Product details
Overview
SMB10J24-E3/52 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-214AA (SMB) package, designed for high-energy surge protection on power rails and signal lines. It features 24 V stand-off voltage (VWM), 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 to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial power supplies.
For engineers reviewing the SMB10J24-E3/52 datasheet, SMB10J24-E3/52 pinout, SMB10J24-E3/52 application, or SMB10J24-E3/52 equivalent, key selection criteria include clamping performance under 25.7 A surge, unidirectional polarity with cathode band marking, AEC-Q101 qualification for automotive use, 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, triggering when reverse voltage exceeds its 26.7–29.5 V breakdown range (VBR at 1 mA). Its glass-passivated junction ensures stable avalanche behavior and low incremental surge resistance, enabling sub-nanosecond response to transients induced by inductive switching or ESD events.
Thermal design relies on RθJA = 72 °C/W and RθJL = 20 °C/W, requiring minimum 0.2" × 0.2" copper pads per terminal for rated 1000 W pulse handling. The E3 suffix confirms RoHS compliance and JESD 201 Class 1A whisker resistance, while the -52 tape-and-reel packaging supports 7" diameter reels with 750 units per reel.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 24 V - Maximum continuous reverse operating voltage before conduction begins; defines safe working margin for 24 V nominal systems. |
| VBR min/max | 26.7 V / 29.5 V - Breakdown occurs within this range at 1 mA test current; ensures reliable turn-on without premature leakage. |
| VC @ IPPM | 38.9 V - Clamped voltage seen by protected circuit during 25.7 A 10/1000 µs surge; limits stress on downstream 36 V-rated components. |
| PPPM | 1000 W - Peak pulse power dissipation capability with standard 10/1000 µs waveform; enables robust protection against IEC 61000-4-5 Level 4 surges. |
| ID @ VWM | 1.0 µA - Reverse leakage at 24 V; negligible power loss and no thermal runaway risk in standby operation. |
| TJ max | 150 °C - Maximum junction temperature; supports operation in under-hood automotive environments and sealed industrial enclosures. |
| Package | DO-214AA (SMB) - Surface-mount outline with 0.220" × 0.155" footprint and cathode band marking; compatible with IPC-7351B SMBJ land patterns. |
Pinout & Package
DO-214AA (SMB) package: two-terminal surface-mount device with molded plastic body, matte tin-plated leads, and cathode band indicating terminal 1 (cathode). Mounting requires 0.2" × 0.2" copper pads per lead for full power rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 (banded end) | Cathode | Connected to system ground or lower-potential rail; reverse-biased during normal operation; conducts surge current to ground when VREV > VBR. |
| Terminal 2 (non-banded end) | Anode | Connected to protected line (e.g., 24 V supply or sensor output); carries surge current into cathode during clamping event. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control units and body electronics, ensuring reliability across temperature cycling and mechanical shock. |
| Low incremental surge resistance | Enables tighter clamping (38.9 V at 25.7 A) versus higher-resistance TVS devices, reducing voltage overshoot on sensitive 24 V logic interfaces. |
| Glass passivated junction | Provides stable, repeatable avalanche characteristics over lifetime and prevents degradation from humidity or contamination in harsh industrial environments. |
| MSL Level 1 (260 °C peak) | Compatible with standard lead-free reflow profiles without preconditioning; eliminates moisture-related popcorning during assembly. |
| RoHS-compliant E3 suffix | Meets JEDEC JESD201 Class 1A whisker resistance and EU Directive 2011/65/EU; suitable for consumer, medical, and industrial BOMs with strict material compliance. |

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 DO-214AA package, identical VWM (24 V), VBR (26.7–29.5 V), and VC (38.9 V); differs only in part numbering convention (SMBJ vs SMB10J series). | No functional difference; both rated for 1000 W PPPM and AEC-Q101; interchangeable in layout and schematic. | Select SMBJ24A-E3/52 if sourcing from distributors listing SMBJ-series stock; electrically and mechanically identical to SMB10J24-E3/52. |
| 1.5SMC24A | Higher-power 1500 W device in larger DO-214AB (SMC) package; same VWM/VBR/VC specs but requires larger PCB footprint and different pad layout. | Suitable where higher single-pulse energy margin is needed (e.g., heavy-duty industrial drives), but not drop-in due to package size mismatch. | Choose 1.5SMC24A only when 1000 W is insufficient and board space allows SMC footprint; otherwise SMB10J24-E3/52 offers optimal power density. |
Compared with SMBJ24A-E3/52, SMB10J24-E3/52 offers identical protection performance in the same compact SMB package, while 1.5SMC24A delivers +50% pulse power at the cost of 40% larger board area and non-interchangeable mounting.

FAQ
What is the clamping voltage of SMB10J24-E3/52 at its rated peak pulse current?
The SMB10J24-E3/52 has a maximum clamping voltage (VC) of 38.9 V when subjected to its rated peak pulse current (IPPM) of 25.7 A with a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 standards and ensures protected circuits experience no more than 38.9 V during worst-case surge events. The SMB10J24-E3/52 maintains this clamping performance across its full operating temperature range of –55 °C to 150 °C.
Is SMB10J24-E3/52 suitable for automotive applications?
Yes, SMB10J24-E3/52 is AEC-Q101 qualified and explicitly rated for automotive use, including engine control units, body electronics, and ADAS camera modules. Its construction includes glass-passivated junctions, MSL Level 1 reflow compatibility, and validated performance across –55 °C to 150 °C junction temperature. The SMB10J24-E3/52 meets requirements for ISO 7637-2 pulse testing and load-dump immunity in 24 V vehicle systems.
What does the "E3/52" suffix mean in SMB10J24-E3/52?
The "E3" suffix indicates RoHS-compliant, commercial-grade construction meeting JEDEC JESD201 Class 1A whisker resistance, while "/52" specifies packaging in 7" diameter plastic tape-and-reel format containing 750 units. This configuration supports automated SMT placement and is documented in Vishay's ordering information table for SMB10J24-E3/52. The SMB10J24-E3/52 is not AEC-Q101 qualified in E3 form-only HE3 variants carry that qualification.
How does SMB10J24-E3/52 differ from bi-directional TVS diodes like SMB8J24CA?
The SMB10J24-E3/52 is unidirectional and features a cathode band for polarity identification, whereas SMB8J24CA is bi-directional with no marking and symmetrical clamping in both directions. SMB10J24-E3/52 offers 1000 W peak pulse power, while SMB8J24CA is rated for 800 W. The SMB10J24-E3/52 is optimized for DC rail protection where polarity is fixed, unlike SMB8J24CA used in AC-coupled or bidirectional signal lines.
What PCB layout guidance applies to SMB10J24-E3/52 for full 1000 W rating?
To achieve the full 1000 W peak pulse power rating, SMB10J24-E3/52 must be mounted on minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, as specified in Vishay's thermal derating curves. Smaller pads increase thermal resistance and reduce surge capability. The SMB10J24-E3/52 also requires short, low-inductance traces to ground and avoidance of vias in the current path to maintain sub-nanosecond response time during transient events.
