Product details
Overview
SMB10J15AHE3/52 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 15 V stand-off voltage (VWM), 16.7–18.5 V breakdown voltage (VBR at 1 mA), 24.4 V clamping voltage (VC) at 41 A peak pulse current, and 1000 W peak pulse power rating with 10/1000 µs waveform.
For engineers reviewing the SMB10J15AHE3/52 datasheet, SMB10J15AHE3/52 pinout, SMB10J15AHE3/52 application, or SMB10J15AHE3/52 equivalent, key selection criteria include AEC-Q101 qualification for automotive use, low incremental surge resistance, glass-passivated junction for reliability, and compatibility with automated SMT placement on standard PCB pad layouts.
Technical Context
This TVS diode operates as a clamping device in parallel with protected circuitry, activating when transient voltage exceeds VWM (15 V) to divert surge current away from sensitive components. Its unidirectional polarity enables DC rail protection without reverse conduction during normal operation.
The device delivers 1000 W peak pulse power handling per 10/1000 µs waveform, with thermal resistance of 72 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead), enabling robust thermal performance under repeated surge events in compact SMB footprint.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 15 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC working range. |
| VBR (min/max) | 16.7 V / 18.5 V - Breakdown voltage range at 1 mA test current; ensures consistent turn-on threshold across production lot. |
| VC @ IPPM | 24.4 V at 41 A - Clamping voltage under full-rated 1000 W surge; limits downstream voltage stress during transients. |
| IPPM | 41 A - Peak pulse current capability with 10/1000 µs waveform; determines maximum energy absorption per event. |
| PPPM | 1000 W - Peak pulse power rating; defines surge energy capacity (1000 W × 1 ms = 1 J) for inductive switching or ESD-like events. |
| TJ max | 150 °C - Maximum junction temperature; supports operation in under-hood automotive environments and industrial enclosures. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock testing. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile plastic case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. Cathode indicated by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry (during clamping) | Connected to lower-potential side of protected line (e.g., GND or return path); conducts surge current to ground. |
| Cathode | Reverse-biased terminal (marked with band) | Connected to higher-potential side (e.g., +12 V rail); blocks normal DC but avalanches during overvoltage. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enhances long-term stability and moisture resistance versus epoxy-passivated alternatives; critical for automotive under-hood life. |
| MSL Level 1 (260 °C peak) | Enables single-reflow assembly without moisture sensitivity concerns; eliminates baking requirement in production. |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (e.g., ISO 7637-2 pulse 1/2a), improving protection margin for downstream ICs. |
| AEC-Q101 qualification (HE3 suffix) | Confirms compliance with automotive stress tests including HTOL, TC, UHAST, and mechanical shock-no additional qualification needed. |
| RoHS-compliant & halogen-free option available | HM3 variant meets strict environmental requirements for Tier 1 automotive suppliers and EU-based industrial OEMs. |

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/VC, but rated for 600 W PPPM; no AEC-Q101 qualification. | Commercial-grade only; unsuitable for automotive or mission-critical industrial deployments. | Select when cost sensitivity outweighs automotive qualification and 1000 W surge headroom is unnecessary. |
| 1.5SMC15A | Same electrical specs, but in larger SMC (DO-214AB) package; 1.5× footprint area; RθJA = 40 °C/W. | Higher thermal mass allows longer surge duration tolerance but requires more PCB area. | Choose when board space permits and improved thermal dissipation justifies larger package. |

FAQ
What is the clamping voltage of SMB10J15AHE3/52 at its rated peak pulse current?
The SMB10J15AHE3/52 has a maximum clamping voltage (VC) of 24.4 V at its rated peak pulse current (IPPM) of 41 A, measured using the standardized 10/1000 µs double-exponential surge waveform. This value ensures downstream components see no more than 24.4 V during full-rated transient events, making SMB10J15AHE3/52 suitable for protecting 24 V nominal systems with adequate safety margin.
Is SMB10J15AHE3/52 qualified for automotive applications?
Yes, SMB10J15AHE3/52 carries the HE3 suffix, confirming it is RoHS-compliant and AEC-Q101 qualified. This certification covers stress tests including high-temperature operating life (HTOL), temperature cycling (TC), unbiased highly accelerated stress test (UHAST), and mechanical shock-validating SMB10J15AHE3/52 for under-hood and chassis-mounted automotive electronics without additional qualification effort.
What is the standoff voltage and breakdown voltage range for SMB10J15AHE3/52?
The SMB10J15AHE3/52 has a standoff voltage (VWM) of 15 V and a breakdown voltage (VBR) range of 16.7 V to 18.5 V at 1 mA test current. This 1.7 V margin between VWM and minimum VBR prevents false triggering during normal operation while ensuring rapid avalanche onset during overvoltage events-critical for reliable protection in noisy 12 V automotive systems.
Does SMB10J15AHE3/52 have a bidirectional version?
No, SMB10J15AHE3/52 is unidirectional only. The bidirectional counterpart in the same family is SMB8J15CAHE3/52, which provides symmetrical clamping for AC-coupled or floating signal lines. SMB10J15AHE3/52's unidirectional configuration makes it ideal for DC power rail protection where polarity is fixed and reverse conduction must be blocked during normal operation.
What package type and mounting specifications apply to SMB10J15AHE3/52?
SMB10J15AHE3/52 uses the SMB (DO-214AA) surface-mount package with cathode indicated by a color band. It is designed for reflow soldering on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, complies with MSL Level 1 (peak reflow temperature 260 °C), and features matte tin-plated leads meeting J-STD-002 and JESD 22-B102 solderability standards-ensuring robust manufacturability in high-volume SMT lines.
