Product details
Overview
SMB10J15AHE3/5B 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 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 (IPPM), and 1000 W peak pulse power (PPPM) with 10/1000 µs waveform - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the SMB10J15AHE3/5B datasheet, SMB10J15AHE3/5B pinout, SMB10J15AHE3/5B application, or SMB10J15AHE3/5B equivalent, key selection criteria include AEC-Q101 qualification, unidirectional polarity, low clamping ratio (VC/VWM = 1.63), and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal conditions it presents <1 µA leakage at 15 V (VWM), then rapidly avalanches when transients exceed VBR (16.7–18.5 V), limiting downstream voltage to ≤24.4 V at 41 A surge. Its glass-passivated junction ensures stable breakdown and low incremental surge resistance.
Thermally, it sustains operation from −55 °C to +150 °C junction temperature, with RθJA = 72 °C/W and RθJL = 20 °C/W. The device meets MSL Level 1 per J-STD-020 and is qualified to AEC-Q101 for automotive use - confirmed by HE3 suffix and Vishay's revision-validated compliance documentation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 15 V - maximum continuous reverse operating voltage before conduction begins; defines safe DC rail margin. |
| VBR min/max | 16.7 V / 18.5 V at 1 mA - precise avalanche onset range ensuring consistent turn-on across production lots. |
| VC @ IPPM | 24.4 V at 41 A - clamped voltage during 10/1000 µs surge; limits stress on protected ICs like microcontrollers or CAN transceivers. |
| PPPM | 1000 W - peak pulse power handling capability; supports robust protection against ISO 7637-2 Pulse 1/2/5a surges. |
| ID @ VWM | ≤1.0 µA - ultra-low leakage preserves battery life and avoids false triggering in low-power sensor nodes. |
| TJ max | +150 °C - enables deployment in under-hood automotive environments and industrial enclosures without derating. |
| AEC-Q101 | Qualified - validated 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 matte tin-plated leads solderable per J-STD-002. Cathode indicated by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / surge return path | Connected to protected line (e.g., 12 V rail); conducts during positive transients when cathode is biased higher. |
| Cathode | Clamping reference / surge sink | Connected to ground or lower-potential rail; establishes clamping threshold relative to anode via VBR and VC. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive electronics including engine control units and ADAS sensor modules - no requalification needed for Tier 1 designs. |
| 1000 W peak pulse power | Withstands ≥41 A 10/1000 µs surges on 12 V systems - exceeds ISO 7637-2 Pulse 5a requirements for 24 V commercial vehicles. |
| Low clamping ratio (VC/VWM = 1.63) | Minimizes overvoltage exposure to downstream logic; critical for protecting 3.3 V or 5 V interface ICs sharing same rail. |
| MSL Level 1 moisture sensitivity | Enables direct placement without baking; compatible with standard reflow profiles up to 260 °C peak. |
| Glass passivated junction | Ensures stable VBR over lifetime and temperature; eliminates parameter drift seen in epoxy-passivated alternatives. |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |

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-E3/5B | Same VWM (15 V), VBR (16.7–18.5 V), and VC (24.4 V), but rated for 600 W PPPM (vs. 1000 W). | Limited to lower-energy transients (e.g., IEC 61000-4-4 Level 3); insufficient for ISO 7637-2 Pulse 5a. | Select SMB10J15AHE3/5B where full 1000 W surge immunity is required; SMBJ15A-E3/5B suits cost-sensitive consumer designs with lower threat profiles. |
| 1.5SMC15AHE3/A | Same electrical specs but in larger SMC (DO-214AB) package; RθJA = 30 °C/W (vs. 72 °C/W for SMB). | Better thermal performance allows higher duty-cycle surge handling; requires larger PCB footprint (7.11 mm × 6.22 mm vs. 4.57 mm × 3.94 mm). | Choose SMB10J15AHE3/5B for space-constrained automotive modules; select 1.5SMC15AHE3/A for industrial power supplies needing extended thermal margin. |

FAQ
What is the clamping voltage of SMB10J15AHE3/5B at its rated peak pulse current?
The SMB10J15AHE3/5B has a maximum clamping voltage (VC) of 24.4 V when subjected to its rated peak pulse current (IPPM) of 41 A using the 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and confirmed in Vishay's Document Number 88422, ensuring predictable overvoltage limiting for protected circuitry downstream of SMB10J15AHE3/5B.
Is SMB10J15AHE3/5B suitable for automotive applications?
Yes, SMB10J15AHE3/5B is AEC-Q101 qualified and carries the HE3 suffix denoting RoHS-compliant and automotive-grade qualification. It is explicitly validated for under-hood and chassis-mounted applications, including engine control sensors and ADAS camera power inputs, with full test reports covering temperature cycling, HTRB, and surge endurance per AEC-Q101 Rev D.
What is the standoff voltage rating for SMB10J15AHE3/5B?
The standoff voltage (VWM) for SMB10J15AHE3/5B is 15 V - the maximum DC or continuous reverse voltage the device can withstand without entering avalanche conduction. This rating ensures reliable operation on nominal 12 V automotive systems and 15 V industrial rails, with ≤1.0 µA leakage current at this voltage per Vishay's datasheet specifications.
Does SMB10J15AHE3/5B have polarity markings, and how is it oriented on PCB?
Yes, SMB10J15AHE3/5B is unidirectional and marked with a cathode band on the SMB (DO-214AA) package body. During PCB layout, the banded end must connect to ground or the lower-potential reference node, while the unmarked end connects to the line being protected - correct orientation ensures proper clamping action during positive transients.
What is the thermal resistance from junction to ambient for SMB10J15AHE3/5B?
The typical thermal resistance from junction to ambient (RθJA) for SMB10J15AHE3/5B is 72 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, as specified in Vishay's Document Number 88422. This value assumes standard JEDEC test conditions and guides thermal design for sustained surge duty cycles involving SMB10J15AHE3/5B.
