Product details
Overview
SMB10J7.0A-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 DC power rails and signal lines. It features a 7.0 V stand-off voltage (VWM), 7.78–8.60 V breakdown voltage (VBR) at 10 mA, 12.0 V clamping voltage (VC) at 83.3 A peak pulse current (IPPM), and 1000 W peak pulse power (PPPM) with 10/1000 µs waveform - used in automotive power supply input stages and industrial sensor interface protection.
For engineers reviewing the SMB10J7.0A-E3/5B datasheet, SMB10J7.0A-E3/5B pinout, SMB10J7.0A-E3/5B application, or SMB10J7.0A-E3/5B equivalent, key selection criteria include clamping performance under 83.3 A surge, AEC-Q101 qualification status, RoHS-compliant E3 suffix, and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector, responding within picoseconds to transients exceeding its VWM. Its glass-passivated junction ensures stable breakdown behavior and low leakage (<1000 µA at VWM), while the low incremental surge resistance enables effective energy diversion during 10/1000 µs surges up to 1000 W.
The device is rated for -55 °C to +150 °C operating junction temperature and meets MSL level 1 per J-STD-020 (260 °C peak reflow). Its thermal resistance (RθJA = 72 °C/W) and RθJL = 20 °C/W support reliable power dissipation in compact PCB layouts with minimum recommended pad area.
Key Specifications
| Parameter | Value and Actual Design Meaning |

IC Role / Device Role / Timing Role: Shunt TVS placed upstream of LDO or DC-DC converter input to clamp transients before regulation stage. Use Value: Limits voltage to ≤12.0 V during 83.3 A surge, preventing damage to downstream regulators rated for 16 V absolute max. | Use Scenario: Analog output lines (e.g., 4–20 mA, 0–5 V) from pressure/temperature sensors in factory automation. IC Role / Device Role / Timing Role: Bidirectional protection not applicable; this unidirectional part used on supply-referenced signal paths where polarity is fixed. Use Value: Clamps induced ESD or switching noise to 12.0 V while maintaining <1000 µA leakage for accurate low-current measurement. |
| Consumer Power Adapter Interface | Telecom DC Power Feeds |

IC Role / Device Role / Timing Role: Unidirectional TVS on positive rail referenced to system ground; cathode tied to +48 V line. Use Value: Withstands repeated 10/1000 µs surges up to 83.3 A while maintaining VWM = 7.0 V margin below nominal rail. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ7.0A-E3/5B | Same SMB package, identical VWM/VBR/VC specs, but lower PPPM (600 W vs. 1000 W) | Not suitable for 1000 W surge requirements; limited to lower-energy transients | Select only if system-level testing confirms 600 W clamping margin is sufficient |
| SMB10J7.0AHE3_B/I | Same electrical specs and AEC-Q101 qualification; differs only in tape-and-reel packaging (3200 pcs on 13" reel vs. 3200 pcs on 13" reel with /5B code) | No functional difference; both meet automotive reliability requirements | Prefer SMB10J7.0A-E3/5B for standard commercial logistics; use HE3 variant only for traceability-critical OEM programs |
Compared with SMBJ7.0A-E3/5B and SMB10J7.0AHE3_B/I, the SMB10J7.0A-E3/5B delivers full 1000 W surge capability in a qualified automotive-grade package with standardized E3 RoHS compliance and 13" reel delivery - making it the optimal choice for high-reliability 12 V rail protection where peak power handling is critical.

FAQ
What is the clamping voltage of SMB10J7.0A-E3/5B at its rated peak pulse current?
The SMB10J7.0A-E3/5B has a maximum clamping voltage (VC) of 12.0 V when subjected to its rated peak pulse current (IPPM) of 83.3 A using the standard 10/1000 µs waveform. This value is measured under defined test conditions per ANSI/IEEE C62.35 and ensures predictable overvoltage limiting for downstream components connected to the protected line.
Is SMB10J7.0A-E3/5B qualified for automotive applications?
Yes, SMB10J7.0A-E3/5B is AEC-Q101 qualified, having passed stress tests including high-temperature reverse bias, temperature cycling, and accelerated life testing required for automotive under-hood and chassis-mounted electronics. The E3 suffix confirms RoHS compliance, and the device is rated for operation from -55 °C to +150 °C junction temperature.
What does the "/5B" suffix indicate in SMB10J7.0A-E3/5B?
The "/5B" suffix in SMB10J7.0A-E3/5B specifies the packaging configuration: 3200 units per 13-inch diameter plastic tape-and-reel. This format supports high-volume automated assembly and is distinct from "/52" (750 units on 7-inch reel). The "E3" denotes RoHS-compliant commercial-grade construction with matte tin plating.
How does SMB10J7.0A-E3/5B differ from bidirectional variants like SMB8J7.0CA?
SMB10J7.0A-E3/5B is unidirectional with cathode marking and conducts only in reverse breakdown, whereas SMB8J7.0CA is bidirectional and symmetrical. The SMB10J7.0A-E3/5B offers higher peak pulse power (1000 W vs. 800 W) and is optimized for DC rail protection with polarity-defined placement, unlike bidirectional types used on AC or floating signal lines.
What is the thermal resistance of SMB10J7.0A-E3/5B, and how does it affect layout design?
SMB10J7.0A-E3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 72 °C/W and junction-to-lead (RθJL) of 20 °C/W. To maintain safe operation under repeated surges, PCB layout must use minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal - reducing thermal impedance and preventing junction overheating beyond the +150 °C limit.
