Product details
Overview
SMB8J10C-E3/52 from Vishay General Semiconductor is a bi-directional transient voltage suppressor (TVS) diode in DO-214AA (SMB) package, designed for high-energy surge protection on signal and power lines. It features 10 V stand-off voltage (VWM), 17.0 V maximum clamping voltage at 47.1 A peak pulse current (IPPM), and 800 W peak pulse power (PPPM) with 10/1000 µs waveform. Used to protect automotive sensor interfaces and industrial I/O lines against ESD and load dump transients.
For engineers reviewing the SMB8J10C-E3/52 datasheet, SMB8J10C-E3/52 pinout, SMB8J10C-E3/52 application, or SMB8J10C-E3/52 equivalent, key selection criteria include bi-directional clamping capability, AEC-Q101 qualification, RoHS-compliant matte tin terminations, and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
This bi-directional TVS operates symmetrically across both polarities, with breakdown voltage (VBR) of 11.1–12.3 V at 1.0 mA test current and reverse leakage ≤10 µA at 10 V. Its low incremental surge resistance enables fast response (<1 ns) to transients induced by inductive switching or lightning surges.
Thermal design is supported by RθJA = 72 °C/W and RθJL = 20 °C/W, enabling reliable operation up to 150 °C junction temperature. The device meets MSL level 1 per J-STD-020 and passes JESD 201 class 1A whisker testing.
Key Specifications

FAQ
What is the polarity configuration of SMB8J10C-E3/52?
SMB8J10C-E3/52 is a bi-directional TVS diode with symmetrical terminals-neither end is marked as anode or cathode. It clamps voltage transients of either polarity equally, making it ideal for AC-coupled or differential signal lines where polarity reversal may occur during fault conditions. This configuration eliminates orientation errors during automated placement.
Does SMB8J10C-E3/52 meet automotive qualification standards?
Yes, SMB8J10C-E3/52 is AEC-Q101 qualified, having passed stress tests including high-temperature reverse bias, temperature cycling, and humidity bias HAST. The "HE3" variant is explicitly designated for automotive use, but the E3/52 suffix also carries AEC-Q101 certification per Vishay documentation for the SMB8JxxC-A family, confirming suitability for under-hood and chassis-mounted applications.
What is the maximum clamping voltage for SMB8J10C-E3/52 under surge conditions?
The maximum clamping voltage (VC) for SMB8J10C-E3/52 is 17.0 V at 47.1 A peak pulse current (IPPM), measured with a 10/1000 µs waveform. This value represents the upper limit of voltage imposed on protected circuitry during worst-case transient events and is critical for ensuring downstream 3.3 V or 5 V ICs remain within absolute maximum ratings.
Can SMB8J10C-E3/52 be used in place of uni-directional TVS diodes?
No-SMB8J10C-E3/52 is strictly bi-directional and must not replace uni-directional TVS diodes in DC-biased circuits such as power supply rails. Using it in place of a uni-directional part like SMB10J10A would expose protected circuitry to forward conduction during normal operation, causing excessive leakage and potential malfunction. Always match polarity configuration to system bias architecture.
What PCB pad layout is recommended for SMB8J10C-E3/52?
Vishay specifies mounting SMB8J10C-E3/52 on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal to achieve rated 800 W pulse power. Smaller pads reduce thermal dissipation and cause premature failure under repeated surges. The DO-214AA outline requires 0.205" × 0.130" land pattern with 0.030" solder mask clearance per IPC-7351B guidelines.
