectional signal lines like RS-485 or USB?
No - SMBG6.0A-E3/52 is a unidirectional TVS diode, marked with a cathode band and intended only for DC-biased lines such as power rails or single-ended sensor outputs. For bidirectional data lines like RS-485 or USB, use the bidirectional variant SMBG6.0CA-E3/52, which provides symmetrical clamping in both polarities and no polarity marking. Using SMBG6.0A-E3/52 on AC-coupled signals risks forward conduction and failure.
Does SMBG6.0A-E3/52 require a series current-limiting resistor in typical applications?
No - the SMBG6.0A-E3/52 is designed for direct shunt protection without external series impedance. Its 600 W rating and low VC allow it to absorb full surge energy when mounted on recommended 5.0 mm × 5.0 mm copper pads. Adding a resistor would increase total clamping voltage (VC + IPPM × R) and reduce effective protection level. The SMBG6.0A-E3/52 datasheet specifies standalone operation per Fig. 1 and Fig. 3.
What is the meaning of the "E3/52" suffix in SMBG6.0A-E3/52?
The "E3" denotes RoHS-compliant, industrial-grade matte tin plating per JESD 201 Class 2 whisker resistance; "/52" indicates packaging in 7" diameter plastic tape and reel with 750 units per reel. This ordering code confirms compliance with environmental standards and defines logistics format - distinct from HE3 (AEC-Q101 qualified) or M3 (halogen-free) variants. The SMBG6.0A-E3/52 meets UL 497B recognition and flammability rating UL 94 V-0.
How does SMBG6.0A-E3/52 perform at elevated ambient temperatures?
The SMBG6.0A-E3/52 derates linearly above 25 °C per Fig. 2 in the datasheet: at 85 °C ambient, its 600 W peak pulse power drops to ~420 W, and IPPM reduces to ~41 A. This is due to junction temperature limits (TJ ≤ 150 °C) and thermal resistance RθJA = 100 °C/W. Proper PCB copper area and airflow must be maintained to sustain performance; the SMBG6.0A-E3/52 remains fully functional up to +150 °C junction temperature.
