Product details
Overview
SMBG60A-E3/52 from Vishay General Semiconductor is a unidirectional surface-mount TransZORB® transient voltage suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a 60 V stand-off voltage (VWM), 66.7–73.7 V breakdown voltage (VBR) at 1 mA, 600 W peak pulse power (10/1000 μs), 96.8 V maximum clamping voltage (VC) at 6.2 A, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the SMBG60A-E3/52 datasheet, SMBG60A-E3/52 pinout, SMBG60A-E3/52 application, or SMBG60A-E3/52 equivalent, key selection criteria include clamping performance under 10/1000 μs surge, unidirectional polarity with cathode band marking, DO-215AA (SMBG) package thermal resistance (RθJA = 100 °C/W), and compliance with UL 497B and JESD22-B102 solderability standards.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds VBR, it avalanches to divert surge current away from downstream circuitry. Its glass-passivated junction ensures stable leakage (<1.0 μA at VWM) and fast response time (<1 ns), critical for protecting MOSFET gates and microcontroller I/O against ESD and inductive switching transients.
The SMBG60A-E3/52 is rated for 100 A non-repetitive forward surge (8.3 ms half-sine) and 6.2 A peak pulse current (IPPM) under 10/1000 μs waveform, with thermal derating above 25 °C per Fig. 2. Its MSL Level 1 rating (260 °C peak reflow) and matte tin-plated leads support automated SMT assembly without whisker risk.
Key Specifications
| Parameter | Value and Actual 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 |
|---|---|---|---|
| SMBJ60A-E3/52 | Same VWM/VBR/VC, but lower PPPM = 600 W (same rating) and higher IPPM = 6.5 A; identical SMB (DO-214AA) package footprint but 0.004" thinner profile | Preferred where board height is constrained (<1.7 mm vs. 2.1 mm); same thermal derating curve but slightly lower RθJA (85 °C/W) | Select SMBJ60A-E3/52 for space-constrained layouts; verify pad thermal relief matches SMBG's larger copper requirement. |
| SMCJ60A-E3/52 | Same electrical specs but in larger SMC (DO-214AB) package; PPPM = 1500 W, IPPM = 15.4 A, RθJA = 40 °C/W | Used in high-energy surge zones (e.g., AC/DC front-end, PoE injectors); requires 3× PCB area and different stencil design | Choose SMCJ60A-E3/52 only when >600 W surge margin is required; avoid if layout cannot accommodate 7.11 mm × 6.22 mm footprint. |

FAQ
What is the maximum clamping voltage of SMBG60A-E3/52 under a 10/1000 μs surge?
The SMBG60A-E3/52 has a maximum clamping voltage (VC) of 96.8 V at 6.2 A peak pulse current (IPPM) under the standardized 10/1000 μs waveform. This value is measured per Figure 1 in Vishay document 88456 and defines the upper voltage limit imposed on protected circuitry during surge events. Designers use this parameter to verify that downstream components remain within their absolute maximum ratings.
Is SMBG60A-E3/52 suitable for automotive applications?
Yes, SMBG60A-E3/52 is AEC-Q101 qualified per Vishay documentation, confirming its suitability for automotive applications such as engine control units, body control modules, and ADAS sensor interfaces. Its operating junction temperature range of –55 °C to +150 °C, MSL Level 1 reflow compatibility, and UL 497B recognition further validate its use in harsh automotive environments.
What does the "E3/52" suffix indicate in SMBG60A-E3/52?
The "E3" suffix denotes RoHS-compliant, industrial-grade construction with matte tin-plated leads meeting J-STD-002 and JESD 22-B102 solderability standards. The "/52" indicates packaging in 7" diameter plastic tape and reel with a base quantity of 750 units-standard for automated SMT placement. This ordering code ensures traceable, whisker-tested, and lead-free compliant supply.
How does SMBG60A-E3/52 differ from bidirectional TVS diodes like SMBG60CA?
SMBG60A-E3/52 is unidirectional and features a cathode band for polarity identification, enabling asymmetric clamping from anode to cathode only. In contrast, SMBG60CA provides symmetrical clamping in both directions with no polarity marking. The SMBG60A-E3/52 is selected for DC power line protection where reverse conduction must be blocked, whereas SMBG60CA suits AC-coupled signal lines or differential buses.
What is the thermal resistance of SMBG60A-E3/52, and how does it affect layout?
The SMBG60A-E3/52 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 requires designers to allocate sufficient copper area and consider thermal vias to maintain TJ ≤ 150 °C under repeated surges. Reducing pad size increases RθJA, risking premature thermal runaway during high-duty-cycle transients.
