Product details
Overview
SMB10J5.0-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 5.0 V stand-off voltage (VWM), 6.4–7.07 V breakdown voltage (VBR) at 10 mA, 1000 W peak pulse power (10/1000 µs), 108.7 V clamping voltage at 108.7 A peak surge current, and AEC-Q101 qualification for automotive use.
For engineers reviewing the SMB10J5.0-E3/5B datasheet, SMB10J5.0-E3/5B pinout, SMB10J5.0-E3/5B application, or SMB10J5.0-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, MSL Level 1 reflow compatibility, and thermal resistance (RθJA = 72 °C/W) for board-level thermal design.
Technical Context
This TVS diode operates as a voltage-clamped crowbar device triggered by reverse-biased avalanche breakdown. Its glass-passivated junction ensures stable VBR tolerance and low leakage (<1000 µA at VWM), while the low incremental surge resistance enables rapid energy diversion during ESD or lightning-induced transients.
The SMB10J5.0-E3/5B is rated for -55 °C to +150 °C operating junction temperature, supports 100 A non-repetitive forward surge (8.3 ms half-sine), and meets ANSI/IEEE C62.35 standards for transient suppression. Its DO-214AA package provides mechanical robustness and solderability per J-STD-002 and JESD 22-B102.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.0 V - Maximum continuous reverse working voltage before clamping begins; defines safe DC rail operating margin. |
| VBR min/max | 6.4 V / 7.07 V at 10 mA - Tight breakdown window ensures predictable turn-on without premature conduction. |
| VC @ IPPM | 9.2 V at 108.7 A - Clamping voltage during 10/1000 µs surge; determines maximum stress on protected ICs. |
| PPPM | 1000 W - Peak pulse power handling capacity; defines survivability against IEC 61000-4-5 Level 4 surges. |
| RθJA | 72 °C/W - Junction-to-ambient thermal resistance; guides copper pad sizing (0.2" × 0.2") for thermal derating. |
| Polarity | Unidirectional - Cathode-banded configuration protects positive DC rails only; requires correct orientation in PCB layout. |
| Qualification | AEC-Q101 qualified - Validated for automotive under-hood and infotainment applications per stress test requirements. |

| Cathode | High-side connection to protected line (e.g., +5 V rail) | Marked with band; reverse-biased during normal operation; avalanches to shunt surge to ground. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable VBR over temperature and lifetime; eliminates passivation-related leakage drift. |
| MSL Level 1 rating | Supports lead-free reflow up to 260 °C peak without moisture-induced popcorning. |

Use Value: Low 5.0 V VWM allows integration upstream of buck converters without affecting regulation; 9.2 V VC prevents PD controller overvoltage shutdown. | Use Scenario: Secondary-side transient suppression on -48 V DC feeder lines powering remote radio units in 5G base stations. IC Role / Device Role / Timing Role: Unidirectional configuration referenced to negative rail absorbs positive-going surges induced by lightning coupling. Use Value: AEC-Q101 qualification ensures reliability in outdoor telecom environments; 72 °C/W RθJA enables thermal management on limited copper area. |
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-E3/5B | Same DO-214AA package, identical VWM/VBR/VC specs, but rated for 600 W PPPM (vs. 1000 W). | Limited to lower-energy transients (e.g., IEC 61000-4-2 ESD only); insufficient for IEC 61000-4-5 surge testing. | Select SMB10J5.0-E3/5B when full 1000 W surge immunity is required; SMBJ5.0A-E3/5B suits cost-sensitive, lower-risk consumer interfaces. |
| 1.5SMC5.0A | DO-214AB (SMC) package, same electrical specs, higher RθJA (50 °C/W), larger footprint (7.11 mm × 6.22 mm). | Requires more PCB area; better thermal dissipation in high-ambient environments but incompatible with SMB footprints. | Choose 1.5SMC5.0A only if board layout allows larger SMC pad geometry and thermal performance outweighs space constraints. |
Compared with SMBJ5.0A-E3/5B and 1.5SMC5.0A, SMB10J5.0-E3/5B delivers superior 1000 W surge handling in the compact DO-214AA footprint while maintaining AEC-Q101 qualification-making it optimal for space-constrained automotive and industrial power rail protection where both energy rating and reliability are critical.

FAQ
What is the clamping voltage of SMB10J5.0-E3/5B at its rated peak pulse current?
The SMB10J5.0-E3/5B has a maximum clamping voltage (VC) of 9.2 V at its peak pulse current (IPPM) of 108.7 A under a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during worst-case surge events. The SMB10J5.0-E3/5B maintains this clamping performance across its specified operating temperature range.
Is SMB10J5.0-E3/5B suitable for automotive applications?
Yes, SMB10J5.0-E3/5B is AEC-Q101 qualified and explicitly rated for automotive use, including engine control units, infotainment systems, and ADAS sensor modules. Its construction-glass-passivated junction, MSL Level 1 reflow capability, JESD 201 Class 1A whisker resistance, and -55 °C to +150 °C operating range-meets automotive reliability requirements. The SMB10J5.0-E3/5B data sheet confirms qualification per AEC-Q101 test conditions.
How does the SMB10J5.0-E3/5B differ from the SMBJ5.0A-E3/5B?
The SMB10J5.0-E3/5B delivers 1000 W peak pulse power (10/1000 µs), whereas the SMBJ5.0A-E3/5B is rated for 600 W. Both share identical VWM (5.0 V), VBR (6.4–7.07 V), VC (9.2 V), and DO-214AA packaging. The SMB10J5.0-E3/5B achieves higher power handling via optimized chip geometry and thermal design. For designs requiring IEC 61000-4-5 Level 4 immunity, SMB10J5.0-E3/5B is necessary; SMBJ5.0A-E3/5B suffices for lower-energy ESD-only protection.
What is the thermal resistance of SMB10J5.0-E3/5B, and how does it affect layout?
The SMB10J5.0-E3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 72 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value directly impacts PCB copper area requirements: reducing pad size increases RθJA, raising junction temperature during repeated surges. Layout must follow Vishay's recommended mounting pad dimensions to ensure thermal derating curves (Fig. 2) remain valid. The SMB10J5.0-E3/5B thermal performance is validated only with this pad configuration.
Does SMB10J5.0-E3/5B have bidirectional capability?
No, SMB10J5.0-E3/5B is a unidirectional TVS diode, indicated by the "J" (not "JCA") suffix and cathode band marking. It conducts only during reverse-biased overvoltage events on positive rails. Bidirectional variants (e.g., SMB8J5.0CA) exist in the same family but feature different breakdown symmetry and lack polarity marking. Using SMB10J5.0-E3/5B on AC or bipolar signal lines would result in unintended forward conduction; always verify polarity alignment in schematic and layout for the SMB10J5.0-E3/5B.
