Product details
Overview
SMB10J15AHE3_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 with 15 V standoff voltage (VWM), 16.7–18.5 V breakdown range (VBR), and 1000 W peak pulse power (10/1000 µs). It clamps transients to ≤24.4 V at 41 A IPPM and is AEC-Q101 qualified for automotive electronics protection.
For engineers reviewing the SMB10J15AHE3_A/I datasheet, SMB10J15AHE3_A/I pinout, SMB10J15AHE3_A/I application, or SMB10J15AHE3_A/I equivalent, this device is selected for robust ESD/surge immunity in power rails and signal lines where low clamping voltage, fast response (<1 ns), and automotive-grade reliability are required.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector: under normal conditions it presents <1 µA leakage at 15 V; during transients exceeding VBR, it avalanches to clamp voltage at ≤24.4 V while dissipating up to 1000 W. Its glass-passivated junction ensures stable breakdown and low incremental surge resistance.
Designed for surface-mount automation, it meets MSL level 1 (260 °C reflow peak), JESD201 Class 2 whisker resistance, and UL 94 V-0 flammability. The matte tin-plated leads comply with J-STD-002 and JESD22-B102 solderability standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| VBR min/max | 16.7 V / 18.5 V at 1 mA - guaranteed avalanche initiation window for predictable clamping onset |
| VC @ IPPM | 24.4 V at 41 A - clamping voltage limiting downstream circuit stress during 10/1000 µs surge |
| PPPM | 1000 W - peak transient energy absorption capability per single 10/1000 µs waveform |
| ID @ VWM | ≤1.0 µA - ultra-low leakage preserving signal integrity and power efficiency in standby |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ15AHE3_A/I | Same VWM (15 V), identical SMB package, but rated for 600 W PPPM (vs. 1000 W) | Limited to lower-energy transients; not suitable for ISO 7637-2 Pulse 5a load dump | Select SMB10J15AHE3_A/I when >800 W surge handling is required; SMBJ15AHE3_A/I suffices for IEC 61000-4-2 ESD-only designs |
| SMCJ15AHE3_A/I | Same VWM and VBR, but in larger SMC (DO-214AB) package with 1500 W PPPM rating | Higher power handling but 30% larger footprint; requires PCB layout change | Choose SMB10J15AHE3_A/I for space-constrained automotive modules; SMCJ15AHE3_A/I where ultimate surge margin justifies added area |

FAQ
What is the clamping voltage of SMB10J15AHE3_A/I at its rated peak pulse current?
The SMB10J15AHE3_A/I clamps to a maximum of 24.4 V when subjected to its specified peak pulse current of 41 A under the standardized 10/1000 µs waveform. This value is measured at the device terminals and reflects worst-case voltage seen by downstream circuitry during surge events, enabling accurate system-level overvoltage margin analysis.
Is SMB10J15AHE3_A/I suitable for automotive applications?
Yes, SMB10J15AHE3_A/I is AEC-Q101 qualified and explicitly designated for automotive use via its HE3 suffix. It has passed stress tests including high-temperature reverse bias, temperature cycling, and ESD per JESD22, making it appropriate for engine control units, body electronics, and ADAS sensor modules where reliability under thermal and electrical stress is critical.
What does the "HE3" suffix indicate in SMB10J15AHE3_A/I?
The "HE3" suffix in SMB10J15AHE3_A/I denotes RoHS-compliant construction with AEC-Q101 qualification, distinguishing it from commercial-grade E3 variants. The "H" indicates automotive qualification, "E3" confirms lead-free and RoHS compliance, and "_A/I" specifies packaging: "A" = revision code, "I" = 13-inch tape-and-reel (3200 units).
How does SMB10J15AHE3_A/I differ from bidirectional TVS diodes with similar voltage ratings?
SMB10J15AHE3_A/I is unidirectional and conducts only during positive overvoltage relative to ground, making it ideal for DC power rail protection. Bidirectional variants like SMB8J15CA offer symmetrical clamping for AC lines or floating signals but exhibit lower PPPM (800 W vs. 1000 W) and higher capacitance-SMB10J15AHE3_A/I provides superior DC surge margin with minimal leakage impact.
What is the thermal resistance of SMB10J15AHE3_A/I, and how does it affect power dissipation?
SMB10J15AHE3_A/I has a typical junction-to-ambient thermal resistance (RθJA) of 72 °C/W when mounted on 0.2" × 0.2" copper pads. This value determines steady-state temperature rise under continuous power; however, since TVS operation is transient, RθJA primarily influences recovery time between surges and long-term reliability under repeated stress-not steady-state dissipation.
