Product details
Overview
SMBG64A-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 DC power rails and signal lines. It features a 64 V stand-off voltage (VWM), 71.1–78.6 V breakdown voltage (VBR) at 1 mA, 103 V maximum clamping voltage (VC) at 5.8 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform.
For engineers reviewing the SMBG64A-E3/52 datasheet, SMBG64A-E3/52 pinout, SMBG64A-E3/52 application, or SMBG64A-E3/52 equivalent, key selection criteria include clamping performance under 5.8 A surge, unidirectional polarity with cathode band marking, AEC-Q101 qualification for automotive use, 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 (<1.0 μA at 64 V) and repeatable breakdown behavior across temperature (−55 °C to +150 °C).
The device delivers 600 W peak pulse power handling per 10/1000 μs waveform at 25 °C, derating linearly above TA = 25 °C with RθJA = 100 °C/W. It supports unidirectional surge suppression only, with cathode identification via molded band and no bidirectional capability.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |

FAQ
What is the clamping voltage of SMBG64A-E3/52 at its rated peak pulse current?
The SMBG64A-E3/52 has a maximum clamping voltage (VC) of 103 V at 5.8 A peak pulse current (IPPM) under a 10/1000 μs waveform. This value is measured per standard test conditions and defines the upper voltage limit imposed on protected circuitry during surge events. The SMBG64A-E3/52 maintains this clamping performance across its specified operating temperature range.
Is SMBG64A-E3/52 suitable for automotive applications?
Yes, SMBG64A-E3/52 is AEC-Q101 qualified and explicitly rated for automotive use. Its construction-including glass-passivated junction, MSL Level 1 rating, and operation from −55 °C to +150 °C-meets stringent automotive reliability requirements. The SMBG64A-E3/52 is commonly deployed in engine control modules, body electronics, and ADAS power rails where transient immunity is critical.
Does SMBG64A-E3/52 support bidirectional transient suppression?
No, SMBG64A-E3/52 is a unidirectional TVS diode. Its polarity is defined by a cathode band marking, and it conducts only during reverse-bias overvoltage events. For bidirectional protection, Vishay offers the SMBG64CA variant. The SMBG64A-E3/52 must be oriented with cathode toward the protected line's higher-potential side to function correctly.
What is the maximum steady-state reverse leakage current for SMBG64A-E3/52?
The SMBG64A-E3/52 exhibits a maximum reverse leakage current (ID) of 1.0 μA at its rated stand-off voltage (VWM) of 64 V and ambient temperature of 25 °C. This low leakage ensures minimal power loss and avoids interference with high-impedance sensing circuits. Leakage remains within specification across the full operating temperature range.
What packaging and reel configuration is supplied for SMBG64A-E3/52?
SMBG64A-E3/52 is supplied in 7-inch plastic tape and reel format with a base quantity of 750 units per reel (package code "52"). The device uses gull-wing leads compatible with standard SMT reflow profiles, and the E3 suffix indicates RoHS-compliant, industrial-grade construction with matte tin plating per J-STD-002.
