Product details
Overview
SMB10J5.0A-E3/5B from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for high-energy surge protection on 5.0 V DC power rails and signal lines. It delivers 1000 W peak pulse power (10/1000 µs), clamps transients to ≤9.2 V at 108.7 A peak surge current, and features 6.4–7.07 V breakdown voltage at 10 mA test current - ideal for safeguarding automotive sensor interfaces and industrial I/O circuits.
For engineers reviewing the SMB10J5.0A-E3/5B datasheet, SMB10J5.0A-E3/5B pinout, SMB10J5.0A-E3/5B application, or SMB10J5.0A-E3/5B equivalent, key selection criteria include its AEC-Q101 qualification, low clamping voltage (VC = 9.2 V), RoHS-compliant matte tin terminals, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector: under normal conditions it presents <1000 nA leakage at 5.0 V standoff, then rapidly avalanches when transient voltage exceeds its 6.4–7.07 V breakdown range. Its glass-passivated junction ensures stable VBR over temperature and lifetime.
Thermal performance is defined by RθJA = 72 °C/W and RθJL = 20 °C/W, enabling reliable operation up to TJ = +150 °C. The device meets MSL Level 1 per J-STD-020 and supports peak forward surge current of 100 A (8.3 ms half-sine), making it suitable for automotive load-dump and inductive-switching transient suppression.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ5.0A-E3/52 | Same SMB package, identical 5.0 V VWM and 9.2 V VC, but rated for 600 W PPPM (vs. 1000 W) | Limited to lower-energy transients; not qualified to AEC-Q101 | Select SMBJ5.0A-E3/52 only for cost-sensitive consumer applications where 600 W surge margin suffices |
| 1.5SMC5.0A | Higher-power SMC package (1500 W PPPM), same 5.0 V VWM and 9.2 V VC, but larger footprint (7.11 mm × 6.22 mm) | Requires PCB redesign; better suited for high-reliability industrial mains-input protection | Choose 1.5SMC5.0A when system-level surge testing exceeds 1000 W or when thermal derating margin is critical |
Compared with SMBJ5.0A-E3/52 and 1.5SMC5.0A, SMB10J5.0A-E3/5B uniquely balances 1000 W surge capability, AEC-Q101 qualification, and compact SMB footprint - making it optimal for space-constrained automotive and industrial modules requiring automotive-grade robustness without board real estate penalty.

FAQ
What is the maximum clamping voltage of SMB10J5.0A-E3/5B at its rated peak pulse current?
The SMB10J5.0A-E3/5B has a maximum clamping voltage (VC) of 9.2 V at its peak pulse current (IPPM) of 108.7 A, measured under the standardized 10/1000 µs waveform. This value is guaranteed per Vishay's datasheet revision 09-Jan-2024 (Document Number: 88422) and reflects the actual voltage seen by downstream circuitry during worst-case surge events. Maintaining VC this low at high IPPM ensures robust protection for 5 V logic and interface ICs.
Is SMB10J5.0A-E3/5B qualified for automotive use?
Yes, SMB10J5.0A-E3/5B is RoHS-compliant and commercially rated; however, its AEC-Q101 qualification applies specifically to variants with HE3 or HM3 suffixes (e.g., SMB10J5.0AHE3_B/I). The "E3/5B" suffix denotes RoHS compliance and 13-inch tape-and-reel packaging but does not itself carry AEC-Q101 certification. For automotive designs, specify the HE3 or HM3 version to ensure full qualification.
What is the standoff voltage (VWM) and why is it critical for SMB10J5.0A-E3/5B placement?
The standoff voltage (VWM) of SMB10J5.0A-E3/5B is 5.0 V - the maximum continuous reverse voltage it can block without significant leakage. This matches standard 5 V supply rails, allowing the device to remain fully inactive during normal operation while still responding instantly to overvoltage events. Selecting a VWM equal to the system rail prevents false triggering and minimizes standby current (<1000 µA), which is essential for battery-powered and low-power sensor nodes.
How does the SMB (DO-214AA) package of SMB10J5.0A-E3/5B impact thermal performance?
The SMB (DO-214AA) package of SMB10J5.0A-E3/5B provides a thermal resistance of RθJA = 72 °C/W (junction-to-ambient) and RθJL = 20 °C/W (junction-to-lead) when mounted on 0.2" × 0.2" copper pads. This enables effective heat dissipation during repetitive surge events and supports continuous operation up to +150 °C junction temperature. The low-profile design also facilitates dense PCB layouts without compromising thermal reliability.
Can SMB10J5.0A-E3/5B be used in bidirectional configurations?
No - SMB10J5.0A-E3/5B is a unidirectional TVS diode, identifiable by its cathode band marking. Bidirectional protection requires a distinct part number such as SMB8J5.0CA (which offers 800 W PPPM and symmetric clamping). Using SMB10J5.0A-E3/5B in reverse-biased configurations risks permanent breakdown, as it is not characterized or rated for reverse conduction beyond its specified VWM and leakage limits.
