Product details
Overview
SMB10J17AHE3_A/H 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 17 V stand-off voltage (VWM), 1000 W peak pulse power rating (10/1000 µs), clamping voltage of 27.6 V at 36.2 A peak surge current, and AEC-Q101 qualification for automotive electronics.
For engineers reviewing the SMB10J17AHE3_A/H datasheet, SMB10J17AHE3_A/H pinout, SMB10J17AHE3_A/H application, or SMB10J17AHE3_A/H equivalent, this device is selected for robust overvoltage protection in automotive ECUs, industrial sensor interfaces, and 12 V/24 V power supply inputs where low clamping voltage, fast response (<1 ns), and MSL Level 1 reflow compatibility are critical.
Technical Context
This TVS diode operates as a silicon avalanche clamp, triggered when reverse voltage exceeds its breakdown threshold (18.9–20.9 V at 1 mA). Its glass-passivated junction ensures stable leakage (<1 µA at 17 V) and long-term reliability under repetitive surge stress.
Thermal performance is defined by RθJA = 72 °C/W (on 5.0 mm × 5.0 mm copper pads) and maximum junction temperature of 150 °C. The device sustains 100 A non-repetitive forward surge (8.3 ms half-sine) and meets J-STD-020 MSL Level 1 with 260 °C peak reflow profile.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 17 V - Maximum continuous reverse operating voltage before clamping begins; sets safe margin below system rail (e.g., 12 V or 24 V nominal). |
| VBR (min/max) | 18.9 V / 20.9 V at 1 mA - Confirmed breakdown range ensures reliable turn-on without premature conduction during normal operation. |
| VC @ IPPM | 27.6 V at 36.2 A - Clamping voltage limits downstream IC stress during 10/1000 µs transients (e.g., ISO 7637-2 Pulse 1/2a/5a). |
| PPPM | 1000 W - Peak pulse power handling capability enables protection against high-energy surges like load dump (automotive) or inductive switching. |
| IFSM | 100 A - Forward surge rating supports robustness against accidental polarity reversal or high-current fault conditions. |
| TJ max | 150 °C - Enables operation in under-hood automotive environments and thermally constrained industrial enclosures. |

Use Value: Delivers precise clamping at 27.6 V with minimal let-through energy, reducing need for oversized secondary protection components. |
Use Scenario: Hardening 5 V USB power input or barrel-jack DC input of smart home hubs against user-induced ESD and hot-plug transients. IC Role / Device Role / Timing Role: Unidirectional TVS connected between VBUS and GND, rated for ±15 kV contact ESD (IEC 61000-4-2) per AEC-Q101 stress testing. Use Value: Survives repeated 8 kV contact / 15 kV air ESD events without parameter shift, ensuring field reliability across consumer lifecycle. |
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 SMB package, 17 V VWM, but rated for 600 W PPPM (vs. 1000 W) and not AEC-Q101 qualified. | Limited to commercial-grade industrial or consumer use; insufficient for automotive load dump requirements. | Select only if cost-sensitive and surge energy is ≤600 W; verify thermal derating for ambient >85 °C. |
| 1.5SMC17AHE3_A/H | Higher-power SMC package (1500 W), same 17 V VWM, AEC-Q101 qualified, but 2.5× larger footprint and higher RθJA (50 °C/W). | Better suited for high-energy transients where board space allows; less optimal for dense automotive modules. | Choose when system-level surge tests exceed 1000 W or when extended thermal margin is required beyond SMB10J17AHE3_A/H's 72 °C/W. |
Compared with SMBJ17A-E3/52 and 1.5SMC17AHE3_A/H, SMB10J17AHE3_A/H uniquely balances AEC-Q101 compliance, 1000 W surge capacity, and compact SMB footprint-making it optimal for space-constrained automotive modules requiring validated reliability without layout redesign.

FAQ
What is the clamping voltage of SMB10J17AHE3_A/H at its rated peak pulse current?
The SMB10J17AHE3_A/H has a maximum clamping voltage (VC) of 27.6 V when subjected to its peak pulse current (IPPM) of 36.2 A under the standardized 10/1000 µs waveform. This value is measured and guaranteed per the Vishay datasheet (Document Number: 88422, Rev. 09-Jan-2024), and defines the upper voltage limit imposed on protected circuitry during surge events. Maintaining VC ≤27.6 V ensures compatibility with 3.3 V, 5 V, and 12 V logic and power stages downstream of SMB10J17AHE3_A/H.
Is SMB10J17AHE3_A/H suitable for automotive applications?
Yes, SMB10J17AHE3_A/H is explicitly AEC-Q101 qualified, as confirmed in the Vishay datasheet (Section "MECHANICAL DATA" and ordering code suffix HE3). It undergoes stress testing for high-temperature operating life, temperature cycling, unbiased HAST, and ESD per AEC-Q101 Rev D. This makes SMB10J17AHE3_A/H suitable for under-hood and cabin automotive applications including body control modules, lighting drivers, and ADAS sensor power inputs-provided layout follows recommended pad dimensions and thermal relief guidelines.
What does the "HE3" suffix in SMB10J17AHE3_A/H indicate?
The "HE3" suffix in SMB10J17AHE3_A/H denotes RoHS-compliant construction with AEC-Q101 qualification, per Vishay's ordering nomenclature. "H" indicates the AEC-Q101 grade, "E3" specifies RoHS-compliant matte tin plating and halogen-free molding compound. The "_A/H" ending reflects the revision code (A) and packaging variant (H = 7″ tape and reel, 750 pcs). This distinguishes SMB10J17AHE3_A/H from commercial-grade variants like SMB10J17A-E3/52, which lack automotive qualification.
How does SMB10J17AHE3_A/H compare to bidirectional TVS diodes with the same VWM?
SMB10J17AHE3_A/H is unidirectional and optimized for DC rail protection where polarity is fixed (e.g., +12 V to GND). In contrast, bidirectional variants like SMB8J17CAHE3_A/H have symmetric breakdown in both directions and are used on AC or floating signal lines (e.g., RS-485, CAN). SMB10J17AHE3_A/H offers higher peak pulse power (1000 W vs. 800 W for SMB8J17CA) and lower clamping voltage in the forward direction, making it more effective for single-polarity surge suppression in automotive and industrial power domains.
What is the maximum operating temperature for SMB10J17AHE3_A/H?
The SMB10J17AHE3_A/H has a specified operating junction temperature range of –55 °C to +150 °C, with storage temperature matching this span. Its thermal resistance (RθJA) is 72 °C/W when mounted on 5.0 mm × 5.0 mm copper pads per terminal. At ambient temperatures up to 105 °C, SMB10J17AHE3_A/H maintains full surge capability provided PCB layout adheres to Vishay's recommended pad dimensions and thermal vias are used for enhanced heat dissipation in high-power-density designs.
