Product details
Overview
SMB10J17AHE3_A/I 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 SMB10J17AHE3_A/I datasheet, SMB10J17AHE3_A/I pinout, SMB10J17AHE3_A/I application, or SMB10J17AHE3_A/I equivalent, key selection criteria include AEC-Q101 qualification, low clamping ratio (VC/VBR ≈ 1.45), unidirectional polarity with cathode band marking, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a clamping-type overvoltage protector, leveraging an avalanche breakdown mechanism to limit transient voltages before they reach downstream ICs or MOSFETs. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low leakage (<1 µA at VWM), while its thermal resistance (RθJA = 72 °C/W) supports operation up to +150 °C junction temperature.
The device meets J-STD-020 MSL Level 1 (peak reflow ≤ 260 °C) and is qualified to AEC-Q101 for automotive use. Its fast response time (<1 ns) and low incremental surge resistance enable effective suppression of ESD, lightning-induced surges, and inductive switching transients in DC power rails and sensor signal paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 17 V - maximum continuous reverse operating voltage before significant leakage; defines safe DC bias margin for protected line |
| VBR (min/max) | 18.9 V / 20.9 V at 1 mA - tight breakdown window ensures predictable turn-on during transients without false triggering |
| VC @ IPPM | 27.6 V at 36.2 A - clamping voltage under 1000 W 10/1000 µs surge; limits stress on downstream 24 V-rated components |
| PPPM | 1000 W - peak pulse power handling capacity; enables robust protection against ISO 7637-2 Pulse 1/2a/5a in automotive systems |
| IFSM | 100 A - non-repetitive forward surge current rating; supports single-event load dump survival when used in series with fuse or current limiter |
| TJ max | +150 °C - maximum junction temperature; allows operation in under-hood automotive environments and industrial enclosures |
| Package | SMB (DO-214AA) - surface-mount outline with 2.20 mm × 3.94 mm footprint; compatible with standard 0.2" × 0.2" copper pad layout per datasheet fig. 6 |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ17A-E3/52 | Same VWM (17 V), VBR (18.9–20.9 V), and PPPM (1000 W); RoHS-compliant commercial grade (non-AEC-Q101) | Lacks automotive qualification; suitable for industrial/commercial designs where AEC-Q101 is not mandated | Select when cost sensitivity outweighs automotive qualification requirement and environmental stress testing is less stringent |
| 1.5SMC17A | Same electrical specs but in larger SMC (DO-214AB) package; RθJA = 40 °C/W vs. 72 °C/W; higher IPPM (42.2 A) | Better thermal performance and surge margin; requires larger PCB footprint (7.11 mm × 6.22 mm vs. SMB's 3.94 mm × 2.20 mm) | Choose when board space permits and higher thermal headroom or legacy SMC footprint compatibility is needed |
Compared with SMBJ17A-E3/52, SMB10J17AHE3_A/I adds AEC-Q101 qualification and tighter manufacturing controls for automotive use; compared with 1.5SMC17A, it trades thermal performance and surge margin for compact SMB footprint and lower profile - critical for space-constrained modules.

FAQ
What is the clamping voltage of SMB10J17AHE3_A/I at its rated peak pulse current?
The SMB10J17AHE3_A/I has a maximum clamping voltage (VC) of 27.6 V at its specified peak pulse current (IPPM) of 36.2 A, measured under the standard 10/1000 µs double-exponential surge waveform. This value is confirmed in the "UNIDIRECTIONAL" table on page 2 of Vishay document 88422 and defines the upper voltage limit imposed on protected circuits during worst-case transient events.
Is SMB10J17AHE3_A/I suitable for automotive applications?
Yes, SMB10J17AHE3_A/I is explicitly AEC-Q101 qualified, as noted in the "FEATURES" section and "ORDERING INFORMATION" of Vishay document 88422. The "HE3" suffix denotes RoHS-compliant and AEC-Q101 qualified construction, making SMB10J17AHE3_A/I appropriate for under-hood and cabin electronics including body control modules, sensor interfaces, and infotainment power supplies.
What does the "_A/I" suffix mean in SMB10J17AHE3_A/I?
The "_A/I" suffix in SMB10J17AHE3_A/I indicates the revision code ("A") and tape-and-reel packaging option ("I" = 13-inch diameter reel, 3200 units per reel), per the "ORDERING INFORMATION" table on page 3 of Vishay document 88422. The "HE3" portion confirms RoHS-compliance and AEC-Q101 qualification, distinguishing it from commercial-grade variants like "E3".
How does SMB10J17AHE3_A/I differ from bidirectional variants like SMB8J17CA?
SMB10J17AHE3_A/I is unidirectional with cathode marking and conducts only during positive transients relative to ground, whereas SMB8J17CA is bidirectional and protects against both polarities. SMB10J17AHE3_A/I offers higher peak pulse power (1000 W vs. 800 W) and higher IPPM (36.2 A vs. 29.0 A), making it preferable for asymmetric DC rail protection where polarity is fixed and surge energy is higher.
What is the thermal resistance of SMB10J17AHE3_A/I, and how does it affect layout?
SMB10J17AHE3_A/I 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, as specified in the "THERMAL CHARACTERISTICS" table. To maintain safe junction temperatures under repeated surges, PCB layout must provide minimum recommended pad area and avoid excessive trace length or narrow traces between SMB10J17AHE3_A/I terminals and solid copper planes.
