Product details
Overview
SMBG6.0A-E3/5B 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), clamping voltage of 10.3 V at 58.3 A, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the SMBG6.0A-E3/5B datasheet, SMBG6.0A-E3/5B pinout, SMBG6.0A-E3/5B application, or SMBG6.0A-E3/5B equivalent, key selection criteria include clamping performance under 10/1000 µs surge, junction temperature derating above 25 °C, unidirectional polarity marking (cathode band), and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a clamping device that transitions from high-impedance to low-impedance state within picoseconds upon detecting a transient exceeding its breakdown threshold. Its glass-passivated junction ensures stable VBR tolerance (±5 %) and low leakage (<800 µA at VWM), while the SMBG package provides MSL Level 1 moisture sensitivity and 260 °C lead-free reflow compatibility.
The device delivers 600 W peak pulse power handling per JEDEC-standard 10/1000 µs waveform at TA = 25 °C, with thermal resistance RθJA = 100 °C/W and RθJL = 20 °C/W. It supports repetitive surges at 0.01 % duty cycle and withstands 100 A non-repetitive forward surge (8.3 ms half-sine) - critical for protecting MOSFET gates and IC power rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - maximum continuous reverse operating voltage before clamping begins; sets safe margin below system supply rail |
| VBR @ IT = 10 mA | 6.67–7.37 V - verified breakdown range ensuring reliable turn-on during transients without premature conduction |
| VC @ IPPM = 58.3 A | 10.3 V - clamped voltage during full-rated 600 W surge; defines maximum stress imposed on protected circuit |
| PPPM | 600 W - peak pulse power rating per 10/1000 µs waveform; determines survivability against lightning-induced or ESD-like events |
| IFSM | 100 A - single 8.3 ms half-sine forward surge current rating; validates robustness against inductive kickback in power switching circuits |
| TJ max. | +150 °C - maximum junction temperature; enables operation in under-hood automotive environments with thermal derating |
| Package | SMBG (DO-215AA) - surface-mount gull-wing package with 0.235–0.255 inch body length; optimized for automated pick-and-place and reflow |
Pinout & Package
SMBG6.0A-E3/5B uses the SMBG (DO-215AA) package: a compact, low-profile gull-wing surface-mount outline with cathode band marking on the anode-side terminal. Dimensions are 6.48 mm × 3.94 mm × 2.41 mm (L × W × H), compliant with UL 94 V-0 flammability rating and J-STD-020 MSL Level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (marked end) | Transient current sink | Connected to protected line; conducts surge current to ground when VLINE > VBR; polarity must match PCB silkscreen |
| Anode | Reference node | Typically tied to system ground or lowest potential reference; completes clamping path during overvoltage event |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 µs) | Enables protection against IEC 61000-4-5 Level 4 surges (4 kV line-to-ground) without degradation |
| AEC-Q101 qualified | Validated for automotive applications including engine control units, ADAS sensors, and infotainment power supplies |
| Glass passivated junction | Ensures long-term stability of VBR and leakage current across temperature and humidity stress conditions |

IC Role / Device Role / Timing Role: Low-capacitance TVS mounted directly at connector entry point to shunt ESD and cable discharge events. Use Value: Sub-100 ps response time and <800 µA leakage at 6.0 V preserve signal integrity and measurement accuracy. |

IC Role / Device Role / Timing Role: Standoff-rated TVS placed upstream of USB power delivery controller to absorb hot-plug and contact bounce transients. Use Value: 6.0 V VWM allows compatibility with 5 V ±5 % USB spec while clamping to 10.3 V - well below 20 V PD fault thresholds. | Use Scenario: Protecting Ethernet PHY interface lines (e.g., MDI-X) from induced surges in outdoor telecom cabinets. IC Role / Device Role / Timing Role: Unidirectional TVS used in conjunction with common-mode chokes to suppress differential-mode surges on twisted-pair lines. Use Value: 600 W rating meets GR-1089-CORE Level 3 requirements for telecom central office equipment. |
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 | Same VWM (6.0 V), identical SMB package, but rated for 600 W with lower clamping voltage (10.0 V @ 60 A); slightly tighter VBR tolerance (6.67–7.22 V) | Preferred where lower clamping voltage is required to protect 5 V logic with tighter margins | Select SMBJ6.0A if system-level testing shows 0.3 V lower clamping improves margin against IC absolute maximum ratings |
| SMAJ6.0A | Same electrical specs but in smaller SMA (DO-214AC) package; lower thermal mass and higher RθJA (150 °C/W); not AEC-Q101 qualified | Suitable for cost-sensitive consumer applications where automotive qualification is unnecessary | Choose SMAJ6.0A only for non-automotive designs with adequate board-level thermal relief and no AEC compliance requirement |
Compared with SMBG6.0A-E3/5B, SMBJ6.0A offers marginally better clamping but identical footprint and qualification, whereas SMAJ6.0A trades automotive reliability and thermal robustness for size and cost - making SMBG6.0A-E3/5B optimal for space-constrained, high-reliability automotive and industrial deployments.

FAQ
What is the maximum clamping voltage of SMBG6.0A-E3/5B under full-rated surge conditions?
The SMBG6.0A-E3/5B exhibits a maximum clamping voltage (VC) of 10.3 V when subjected to its rated peak pulse current of 58.3 A (corresponding to 600 W at 10/1000 µs). This value is measured per JEDEC standards with the device mounted on 0.2" × 0.2" copper pads and represents the upper limit of voltage imposed on the protected circuit during worst-case transient events.
Is SMBG6.0A-E3/5B suitable for bidirectional transient protection?
No, SMBG6.0A-E3/5B is a unidirectional TVS diode, indicated by the "A" suffix and cathode band marking. For bidirectional protection, Vishay offers the SMBG6.0CA variant (with "CA" suffix), which provides symmetrical clamping in both polarities and no polarity marking. Using SMBG6.0A-E3/5B for AC or bipolar signals risks forward conduction and failure.
Does SMBG6.0A-E3/5B require derating at elevated ambient temperatures?
Yes, SMBG6.0A-E3/5B must be derated above TA = 25 °C per Figure 2 in the datasheet. Its peak pulse power capability decreases linearly to zero at +150 °C junction temperature. At 85 °C ambient with typical PCB layout, usable PPPM drops to approximately 420 W - design validation must include thermal simulation or empirical testing under worst-case operating conditions.
What does the "E3/5B" suffix indicate in SMBG6.0A-E3/5B?
The "E3" denotes RoHS-compliant, industrial-grade matte tin plating meeting JESD 201 Class 2 whisker resistance, while "5B" specifies packaging in 13-inch diameter tape-and-reel format containing 3200 units. This differs from "52" (7-inch reel, 750 units) and confirms compliance with lead-free assembly standards and high-volume SMT logistics requirements.
Can SMBG6.0A-E3/5B replace SMBJ6.0A in an existing design without layout changes?
Yes - SMBG6.0A-E3/5B and SMBJ6.0A share identical SMB (DO-215AA) package dimensions, pinout, and mounting pad layout. However, SMBG6.0A-E3/5B has a slightly higher clamping voltage (10.3 V vs. 10.0 V) and broader VBR range; functional equivalence requires verification that the 0.3 V difference does not violate downstream IC voltage tolerances in the target application.
