Product details
Overview
SMB10J24AHE3_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 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_A/I datasheet, SMB10J24AHE3_A/I pinout, SMB10J24AHE3_A/I application, or SMB10J24AHE3_A/I equivalent, this device is selected for AEC-Q101-qualified 24 V system protection where low clamping voltage, fast response (<1 ns), and MSL Level 1 reflow compatibility are critical design requirements.
Technical Context
This unidirectional TVS diode operates as a shunt-clamping protector: under normal conditions it presents high impedance (>1 µA leakage at 24 V), then rapidly avalanches to limit transient overvoltages above its breakdown threshold. Its glass-passivated junction ensures stable VBR tolerance and long-term reliability under repetitive surge stress.
Thermal performance is defined by RθJA = 72 °C/W and RθJL = 20 °C/W, enabling effective heat dissipation when mounted on 5.0 mm × 5.0 mm copper pads per terminal. The device supports 100 A non-repetitive forward surge current (IFSM) and operates across -55 °C to +150 °C junction temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 24 V - maximum continuous reverse operating voltage before significant leakage; defines safe DC rail voltage margin. |
| VBR min/max | 26.7 V / 29.5 V at 1 mA - tight breakdown window ensures predictable turn-on during transients. |
| 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) - energy-handling capacity suitable for ISO 7637-2 Pulse 1/2a/5a automotive transients. |
| TJ max | +150 °C - enables operation in under-hood automotive environments and industrial enclosures. |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD. |
| Package | SMB (DO-214AA) - surface-mount footprint compatible with automated assembly; MSL Level 1 (260 °C peak). |
Pinout & Package
Two-terminal unidirectional TVS diode in SMB (DO-214AA) package. Cathode indicated by black band; anode is unmarked end. Mounting requires 5.0 mm × 5.0 mm copper pad per terminal for rated thermal and surge performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Surge current sink node | Connected to protected line; conducts avalanche current to ground during overvoltage events. |

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/I | Same SMB package, identical VWM/VBR/VC specs, but rated for 600 W PPPM (vs. 1000 W). | Limited to lower-energy transients (e.g., IEC 61000-4-2 ESD only); insufficient for ISO 7637-2 Pulse 5a. | Select SMB10J24AHE3_A/I when 1000 W surge handling is required; choose SMBJ24AHE3_A/I only for cost-sensitive, low-surge environments. |
| 1.5KE24A | Through-hole DO-201 package; same 24 V VWM, but higher VC = 38.9 V at lower IPPM = 25.7 A and 1500 W rating. | Not AEC-Q101 qualified; unsuitable for automotive; larger footprint limits high-density layouts. | Use 1.5KE24A only in legacy through-hole designs or non-automotive industrial equipment where AEC-Q101 is not mandated. |
Compared with SMBJ24AHE3_A/I and 1.5KE24A, SMB10J24AHE3_A/I uniquely delivers AEC-Q101 qualification, 1000 W surge capability in surface-mount SMB format, and verified thermal performance on standard 5 mm² pads - making it the optimal choice for next-generation automotive and industrial 24 V systems requiring both reliability and miniaturization.

FAQ
What is the clamping voltage of SMB10J24AHE3_A/I at its rated peak pulse current?
The SMB10J24AHE3_A/I has a maximum clamping voltage (VC) of 38.9 V when subjected to its rated peak pulse current (IPPM) of 25.7 A using a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 standards and ensures downstream circuitry remains within safe voltage limits during surge events. The SMB10J24AHE3_A/I achieves this clamping performance while maintaining low incremental surge resistance for efficient energy diversion.
Is SMB10J24AHE3_A/I qualified for automotive applications?
Yes, SMB10J24AHE3_A/I is AEC-Q101 qualified - explicitly stated in Vishay's documentation with suffix "HE3" denoting RoHS-compliant and AEC-Q101-qualified variants. It undergoes rigorous stress testing including temperature cycling, highly accelerated life testing (HALT), and ESD validation to meet automotive reliability requirements. The SMB10J24AHE3_A/I is routinely deployed in engine control modules, body control units, and ADAS sensor interfaces.
What is the thermal resistance of SMB10J24AHE3_A/I, and how does it affect PCB layout?
The SMB10J24AHE3_A/I has a typical junction-to-ambient thermal resistance (RθJA) of 72 °C/W and junction-to-lead (RθJL) of 20 °C/W when mounted on 5.0 mm × 5.0 mm copper pads per terminal. To achieve rated surge performance, PCB layout must provide these minimum pad sizes - undersized pads increase thermal impedance and reduce safe operating area during repetitive surges. The SMB10J24AHE3_A/I's thermal profile directly impacts sustained surge duty cycle capability.
How does SMB10J24AHE3_A/I differ from bidirectional TVS diodes like SMB8J24CA?
SMB10J24AHE3_A/I is unidirectional and optimized for DC power line protection where polarity is fixed; it offers 1000 W PPPM and 100 A IFSM. In contrast, SMB8J24CA is bidirectional with symmetrical breakdown, rated for 800 W PPPM and no IFSM rating. The SMB10J24AHE3_A/I provides superior surge handling on polarized rails and supports forward surge current - making it preferred for 24 V automotive supply inputs, whereas SMB8J24CA suits AC-coupled or dual-polarity signal lines.
What packaging and reel options are available for SMB10J24AHE3_A/I?
SMB10J24AHE3_A/I is supplied in 13-inch plastic tape-and-reel format with a base quantity of 3200 units per reel (ordering code suffix "I"). It uses matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards, and passes JESD 201 Class 2 whisker testing. The SMB10J24AHE3_A/I reel configuration supports high-speed pick-and-place assembly and meets IPC-A-610 Class 3 process requirements.
