Overview
SMB10J17-E3/5B from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-214AA (SMB) package, designed for high-energy surge protection on DC power rails and signal lines. It features a 17 V standoff voltage (VWM), 18.9–20.9 V breakdown voltage (VBR), 27.6 V clamping voltage (VC) at 36.2 A peak pulse current (IPPM), and 1000 W peak pulse power (PPPM) with 10/1000 µs waveform. It is AEC-Q101 qualified and used in automotive power supply input stages.
For engineers reviewing the SMB10J17-E3/5B datasheet, SMB10J17-E3/5B pinout, SMB10J17-E3/5B application, or SMB10J17-E3/5B equivalent, key selection criteria include clamping performance under 10/1000 µs transients, unidirectional polarity for DC rail protection, RoHS-compliant matte tin terminations, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a voltage-clamping device triggered by transient overvoltage events exceeding its breakdown threshold. Its glass-passivated junction ensures stable avalanche behavior, low incremental surge resistance, and fast response time (<1 ns), enabling effective suppression of ESD, load dump, and inductive switching spikes.
The device is rated for -55 °C to +150 °C operating junction temperature, with thermal resistance of 72 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead). It meets MSL Level 1 per J-STD-020 and passes JESD201 Class 1A whisker testing - critical for automotive and industrial reflow reliability.

FAQ
What is the clamping voltage of SMB10J17-E3/5B at its rated peak pulse current?
The SMB10J17-E3/5B has a maximum clamping voltage (VC) of 27.6 V when subjected to a 10/1000 µs waveform at its rated peak pulse current of 36.2 A. This value is measured per ANSI/IEEE C62.35 standards and defines the upper voltage limit imposed on protected circuits during surge events. The SMB10J17-E3/5B maintains this clamping performance across its specified operating temperature range.
Is SMB10J17-E3/5B suitable for automotive applications?
Yes, SMB10J17-E3/5B is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments. Its 150 °C maximum junction temperature, MSL Level 1 reflow compatibility, and JESD201 Class 1A whisker resistance meet stringent automotive manufacturing and reliability requirements. The SMB10J17-E3/5B is commonly deployed in engine control modules, body control units, and ADAS power supplies.
What does the "E3/5B" suffix indicate in SMB10J17-E3/5B?
The "E3" suffix denotes RoHS-compliant, commercial-grade construction with matte tin-plated leads meeting J-STD-002 solderability and JESD201 Class 1A whisker testing. The "5B" indicates packaging in 13-inch diameter plastic tape and reel, with a base quantity of 3200 units per reel - optimized for high-speed SMT placement. The SMB10J17-E3/5B is not AEC-Q101 qualified; for automotive-grade versions, the HE3 suffix is used.
How does SMB10J17-E3/5B differ from bi-directional variants like SMB8J17CA?
The SMB10J17-E3/5B is unidirectional and intended for DC rail protection where polarity is fixed, offering 1000 W peak pulse power and 36.2 A surge current. In contrast, SMB8J17CA is bi-directional with 800 W PPPM and 29.0 A IPPM, suited for AC or floating signal lines. The SMB10J17-E3/5B provides lower clamping voltage and higher surge capacity than SMB8J17CA in its intended unidirectional configuration.
What PCB layout guidance applies to SMB10J17-E3/5B for optimal thermal and electrical performance?
For rated 1000 W surge performance, Vishay specifies mounting SMB10J17-E3/5B on minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. Thermal relief traces should be minimized; direct copper pours improve heat dissipation and reduce impedance during surge conduction. The cathode band must align with schematic polarity, and adjacent high-dI/dt traces should be routed away to avoid coupling into the SMB10J17-E3/5B's low-inductance path.
