Product details
Overview
SMB8J6.0C-E3/5B 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 6.0 V stand-off voltage (VWM), 10.3 V maximum clamping voltage (VC) at 2000 A peak pulse current (IPPM), and 800 W peak pulse power (PPPM) with 10/1000 µs waveform - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the SMB8J6.0C-E3/5B datasheet, SMB8J6.0C-E3/5B pinout, SMB8J6.0C-E3/5B application, or SMB8J6.0C-E3/5B equivalent, key selection criteria include bi-directional clamping capability, AEC-Q101 qualification, low clamping ratio (VC/VWM = 1.72), 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, enabling robust protection against ESD, lightning-induced transients, and inductive switching spikes without polarity sensitivity. Its glass-passivated junction ensures stable breakdown behavior and low leakage (<1.0 µA at VWM), while thermal resistance (RθJA = 72 °C/W) supports operation up to 150 °C junction temperature.
The device complies with ANSI/IEEE C62.35 standards for transient suppression and meets J-STD-020 MSL Level 1 (peak reflow 260 °C). Its 2000 A IPPM rating at 10/1000 µs is validated under derated conditions per Fig. 2, with clamping performance specified at TA = 25 °C on minimum recommended pad layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum continuous reverse operating voltage before conduction begins; defines safe signal line bias margin. |
| VBR (min/max) | 6.67 V / 7.37 V - Breakdown occurs within this range at 10 mA test current; ensures reliable turn-on during transients. |
| VC @ IPPM | 10.3 V - Clamps 2000 A surge (10/1000 µs) to ≤10.3 V, limiting downstream IC stress to safe levels. |
| PPPM | 800 W - Peak pulse power handling capacity; determines survivability against standardized lightning surges. |
| ID @ VWM | ≤1.0 µA - Reverse leakage at rated stand-off voltage; critical for low-power sensor and battery-backed circuits. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.0CA | Same VWM (6.0 V), but lower IPPM (1000 A) and PPPM (600 W); non-AEC-Q101, commercial grade only. | Limited to consumer or non-automotive industrial use where surge severity is lower and qualification not required. | Select when cost sensitivity outweighs automotive reliability requirements and surge energy stays below 600 W. |
| SMCJ6.0A | Uni-directional, higher PPPM (1500 W), larger DO-214AB (SMC) package; VWM = 6.0 V, VC = 10.3 V, but polarity-sensitive. | Requires explicit cathode orientation; unsuitable for AC or floating lines unless external rectification is added. | Choose only for unidirectional DC rails where board space allows larger SMC package and polarity is fixed. |
