Product details
Overview
SMB10J15HE3/5B from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-214AA (SMB) package, designed for high-energy surge protection on power and signal lines. It features a 15 V standoff voltage (VWM), 16.7–18.5 V breakdown voltage (VBR), 24.4 V clamping voltage (VC) at 41.0 A peak pulse current (IPPM), and 1000 W peak pulse power (PPPM) with 10/1000 µs waveform - deployed in automotive ECUs, industrial motor drives, and DC power input stages.
For engineers reviewing the SMB10J15HE3/5B datasheet, SMB10J15HE3/5B pinout, SMB10J15HE3/5B application, or SMB10J15HE3/5B equivalent, key selection criteria include AEC-Q101 qualification, unidirectional polarity with cathode band marking, low incremental surge resistance, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a clamping device that enters avalanche conduction when reverse voltage exceeds its breakdown threshold (VBR = 16.7–18.5 V at IT = 1.0 mA), limiting transient-induced overvoltage to ≤24.4 V at 41.0 A. Its glass-passivated junction ensures stable leakage performance (<1.0 µA at VWM = 15 V) and fast response time (<1 ns).
Thermally, it sustains operation from –55 °C to +150 °C junction temperature, with RθJA = 72 °C/W and RθJL = 20 °C/W. The HE3 suffix confirms AEC-Q101 qualification and JESD 201 Class 2 whisker resistance, making it suitable for under-hood automotive environments where reliability under thermal cycling and vibration is critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 15 V - maximum continuous reverse operating voltage before clamping begins; defines safe DC/AC working range on protected line |
| VBR (min/max) | 16.7 V / 18.5 V - breakdown occurs within this range at 1.0 mA test current; ensures consistent turn-on across production lots |
| VC @ IPPM | 24.4 V at 41.0 A - clamped voltage during 10/1000 µs surge; determines maximum stress imposed on downstream ICs |
| PPPM | 1000 W - peak pulse power handling capability; enables protection against IEC 61000-4-5 Level 4 surges (4 kV/2 Ω) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ15A-E3/5B | Same DO-214AA package, identical VWM/VBR/VC specs, but lacks AEC-Q101 qualification and HE3 whisker rating | Approved for commercial/industrial use only; not certified for automotive under-hood deployment | Select when AEC-Q101 is not required and cost optimization is prioritized |
| 1.5SMC15A | DO-214AB (SMC) package - larger footprint (7.11 mm × 6.22 mm), higher thermal mass, RθJA = 25 °C/W vs. 72 °C/W | Better sustained power handling in non-SMT-limited designs; requires more PCB area and different pad layout | Choose when board space permits and higher thermal dissipation is needed for repetitive surge events |
Compared with SMBJ15A-E3/5B, SMB10J15HE3/5B adds automotive qualification and enhanced whisker resistance; compared with 1.5SMC15A, it offers smaller size and tighter board integration at the expense of lower thermal derating margin.

FAQ
What is the clamping voltage of SMB10J15HE3/5B at its rated peak pulse current?
The SMB10J15HE3/5B has a maximum clamping voltage (VC) of 24.4 V when subjected to its peak pulse current (IPPM) of 41.0 A under the standard 10/1000 µs waveform. This value is measured at TA = 25 °C with specified PCB pad layout (0.2" × 0.2" copper). The SMB10J15HE3/5B maintains this clamping performance across its full operating temperature range, ensuring predictable protection for downstream ICs.
Is SMB10J15HE3/5B suitable for automotive applications?
Yes, SMB10J15HE3/5B is AEC-Q101 qualified and carries the HE3 suffix indicating compliance with JESD 201 Class 2 whisker testing. It operates reliably from –55 °C to +150 °C and meets MSL Level 1 for lead-free reflow. These attributes make SMB10J15HE3/5B appropriate for engine control units, body electronics, and ADAS modules where environmental ruggedness is mandatory.
How does the HE3 suffix differ from E3 in Vishay SMBJ part numbering?
The HE3 suffix in SMB10J15HE3/5B denotes AEC-Q101 qualification and JESD 201 Class 2 whisker resistance, whereas E3 indicates RoHS-compliant commercial grade only. Both share the same electrical specs and DO-214AA package, but HE3 parts undergo additional stress testing for automotive use. The SMB10J15HE3/5B is therefore validated for under-hood deployment where vibration, thermal cycling, and long-term reliability are critical.
What is the reverse leakage current of SMB10J15HE3/5B at its standoff voltage?
At its 15 V standoff voltage (VWM) and TA = 25 °C, the SMB10J15HE3/5B exhibits a maximum reverse leakage current (ID) of 1.0 µA. This ultra-low leakage preserves efficiency in battery-backed systems and avoids false triggering in high-impedance sensing circuits. The SMB10J15HE3/5B maintains leakage below 5.0 µA even at TJ = 125 °C, supporting stable operation in thermally demanding environments.
Can SMB10J15HE3/5B be used in bi-directional protection configurations?
No - SMB10J15HE3/5B is a unidirectional TVS diode, identifiable by its cathode band marking. For bi-directional protection, Vishay offers the SMB8J15CA variant (with 'C' in the part number), which provides symmetrical clamping for AC lines or data buses. Using SMB10J15HE3/5B in reverse-biased mode would result in forward conduction and failure; always verify polarity during PCB layout and assembly of SMB10J15HE3/5B.
