Product details
Overview
SMBG13CHE3/52 from Vishay General Semiconductor is a bi-directional transient voltage suppressor (TVS) diode in DO-215AA (SMBG) package, designed for clamping voltage transients on signal or power lines. It features 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.
For engineers reviewing the SMBG13CHE3/52 datasheet, SMBG13CHE3/52 pinout, SMBG13CHE3/52 application, or SMBG13CHE3/52 equivalent, this AEC-Q101 qualified, RoHS-compliant TVS diode supports automotive-grade ESD and surge protection in sensor interfaces, power supply rails, and communication lines where bidirectional clamping and low leakage (<1.0 μA at VWM) are required.
Technical Context
The SMBG13CHE3/52 operates as a bi-directional avalanche diode, symmetrically clamping positive and negative transients above its breakdown threshold. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low incremental surge resistance, enabling consistent clamping performance under repetitive 10/1000 μs surges at 0.01% duty cycle.
Thermal design is supported by RθJA = 100 °C/W and RθJL = 20 °C/W, with operation rated from –55 °C to +150 °C junction temperature. The device meets MSL Level 1 per J-STD-020 and is qualified to AEC-Q101 for automotive under-hood and infotainment applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 13 V - Maximum continuous reverse voltage before clamping begins; defines safe operating margin below breakdown |
| VBR (Breakdown Voltage) | 14.4–15.9 V at 1 mA - Ensures reliable turn-on during transients while avoiding false triggering at nominal rail voltages |
| VC (Clamping Voltage) | 21.5 V at IPPM = 27.9 A - Limits peak voltage seen by protected ICs during 600 W surge events |
| PPPM (Peak Pulse Power) | 600 W (10/1000 μs) - Supports robust protection against IEC 61000-4-5 Level 4 surges (4 kV line-to-earth) |
| ID (Reverse Leakage) | ≤1.0 μA at VWM - Minimizes standby power loss and avoids interference in high-impedance sensor circuits |
| TJ max. | +150 °C - Enables use in under-hood automotive environments without derating at full power |
| AEC-Q101 Qualified | Yes - Validated for automotive reliability including temperature cycling, HTRB, and ESD testing per AEC standard |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13CA-E3/52 | Same VWM/VBR/VC specs, but SMBJ package (DO-214AA); RθJA = 85 °C/W vs. 100 °C/W | Slightly higher thermal efficiency; larger footprint than SMBG | Select when board space allows larger package and lower thermal resistance is prioritized |
| 1.5KE13CA | Through-hole DO-201 package; same electrical specs but higher RθJA (~65 °C/W), no AEC-Q101 qualification | Not suitable for automotive; limited to industrial/commercial reflow or wave-soldered assemblies | Choose only for cost-sensitive, non-automotive designs where manual assembly or legacy through-hole is required |
Compared with SMBJ13CA-E3/52 and 1.5KE13CA, the SMBG13CHE3/52 offers AEC-Q101 qualification and DO-215AA's compact gull-wing footprint-critical for space-constrained automotive PCBs-while trading minor thermal resistance for manufacturability and reliability assurance.

FAQ
What is the polarity configuration of SMBG13CHE3/52?
The SMBG13CHE3/52 is a bi-directional TVS diode with symmetrical anode/cathode terminals and no polarity marking. It clamps voltage transients equally in both directions above its breakdown threshold (14.4–15.9 V), making it ideal for AC-coupled or floating signal lines where polarity cannot be assumed. This eliminates orientation errors during automated placement.
Does SMBG13CHE3/52 meet automotive qualification standards?
Yes, SMBG13CHE3/52 carries the HE3 suffix, confirming AEC-Q101 qualification per Vishay's ordering documentation. It has undergone stress testing including temperature cycling, high-temperature reverse bias (HTRB), and ESD per AEC-Q101 Rev D, validating its suitability for under-hood and cabin electronics in passenger vehicles and commercial vehicles.
What is the maximum clamping voltage of SMBG13CHE3/52 under surge conditions?
The SMBG13CHE3/52 exhibits a maximum clamping voltage (VC) of 21.5 V at its rated peak pulse current (IPPM) of 27.9 A, measured with a 10/1000 μs waveform. This value is guaranteed across the full operating temperature range (–55 °C to +150 °C) and ensures protected downstream ICs experience no more than 21.5 V during standardized surge events.
How does the DO-215AA (SMBG) package of SMBG13CHE3/52 compare to DO-214AA (SMBJ)?
The DO-215AA (SMBG) package used by SMBG13CHE3/52 is dimensionally smaller than DO-214AA (SMBJ), with tighter lead spacing and lower profile. While SMBG offers superior board-space efficiency, its thermal resistance (RθJA = 100 °C/W) is slightly higher than SMBJ's (85 °C/W). Both are RoHS-compliant and AEC-Q101 qualified when specified with HE3 suffix.
Is SMBG13CHE3/52 compatible with lead-free reflow processes?
Yes, SMBG13CHE3/52 is rated for lead-free reflow with a maximum peak temperature of 260 °C per J-STD-020, meeting MSL Level 1 requirements. Its matte tin-plated leads comply with J-STD-002 and JESD 22-B102 solderability standards, and the HE3 variant passes JESD 201 Class 2 whisker testing-ensuring robust interconnect reliability in high-volume SMT assembly.
