Product details
Overview
SMB10J24AHE3/5B 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) at 1 mA, 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 - deployed in automotive power supply inputs and industrial sensor interfaces.
For engineers reviewing the SMB10J24AHE3/5B datasheet, SMB10J24AHE3/5B pinout, SMB10J24AHE3/5B application, or SMB10J24AHE3/5B 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 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a clamping device that remains non-conductive below 24 V and rapidly transitions to low-impedance conduction during transients exceeding its breakdown threshold. Its glass-passivated junction ensures stable VBR tolerance and long-term reliability under repetitive surge stress.
Designed per ANSI/IEEE C62.35 standards, SMB10J24AHE3/5B delivers sub-nanosecond response time and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak. Thermal resistance is 72 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead), enabling robust thermal management in compact layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 24 V - maximum continuous reverse operating voltage before leakage exceeds 1 µA; defines safe DC rail margin for 24 V systems. |
| VBR (min/max) | 26.7 V / 29.5 V at 1 mA - tight breakdown window ensures predictable turn-on without premature conduction. |
| VC @ IPPM | 38.9 V at 25.7 A - clamping voltage limits downstream IC stress during 1000 W surge events. |
| PPPM | 1000 W (10/1000 µs) - supports high-energy transients common in automotive load-dump and inductive switching. |
| IFSM | 100 A (8.3 ms half-sine) - withstands short-duration overcurrent surges without bond-wire failure. |
| TJ max | 150 °C - enables operation in under-hood automotive environments and industrial enclosures. |
| AEC-Q101 | Qualified - certified for automotive-grade reliability including temperature cycling, HTRB, and ESD testing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ24A-E3/52 | Same VWM/VBR/VC specs but commercial-grade (non-AEC-Q101), MSL Level 1, RoHS-compliant. | Lacks automotive qualification; suitable for industrial/commercial power supplies where AEC-Q101 not mandated. | Select when cost sensitivity outweighs automotive reliability requirements and lifecycle traceability is not required. |
| SMAJ24AHE3/A | Lower PPPM (400 W), smaller SMA package (DO-214AC), same VWM/VBR range and AEC-Q101 qualified. | Used where board space is constrained and surge energy is limited to ≤400 W (e.g., low-power sensor nodes). | Choose for space-constrained designs accepting reduced surge margin; verify thermal derating at 72 °C/W vs. 50 °C/W for SMA. |
Compared with SMBJ24A-E3/52 and SMAJ24AHE3/A, SMB10J24AHE3/5B uniquely combines AEC-Q101 qualification, 1000 W surge capacity, and SMB footprint - making it optimal for automotive 24 V systems requiring both high energy handling and automotive-grade validation.

FAQ
What is the clamping voltage of SMB10J24AHE3/5B at its rated peak pulse current?
The SMB10J24AHE3/5B has a maximum clamping voltage (VC) of 38.9 V at 25.7 A peak pulse current (IPPM), measured with a 10/1000 µs waveform. This value ensures protected circuits remain within safe voltage margins during high-energy transients. The SMB10J24AHE3/5B achieves this clamping performance while maintaining low incremental surge resistance, critical for effective energy diversion in automotive and industrial applications.
Is SMB10J24AHE3/5B suitable for automotive applications?
Yes, SMB10J24AHE3/5B is AEC-Q101 qualified and explicitly designated for automotive use with the "HE3" suffix indicating RoHS-compliant and AEC-Q101 qualified construction. It meets requirements for under-hood and body electronics, including thermal cycling, humidity testing, and surge endurance. The SMB10J24AHE3/5B is commonly used in 24 V vehicle subsystems such as lighting controllers, ADAS sensor hubs, and power distribution modules.
What does the "5B" in SMB10J24AHE3/5B indicate?
The "5B" suffix denotes the packaging configuration: 13-inch diameter plastic tape-and-reel with 3200 units per reel. This format supports high-volume SMT assembly and is compatible with standard pick-and-place equipment. The base part SMB10J24AHE3 is identical electrically and mechanically; only the packaging differs from alternatives like "52" (7-inch reel, 750 units). The SMB10J24AHE3/5B ensures consistent feeding and placement reliability in automated manufacturing lines.
How does SMB10J24AHE3/5B differ from bidirectional TVS diodes like SMB8J24CA?
SMB10J24AHE3/5B is unidirectional and optimized for DC rail protection with asymmetric conduction (cathode-marked), whereas SMB8J24CA is bidirectional and suited for AC or dual-polarity signal lines. SMB10J24AHE3/5B offers higher peak pulse power (1000 W vs. 800 W) and higher IFSM (100 A vs. N/A for bidirectional), reflecting its DC-focused design. The SMB10J24AHE3/5B also features tighter VBR tolerance and lower leakage at VWM, enhancing stability in always-on 24 V systems.
What is the thermal resistance of SMB10J24AHE3/5B, and how does it affect layout?
SMB10J24AHE3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 72 °C/W and junction-to-lead (RθJL) of 20 °C/W. To maintain safe operation at full 1000 W surge rating, PCB layout must use minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, as specified in the datasheet. Insufficient copper area causes excessive junction temperature rise, reducing surge endurance and long-term reliability. The SMB10J24AHE3/5B thermal performance is validated only with this pad layout.
