Product details
Overview
SMBG13A-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 13 V stand-off voltage (VWM), 14.4–15.9 V breakdown voltage (VBR) at 1 mA, 21.5 V maximum clamping voltage (VC) at 27.9 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - deployed on power rails and signal lines in automotive ECUs and industrial sensor interfaces.
For engineers reviewing the SMBG13A-E3/52 datasheet, SMBG13A-E3/52 pinout, SMBG13A-E3/52 application, or SMBG13A-E3/52 equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), junction temperature range (–55 to +150 °C), and bidirectional/unidirectional polarity distinctions critical for ESD and surge design validation.
Technical Context
The SMBG13A-E3/52 operates as a silicon avalanche diode with glass-passivated junction, enabling fast response (<1 ns) to transients and low incremental surge resistance. Its unidirectional configuration uses cathode-band marking and exhibits forward conduction only during reverse overvoltage events - not intended for DC blocking or rectification.
It is rated for 100 A non-repetitive forward surge current (IFSM, 8.3 ms half-sine), derated above 25 °C per Fig. 2, and meets J-STD-020 MSL Level 1 (260 °C peak reflow). The device is AEC-Q101 qualified and UL 497B recognized (QVGQ2, E136766).

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13A-E3/52 | Same VWM/VBR/VC, but lower PPPM = 600 W (same rating), different package: SMB (DO-214AA), slightly larger footprint (4.58 mm × 3.94 mm vs. SMBG's 4.57 mm × 3.94 mm) | SMBJ13A-E3/52 has higher RθJA (110 °C/W) and no AEC-Q101 qualification - suitable for commercial, not automotive, use | Select SMBG13A-E3/52 when AEC-Q101 compliance, tighter thermal performance (RθJA = 100 °C/W), or DO-215AA space constraints apply |
| 1.5SMC13A | Same electrical specs (VWM = 13 V, VC = 21.5 V), but SMC (DO-214AB) package - larger body (7.11 mm × 6.22 mm), higher IPPM (32.3 A), same PPPM = 600 W | 1.5SMC13A offers higher surge margin due to larger thermal mass but requires more PCB area; not AEC-Q101 qualified | Choose SMBG13A-E3/52 for space-constrained automotive or industrial designs where AEC-Q101 and compact SMBG footprint are mandatory |
Compared with SMBJ13A-E3/52 and 1.5SMC13A, SMBG13A-E3/52 uniquely combines AEC-Q101 qualification, DO-215AA low-profile packaging, and 100 °C/W thermal resistance - making it optimal for high-reliability, space-limited 12 V system protection where automotive qualification and thermal efficiency are prioritized over raw surge margin or cost.

FAQ
What is the clamping voltage of SMBG13A-E3/52 at its rated peak pulse current?
The SMBG13A-E3/52 has a maximum clamping voltage (VC) of 21.5 V at its rated peak pulse current (IPPM) of 27.9 A, measured using a 10/1000 µs waveform. This value ensures downstream ICs see limited overvoltage during surge events. The SMBG13A-E3/52 maintains this clamping performance across its full operating temperature range (–55 °C to +150 °C), as confirmed in Vishay Document 88456.
Is SMBG13A-E3/52 suitable for automotive applications?
Yes, SMBG13A-E3/52 is AEC-Q101 qualified and UL 497B recognized (file E136766), making it suitable for automotive applications including engine control units, body electronics, and ADAS sensor interfaces. Its 100 A IFSM rating supports load-dump immunity, and its MSL Level 1 rating ensures compatibility with lead-free reflow. The SMBG13A-E3/52 meets these requirements without derating in under-hood environments up to +150 °C.
What does the "E3/52" suffix indicate in SMBG13A-E3/52?
The "E3" suffix denotes RoHS-compliant, industrial-grade construction with matte tin-plated leads; "/52" specifies packaging in 7″ diameter plastic tape and reel, with 750 units per reel. This format ensures compatibility with automated SMT placement equipment and satisfies IPC/JEDEC standards for solderability and whisker resistance (JESD 201 Class 2). The SMBG13A-E3/52 ordering code is explicitly listed in Vishay's official ordering table.
How does SMBG13A-E3/52 differ from bidirectional variants like SMBG13CA?
SMBG13A-E3/52 is unidirectional, with polarity marked by a cathode band and forward conduction capability, whereas SMBG13CA is bidirectional and symmetrical - lacking polarity marking and conducting in both directions. The SMBG13A-E3/52 has a specified forward voltage drop (VF = 3.5 V at 50 A), while SMBG13CA does not. Use SMBG13A-E3/52 for DC-biased lines (e.g., 12 V rails); use SMBG13CA for AC or differential lines (e.g., RS-485).
What is the thermal resistance of SMBG13A-E3/52, and how does it affect layout?
The SMBG13A-E3/52 has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 5.0 mm × 5.0 mm copper pads per terminal. To maintain safe junction temperatures during repetitive surges, PCB layout must provide adequate copper area and thermal vias - especially critical in automotive applications where ambient temperatures exceed 105 °C. This RθJA value is measured per JEDEC standards and documented in Vishay's SMBG5.0A–SMBG188CA datasheet (Rev. 09-Jan-2024).
