Product details
Overview
SMB10J17A-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 power and signal lines. It features a 17 V stand-off voltage (VWM), 18.9–20.9 V breakdown voltage (VBR at 1 mA), 27.6 V clamping voltage (VC) at 36.2 A peak pulse current, and 1000 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the SMB10J17A-E3/5B datasheet, SMB10J17A-E3/5B pinout, SMB10J17A-E3/5B application, or SMB10J17A-E3/5B equivalent, this page delivers verified electrical specs, AEC-Q101 qualification status, thermal resistance data, RoHS-compliant packaging details, and real-world use context for robust ESD/surge design validation.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector, responding within <1 ps to transients induced by inductive switching or ESD events. Its glass-passivated junction ensures stable leakage (<1 µA at VWM) and low incremental surge resistance, enabling precise clamping without thermal runaway under repetitive surges.
Designed for surface-mount automated assembly, it meets MSL Level 1 per J-STD-020 with 260 °C lead-free reflow compatibility and supports operation from –55 °C to +150 °C junction temperature. The device is AEC-Q101 qualified (via HE3/HM3 suffix variants), confirming suitability for automotive powertrain and body electronics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 17 V - Maximum continuous reverse operating voltage before conduction begins; defines safe working margin for 12 V automotive or 15 V industrial rails. |
| VBR (min/max) | 18.9 V / 20.9 V at 1 mA - Confirmed breakdown threshold range ensuring reliable triggering above normal operating voltage. |
| VC @ IPPM | 27.6 V at 36.2 A - Clamped voltage during 1000 W surge; limits downstream IC stress to sub-30 V level under worst-case transients. |
| PPPM | 1000 W (10/1000 µs) - Sustains high-energy surges common in load-dump or ISO 7637-2 Pulse 5a scenarios. |
| IFSM | 100 A (8.3 ms half-sine) - Withstands single-event overcurrents typical of motor driver flyback or relay coil de-energization. |
| RθJA | 72 °C/W - Thermal resistance enables stable operation on standard 5 mm × 5 mm copper pads without forced cooling. |
| Operating TJ | –55 °C to +150 °C - Full automotive-grade temperature range supporting under-hood and engine-control module deployment. |

FAQ
What is the clamping voltage of SMB10J17A-E3/5B at its rated peak pulse current?
The SMB10J17A-E3/5B has a maximum clamping voltage (VC) of 27.6 V at its peak pulse current (IPPM) of 36.2 A, measured under the standard 10/1000 µs waveform. This value ensures protected circuits remain below critical voltage thresholds during surge events, and is confirmed in Vishay's official datasheet revision 09-Jan-2024 (Document Number: 88422). The SMB10J17A-E3/5B maintains consistent clamping behavior across its operational temperature range.
Is SMB10J17A-E3/5B AEC-Q101 qualified?
No - SMB10J17A-E3/5B carries the commercial-grade E3 suffix and is RoHS-compliant but not AEC-Q101 qualified. AEC-Q101 qualification applies only to variants with HE3 or HM3 suffixes (e.g., SMB10J17AHE3_A). The SMB10J17A-E3/5B retains all electrical and thermal specifications of the family but lacks the extended reliability testing required for automotive qualification. Engineers requiring AEC-Q101 should specify SMB10J17AHE3_A instead of SMB10J17A-E3/5B.
What is the standoff voltage (VWM) and why does it matter for SMB10J17A-E3/5B?
The standoff voltage (VWM) of SMB10J17A-E3/5B is 17 V - the maximum DC or continuous reverse voltage the device can withstand without entering avalanche conduction. This parameter ensures reliable operation on 12 V or 15 V nominal systems, providing sufficient margin above normal rail voltage while avoiding false triggering. Exceeding VWM risks premature conduction and power loss; staying below it guarantees zero leakage (<1 µA) and stable protection readiness. For SMB10J17A-E3/5B, VWM directly informs system voltage selection and layout isolation requirements.
Can SMB10J17A-E3/5B be used in bidirectional configurations?
No - SMB10J17A-E3/5B is a unidirectional TVS diode, identifiable by its cathode band marking and specified electrical parameters (e.g., forward surge rating IFSM = 100 A). Bidirectional variants in the same family carry "C" in the part number (e.g., SMB10J17CA), with symmetrical breakdown and no forward surge rating. Using SMB10J17A-E3/5B in bidirectional applications would leave one polarity unprotected and risk catastrophic failure. Always match the SMB10J17A-E3/5B's unidirectional design to grounded-rail protection topologies.
What is the thermal resistance and how does it affect SMB10J17A-E3/5B's surge performance?
The SMB10J17A-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 determines how effectively heat dissipates during repetitive surges: lower RθJA allows higher duty cycles without thermal runaway. At 1000 W peak power, junction temperature rise is ~72 °C per pulse - acceptable within the +150 °C max rating if pulses are spaced adequately. PCB layout must adhere to the recommended pad dimensions to achieve this RθJA; reduced copper area increases thermal impedance and risks premature failure. The SMB10J17A-E3/5B's RθJA is validated per JEDEC standards and documented in Vishay's datasheet.
