Product details
Overview
SMB10J5.0A-M3/5B 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, 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-M3/5B datasheet, SMB10J5.0A-M3/5B pinout, SMB10J5.0A-M3/5B application, or SMB10J5.0A-M3/5B equivalent, key selection criteria include its AEC-Q101 qualification, halogen-free RoHS-compliant M3 suffix, 150 °C max junction temperature, and verified clamping performance under repetitive 10/1000 µs surges per ANSI/IEEE C62.35.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds its 6.4–7.07 V breakdown range, it avalanches rapidly (<1 ns response) to divert surge current away from downstream ICs. Its low incremental surge resistance ensures minimal voltage overshoot during 108.7 A peak pulses.
Designed for surface-mount automation, it uses a glass-passivated silicon junction and matte tin-plated leads compliant with J-STD-002 solderability and JESD22-B102 whisker testing. The SMB package supports MSL Level 1 handling and 260 °C reflow peak temperature.
Key Specifications

IC Role / Device Role / Timing Role: Standoff-rated TVS on 24 V or 5 V input rails, absorbing repetitive 10/1000 µs transients up to 108.7 A. Use Value: Prevents latch-up or damage in microcontroller GPIOs and level-shifters with verified 150 °C operating range. |
| Consumer Power Rail Protection | Telecom Data Line Protection |
Use Scenario: Securing USB VBUS, HDMI power pins, or PMIC input rails in portable electronics against ESD and hot-swap transients. IC Role / Device Role / Timing Role: Primary overvoltage clamp on 5.0 V supply path, positioned upstream of LDOs or DC-DC converters. Use Value: Delivers 1000 W surge rating with <1 ns response, enabling compact layout without external series impedance. | Use Scenario: Protecting Ethernet PHY bias rails or RS-485 termination networks from lightning-induced surges. IC Role / Device Role / Timing Role: Low-capacitance unidirectional TVS on DC bias lines feeding transformer-coupled data interfaces. Use Value: Clamps to ≤9.2 V while maintaining signal fidelity due to stable VBR tolerance (±5%) and minimal leakage (<1000 µA at 5.0 V). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ5.0A-M3/5B | Same SMB package, identical VWM = 5.0 V and VC ≤ 9.2 V, but rated for 600 W PPPM (vs. 1000 W) | Limited to lower-energy transients; not suitable for automotive load-dump scenarios requiring 1000 W | Select SMB10J5.0A-M3/5B where full 1000 W surge immunity is required per ISO 16750-2 |
| 1.5SMC5.0A-M3/5B | Higher-power SMC package (1500 W), same VWM/VBR specs, but larger footprint (7.11 mm × 6.22 mm) | Requires PCB redesign; used where higher energy margin or legacy SMC footprint is mandated | Choose SMB10J5.0A-M3/5B for space-constrained designs needing 1000 W in SMB outline |
Compared with SMBJ5.0A-M3/5B and 1.5SMC5.0A-M3/5B, the SMB10J5.0A-M3/5B uniquely balances 1000 W surge capability with SMB's compact size and AEC-Q101 qualification - making it optimal for next-gen automotive ECUs and industrial edge controllers where board area and reliability are co-constrained.

FAQ
What is the breakdown voltage range of the SMB10J5.0A-M3/5B?
The SMB10J5.0A-M3/5B has a guaranteed breakdown voltage (VBR) range of 6.4 V to 7.07 V at 10 mA test current, measured per ANSI/IEEE C62.35. This tight tolerance ensures consistent avalanche triggering across production lots and supports precise 5.0 V rail protection without premature conduction.
Is the SMB10J5.0A-M3/5B suitable for automotive applications?
Yes, the SMB10J5.0A-M3/5B is AEC-Q101 qualified and manufactured with halogen-free, RoHS-compliant materials (M3 suffix). Its -55 °C to +150 °C operating range, 1000 W peak pulse rating, and validation against load-dump and ESD stress make it approved for under-hood and body-control module use in automotive systems.
How does the clamping voltage of SMB10J5.0A-M3/5B compare to its stand-off voltage?
The SMB10J5.0A-M3/5B has a stand-off voltage (VWM) of 5.0 V and clamps to ≤9.2 V at its rated peak pulse current of 108.7 A. This 4.2 V headroom allows safe operation of 5 V logic devices while ensuring fast, low-overshoot suppression of transients exceeding the breakdown threshold.
What packaging format is supplied for SMB10J5.0A-M3/5B?
The SMB10J5.0A-M3/5B is supplied in 13-inch diameter plastic tape and reel, with a base quantity of 3200 units per reel (package code 5B). This format supports high-volume automated assembly and complies with EIA-481 standards for SMT placement accuracy.
Does SMB10J5.0A-M3/5B require derating at elevated ambient temperatures?
Yes, the SMB10J5.0A-M3/5B must be derated above 25 °C ambient per Figure 2 in Vishay document 88422. At 85 °C ambient, its 1000 W peak pulse power drops to approximately 650 W, and at 125 °C, it falls to ~400 W - requiring system-level thermal design to maintain effective surge margin.
