Product details
Overview
SMB10J15AHE3_B/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 15 V stand-off voltage (VWM), 24.4 V maximum clamping voltage at 41.0 A peak pulse current (10/1000 µs), and 1000 W peak pulse power rating. Used to protect automotive-grade MOSFETs, sensor interfaces, and microcontroller I/O against inductive switching transients.
For engineers reviewing the SMB10J15AHE3_B/I datasheet, SMB10J15AHE3_B/I pinout, SMB10J15AHE3_B/I application, or SMB10J15AHE3_B/I equivalent, this AEC-Q101 qualified TVS offers verified clamping performance, low incremental surge resistance, and MSL Level 1 reflow compatibility - critical for automotive electronics design validation and ESD/surge robustness testing.
Technical Context
This device operates as a unidirectional avalanche diode with glass-passivated junction, enabling sub-nanosecond response to transients. Its breakdown voltage range is 16.7–18.5 V at 1 mA test current, and it maintains stable clamping up to 150 °C junction temperature.
The SMB10J15AHE3_B/I is rated for 100 A non-repetitive forward surge current (8.3 ms half-sine), supports automated SMT placement, and meets J-STD-020 reflow profile with 260 °C peak temperature. Polarity is marked by cathode band; terminals are matte tin plated and whisker-resistant per JESD 201 Class 2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 15 V - Maximum continuous reverse voltage before significant leakage; defines operating margin below clamping threshold. |
| VBR (Breakdown Voltage) | 16.7–18.5 V at 1 mA - Ensures reliable turn-on during overvoltage events without premature conduction. |
| VC (Clamping Voltage) | 24.4 V at 41.0 A (10/1000 µs) - Limits downstream voltage stress to safe levels for protected ICs. |
| PPPM (Peak Pulse Power) | 1000 W - Sustains high-energy surges typical of ISO 7637-2 Load Dump or IEC 61000-4-5 Level 4. |
| ID (Reverse Leakage) | 1.0 µA max at 15 V - Minimizes standby power loss and avoids false triggering in low-power circuits. |
| TJ max | 150 °C - Enables operation in under-hood automotive environments and industrial enclosures. |
| AEC-Q101 Qualified | Yes - Validated for automotive electronic modules requiring reliability across temperature cycling, humidity, and vibration. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with molded UL 94 V-0 compound. Cathode indicated by color band on one end; anode on opposite end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient current sink | Connected to protected line; conducts surge current to ground when voltage exceeds VBR. |

Applications
| Automotive Sensor Interface Protection | Industrial Motor Drive I/O Protection |
|---|---|
Use Scenario: Protecting CAN/LIN transceiver inputs and analog sensor outputs (e.g., pressure, temperature) from load dump and inductive kickback in 12 V vehicle systems. IC Role / Device Role / Timing Role: Unidirectional TVS placed between signal line and chassis ground to clamp transients before they reach the transceiver's ESD diodes. Use Value: Prevents latch-up or permanent damage to automotive-grade transceivers by limiting voltage to ≤24.4 V during 1000 W surges. |
Use Scenario: Safeguarding PLC digital input modules connected to solenoids, relays, and contactors subject to repetitive inductive switching spikes. IC Role / Device Role / Timing Role: Standoff-clamp TVS on 24 V DC input lines, absorbing energy from >100 V flyback voltages generated during coil de-energization. Use Value: Extends module lifetime by eliminating cumulative degradation of optocoupler input stages and front-end protection networks. |
| Consumer Power Adapter Output Protection | Telecom DC Power Feeding Line Protection |
Use Scenario: Secondary-side surge suppression on 5–19 V USB PD and laptop adapter outputs exposed to accidental short-circuits and hot-plug transients. IC Role / Device Role / Timing Role: Fast-response unidirectional clamp between VOUT and GND, activated within <1 ns to limit output overshoot during fault recovery. Use Value: Maintains compliance with IEC 62368-1 transient immunity requirements while preserving tight output regulation. |
Use Scenario: Protecting PoE-powered equipment (e.g., IP cameras, wireless APs) from surges induced on 48 V DC feeding lines due to lightning coupling or ground potential differences. IC Role / Device Role / Timing Role: Primary-line TVS on PSE-side or PD-side DC bus, coordinated with upstream fuses to clear faults without damaging IEEE 802.3af/at circuitry. Use Value: Enables robust 48 V DC line protection with 1000 W surge capacity and minimal capacitance impact on high-speed data integrity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ15AHE3_A/H | Same VWM (15 V), identical SMB package, but lower PPPM (600 W) and higher VC (24.4 V @ 24.7 A). | Limited to lower-energy transients (e.g., IEC 61000-4-2 ESD only); not suitable for ISO 7637-2 Load Dump. | Select SMB10J15AHE3_B/I when 1000 W surge handling is required; choose SMBJ15AHE3_A/H only for space-constrained cost-sensitive consumer designs. |
| SMCJ15AHE3_A/H | Same electrical specs but larger SMC (DO-214AB) package; 1500 W PPPM rating and lower Rsurge. | Better thermal dissipation for repeated surges; requires larger PCB footprint and different pad layout. | Choose SMB10J15AHE3_B/I for compact automotive modules where board area is constrained; use SMCJ15AHE3_A/H for industrial power supplies needing higher surge endurance. |
Compared with SMBJ15AHE3_A/H and SMCJ15AHE3_A/H, SMB10J15AHE3_B/I delivers optimal balance of 1000 W surge capability, SMB footprint, and AEC-Q101 qualification - making it the preferred choice for automotive and space-limited industrial TVS deployments.

FAQ
What is the clamping voltage of SMB10J15AHE3_B/I at its rated peak pulse current?
The SMB10J15AHE3_B/I has a maximum clamping voltage (VC) of 24.4 V when subjected to a 10/1000 µs waveform peak pulse current of 41.0 A. This value is measured under standardized test conditions and ensures predictable voltage limiting during surge events. The SMB10J15AHE3_B/I maintains this clamping performance across its full operating temperature range up to 150 °C junction temperature.
Is SMB10J15AHE3_B/I suitable for automotive applications?
Yes, SMB10J15AHE3_B/I is AEC-Q101 qualified and explicitly designated for automotive use with the "HE3" suffix. It meets stringent requirements for temperature cycling, mechanical shock, and humidity resistance. The SMB10J15AHE3_B/I is commonly deployed in body control modules, sensor interfaces, and infotainment power rails where ISO 7637-2 and ISO 16750-2 compliance is mandatory.
What does the "B/I" suffix mean in SMB10J15AHE3_B/I?
The "B/I" suffix in SMB10J15AHE3_B/I indicates packaging configuration: "B" denotes the base revision level, and "I" specifies 13-inch diameter plastic tape-and-reel delivery containing 3200 units. This format is optimized for high-volume SMT assembly lines and aligns with Vishay's standard ordering code structure for AEC-Q101 qualified parts.
How does SMB10J15AHE3_B/I differ from bidirectional TVS diodes like SMB8J15CAHE3_B/I?
The SMB10J15AHE3_B/I is unidirectional and intended for DC line protection with polarity-sensitive placement (cathode toward protected line), whereas SMB8J15CAHE3_B/I is bidirectional and symmetric for AC or floating-line applications. The SMB10J15AHE3_B/I offers higher peak pulse power (1000 W vs. 800 W) and is optimized for automotive DC systems, while the bidirectional variant supports telecom or audio signal line protection.
What is the thermal resistance of SMB10J15AHE3_B/I, and how does it affect PCB layout?
The SMB10J15AHE3_B/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. To maintain safe junction temperatures during repeated surges, PCB layout must replicate this minimum pad area and ensure adequate copper pour. Reducing pad size increases thermal impedance and risks exceeding the 150 °C TJ max rating during high-duty-cycle transients.
