Product details
Overview
SMB10J15AHE3_B/H 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 voltage (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_B/H datasheet, SMB10J15AHE3_B/H pinout, SMB10J15AHE3_B/H application, or SMB10J15AHE3_B/H equivalent, key selection criteria include unidirectional polarity, 1.0 µA max reverse leakage at VWM, MSL Level 1 moisture sensitivity, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode employs a glass-passivated silicon junction optimized for fast response (<1 ns) to ESD and lightning-induced transients. Its low incremental surge resistance ensures stable clamping under repetitive 10/1000 µs surges up to 41 A, while thermal resistance RθJA = 72 °C/W supports operation at TJ up to +150 °C.
The device meets ANSI/IEEE C62.35 standards for transient suppression and is rated for automotive-grade reliability per AEC-Q101. Polarity is marked by a cathode band; no marking indicates bidirectional variants - but SMB10J15AHE3_B/H is explicitly unidirectional per ordering code "A" and electrical table entry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 15 V - maximum continuous reverse operating voltage before clamping begins |
| VBR min/max | 16.7 V / 18.5 V at 1.0 mA - guaranteed breakdown threshold range for reliable turn-on margin |
| VC @ IPPM | 24.4 V at 41 A - clamped voltage during 10/1000 µs surge, defining protected circuit stress level |
| PPPM | 1000 W - peak transient energy handling capacity under standardized waveform |
| ID @ VWM | ≤1.0 µA - ultra-low leakage preserves signal integrity in high-impedance sensor or data lines |
| TJ max | +150 °C - enables deployment in under-hood automotive environments without derating |
| MSL Level | Level 1 (260 °C peak reflow) - supports standard lead-free SMT assembly without baking |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. Cathode indicated by color band.

Applications
| Automotive Power Line Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V supply rails in body control modules against load dump and alternator transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between battery rail and downstream DC/DC converter input. Use Value: Clamps 1000 W surges to ≤24.4 V, preventing overvoltage damage to LDOs and microcontrollers without sacrificing response speed. | Use Scenario: Shielding analog output lines (e.g., 4–20 mA current loops) in factory automation sensors from ESD and inductive switching noise. IC Role / Device Role / Timing Role: TVS connected across signal and ground near connector entry point. Use Value: 1.0 µA leakage at 15 V VWM avoids loading high-impedance sensor outputs; 24.4 V VC limits fault voltage seen by ADC front-end. |
| Automotive CAN Bus Node Protection | Consumer Power Adapter Input Stage |
Use Scenario: Safeguarding CAN transceivers (e.g., TJA1042) on vehicle infotainment networks exposed to ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Unidirectional TVS on VCC line feeding transceiver, with cathode grounded. Use Value: Fast <1 ns response captures edge-triggered transients before they propagate; AEC-Q101 compliance ensures lifetime reliability in vibration-prone environments. | Use Scenario: Input-stage surge suppression in USB-C PD adapters subjected to AC line surges and hot-plug events. IC Role / Device Role / Timing Role: Primary TVS on secondary-side 15 V bus after isolation transformer and rectifier. Use Value: 1000 W rating handles repeated 10/1000 µs surges per IEC 61000-4-5; RoHS-compliant HE3 suffix meets global regulatory requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ15A-E3/52 | Same VWM/VBR/PPPM specs; commercial-grade (non-AEC-Q101); E3 suffix only | Lacks automotive qualification; suitable for industrial/commercial power supplies | Select when AEC-Q101 is not required and cost optimization is prioritized |
| 1.5SMC15A | Higher package thermal resistance (RθJA ≈ 110 °C/W); same 15 V VWM but lower IPPM (38.5 A vs. 41 A) | Lower surge current handling; less suitable for high-repetition automotive transients | Choose only if SMB footprint is unavailable and SMC (DO-214AB) layout accommodates larger size |
Compared with SMBJ15A-E3/52 and 1.5SMC15A, SMB10J15AHE3_B/H delivers automotive-grade reliability with identical electrical performance in a compact SMB package, enabling drop-in replacement where AEC-Q101 compliance and MSL Level 1 assembly are mandatory.

FAQ
What is the clamping voltage of SMB10J15AHE3_B/H at its rated peak pulse current?
The SMB10J15AHE3_B/H has a maximum clamping voltage (VC) of 24.4 V when subjected to its peak pulse current (IPPM) of 41 A under a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuits during surge events. The SMB10J15AHE3_B/H maintains this clamping performance across its specified operating temperature range.
Is SMB10J15AHE3_B/H suitable for automotive applications?
Yes, SMB10J15AHE3_B/H is AEC-Q101 qualified and carries the HE3 suffix indicating RoHS-compliance and automotive-grade reliability. It is rated for junction temperatures up to +150 °C and meets MSL Level 1 for lead-free reflow, making it appropriate for under-hood and cabin-mounted automotive electronics including body control modules and sensor interfaces.
What does the "HE3_B/H" suffix in SMB10J15AHE3_B/H indicate?
The "HE3" denotes RoHS-compliant and AEC-Q101 qualified construction; "B/H" specifies packaging: 7-inch tape-and-reel with 750 units per reel (H = reel size code). This full suffix confirms the part meets automotive quality requirements and ships in standard SMT-compatible format - distinct from commercial-grade E3 or halogen-free HM3 variants.
How does SMB10J15AHE3_B/H differ from SMBJ15A?
SMB10J15AHE3_B/H and SMBJ15A share identical electrical parameters (VWM = 15 V, VBR = 16.7–18.5 V, PPPM = 1000 W), but SMB10J15AHE3_B/H is AEC-Q101 qualified and rated for automotive use, whereas SMBJ15A is commercial-grade. The "HE3" suffix also guarantees halogen-free exemption status and traceable lot control per automotive supply chain requirements.
What is the reverse leakage current of SMB10J15AHE3_B/H at its standoff voltage?
The SMB10J15AHE3_B/H exhibits a maximum reverse leakage current (ID) of 1.0 µA at its 15 V standoff voltage (VWM), measured at TA = 25 °C. This ultra-low leakage preserves signal integrity in high-impedance circuits such as sensor bias networks or precision analog inputs, and remains stable across its -55 °C to +150 °C operating junction temperature range.
