Product details
Overview
SMB10J24AHE3_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 DC power rails and signal lines. It features a 24 V stand-off voltage (VWM), 26.7–29.5 V breakdown voltage (VBR), 38.9 V clamping voltage (VC) at 25.7 A peak pulse current (IPPM), and 1000 W peak pulse power (PPPM) with 10/1000 µs waveform - used in automotive power supply input stages and industrial sensor interface protection.
For engineers reviewing the SMB10J24AHE3_B/I datasheet, SMB10J24AHE3_B/I pinout, SMB10J24AHE3_B/I application, or SMB10J24AHE3_B/I equivalent, key selection criteria include AEC-Q101 qualification, unidirectional polarity with cathode band marking, low incremental surge resistance, and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
This TVS diode operates as a voltage-clamped crowbar device during transients, leveraging a glass-passivated silicon junction to achieve sub-nanosecond response time and stable clamping under repetitive surges. Its thermal resistance (RθJA = 72 °C/W) and junction temperature limit (TJ max = 150 °C) support sustained operation in under-hood automotive environments.
The SMB10J24AHE3_B/I complies with ANSI/IEEE C62.35 surge standards and meets J-STD-020 MSL Level 1 (260 °C peak reflow). Its matte tin-plated leads are solderable per J-STD-002 and JESD 22-B102, and it passes JESD 201 Class 2 whisker testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 24 V - maximum continuous reverse operating voltage before clamping begins; defines safe DC rail margin for 24 V systems. |
| VBR (min/max) | 26.7 V / 29.5 V at 1.0 mA - guaranteed breakdown threshold ensures reliable turn-on above nominal rail. |
| VC @ IPPM | 38.9 V at 25.7 A - clamping voltage limits downstream IC stress during IEC 61000-4-5 10/1000 µs surge events. |
| PPPM | 1000 W - peak pulse power handling capacity supports high-energy transients in automotive load-dump scenarios. |
| IFSM | 100 A - non-repetitive forward surge rating enables robustness against accidental reverse-bias faults or miswiring. |
| TJ max | 150 °C - extended junction temperature range allows deployment in engine control units and power distribution modules. |
| AEC-Q101 | Qualified - certified for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC standard. |
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.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point during clamping | Connected to protected line (e.g., 24 V rail); conducts surge current toward ground when V > VBR. |
| Cathode | Reverse-biased terminal; marked with band | Connected to system ground; establishes unidirectional clamping direction and defines polarity-sensitive placement. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable VBR over lifetime and improved moisture resistance vs. epoxy-passivated alternatives. |
| AEC-Q101 qualification | Validates suitability for automotive powertrain and body electronics without additional qualification effort. |
| MSL Level 1 rating | Allows unlimited floor life and single-reflow processing at 260 °C peak, simplifying SMT manufacturing flow. |
| Low RINC (incremental surge resistance) | Minimizes VC overshoot during fast-rising transients, improving protection margin for sensitive 3.3 V/5 V logic. |
| Matte tin plating | Ensures reliable solder wetting and intermetallic formation per J-STD-002, reducing voiding risk in high-volume assembly. |
Applications
| Automotive Power Input Protection | Industrial Sensor Signal Line Protection |
|---|---|
Use Scenario: Protecting 24 V battery-fed ECUs from load dump and jump-start transients per ISO 7637-2 Pulse 5a. IC Role / Device Role / Timing Role: Primary clamping element placed between input rail and ground, absorbing up to 1000 W surges. Use Value: Limits rail voltage to ≤38.9 V during 100 V/100 ms load dump, preventing damage to downstream DC-DC controllers and microcontrollers. |

Use Scenario: Suppressing back-EMF spikes from brushed DC motors in smart home appliances (e.g., washing machine drive circuits). IC Role / Device Role / Timing Role: Unidirectional clamp across motor terminals or H-bridge supply rails to divert inductive kickback. Use Value: Limits flyback voltage to 38.9 V, preventing MOSFET avalanche failure and eliminating need for snubber RC networks. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ24AHE3_A/H | Same VWM/VBR/VC specs; identical SMB package; differs only in revision code (A/H vs. B/I) and reel size (750 vs. 3200 pcs). | No functional difference; suitable for same PCB layouts and qualification records. | Select SMBJ24AHE3_A/H only if legacy BOM specifies revision A or smaller reel quantity is required. |
| 1.5SMC24AH | Higher PPPM (1500 W), larger SMC (DO-214AB) package (4.5 × 3.9 mm vs. 4.6 × 3.9 mm), 20% higher VC (47.1 V @ 31.9 A). | Requires PCB pad redesign; better suited for higher-energy surges but increases board area and thermal mass. | Choose 1.5SMC24AH only when 1000 W is insufficient and layout space permits larger footprint. |
Compared with SMBJ24AHE3_A/H, SMB10J24AHE3_B/I offers identical electrical performance with updated revision and larger reel packaging; versus 1.5SMC24AH, it trades peak power for compact SMB footprint and lower clamping voltage - critical for space-constrained 24 V automotive modules.

FAQ
What is the clamping voltage of SMB10J24AHE3_B/I at its rated peak pulse current?
The SMB10J24AHE3_B/I has a maximum clamping voltage (VC) of 38.9 V at 25.7 A peak pulse current (IPPM), measured under standardized 10/1000 µs waveform conditions. This value ensures downstream components see limited overvoltage during surge events, and it is guaranteed across the full operating temperature range per Vishay Document 88422.
Is SMB10J24AHE3_B/I qualified for automotive use?
Yes, SMB10J24AHE3_B/I is AEC-Q101 qualified, as confirmed in Vishay's official documentation (Document Number 88422, Revision 09-Jan-2024). The HE3 suffix explicitly denotes RoHS-compliant and AEC-Q101-qualified variants, making SMB10J24AHE3_B/I suitable for automotive powertrain, body, and chassis applications without additional qualification.
What does the "B/I" suffix mean in SMB10J24AHE3_B/I?
The "B/I" suffix in SMB10J24AHE3_B/I indicates revision level "B" and packaging format "I", where "I" denotes 13-inch diameter plastic tape and reel containing 3200 units. This matches Vishay's ordering convention in Document 88422, Table "ORDERING INFORMATION", confirming full traceability and compliance with JEDEC standards for SMT handling.
Can SMB10J24AHE3_B/I replace SMBJ24A in existing designs?
SMB10J24AHE3_B/I is functionally equivalent to SMBJ24A in electrical parameters (VWM = 24 V, VBR = 26.7–29.5 V, VC = 38.9 V) and shares the same SMB (DO-214AA) package outline and pinout. No PCB changes are required, though users should verify reel packaging and revision alignment with their manufacturing process controls.
What is the maximum operating temperature for SMB10J24AHE3_B/I?
The SMB10J24AHE3_B/I has a maximum junction temperature (TJ max) of +150 °C, as specified in the "MAXIMUM RATINGS" table of Vishay Document 88422. This rating supports continuous operation in under-hood automotive environments and high-ambient industrial enclosures, provided thermal design accounts for RθJA = 72 °C/W.
