Product details
Overview
SMBG10CAHE3/5B from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMBG (DO-215AA) package, designed for robust overvoltage protection on signal and power lines. It features 10 V stand-off voltage (VWM), 11.1–12.3 V breakdown voltage (VBR) at 1 mA, 17.0 V maximum clamping voltage (VC) at 35.3 A peak pulse current (IPPM), and 600 W peak pulse power (PPPM) with 10/1000 μs waveform - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the SMBG10CAHE3/5B datasheet, SMBG10CAHE3/5B pinout, SMBG10CAHE3/5B application, or SMBG10CAHE3/5B equivalent, key selection criteria include bidirectional clamping symmetry, AEC-Q101 qualification, low clamping ratio (VC/VBR ≈ 1.53), MSL Level 1 moisture sensitivity, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This device operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 MΩ at 10 V), but triggers into low-impedance conduction when transient voltage exceeds VBR in either polarity. Its glass-passivated junction ensures stable leakage and fast response (<1 ns), while the DO-215AA package enables thermal dissipation up to 100 °C/W junction-to-ambient.
The SMBG10CAHE3/5B is rated for -55 °C to +150 °C operating junction temperature, supports repetitive 0.01% duty cycle surges, and meets UL 497B recognition (QVGQ2) for telecom and industrial protectors - with no polarity marking required due to symmetrical bidirectional construction.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - maximum continuous reverse working voltage before clamping begins |
| VBR min/max | 11.1 V / 12.3 V at 1 mA - guaranteed breakdown threshold in both directions |
| VC @ IPPM | 17.0 V at 35.3 A - clamping voltage limits downstream IC stress during 10/1000 μs transients |
| PPPM | 600 W - peak surge power handling per single 10/1000 μs pulse |
| TJ max | +150 °C - maximum junction temperature enabling operation in under-hood automotive environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10CA-E3/5B | Same VWM/VBR/VC specs, but SMBJ (DO-214AB) package - 1.58 mm taller, 0.2 mm wider body | Less board space efficiency; higher RθJA (120 °C/W vs. 100 °C/W) reduces surge margin at elevated ambient | Select when legacy SMBJ footprint exists or higher IFSM (100 A) is needed for unidirectional variants |
| 1.5KE10CA | Through-hole TO-218 package; same electrical specs but 1500 W PPPM rating and 100 A IFSM | Not suitable for high-density SMT designs; requires wave solder or hand assembly | Choose only for prototyping, low-volume repair, or where thermal mass from lead-frame improves long-duration surge survival |
Compared with SMBJ10CA-E3/5B and 1.5KE10CA, the SMBG10CAHE3/5B delivers optimal SMT manufacturability, AEC-Q101 compliance, and thermal performance in space-constrained automotive and industrial modules - without requiring PCB redesign or sacrificing surge robustness.

FAQ
What is the clamping voltage of SMBG10CAHE3/5B at its rated peak pulse current?
The SMBG10CAHE3/5B has a maximum clamping voltage (VC) of 17.0 V when subjected to its peak pulse current (IPPM) of 35.3 A under the standard 10/1000 μs waveform. This value is measured per Figure 1 in Vishay document 88456 and defines the upper voltage limit imposed on protected circuitry during surge events - critical for ensuring downstream ICs remain within their absolute maximum ratings.
Is SMBG10CAHE3/5B suitable for automotive applications?
Yes, SMBG10CAHE3/5B is AEC-Q101 qualified and explicitly rated for automotive use. Its construction includes glass-passivated junctions, MSL Level 1 handling, and operation from -55 °C to +150 °C junction temperature - meeting requirements for engine control units, body electronics, and ADAS sensor interfaces. The HE3 suffix confirms AEC-Q101 qualification per Vishay's ordering nomenclature.
Does SMBG10CAHE3/5B have polarity markings on the package?
No, SMBG10CAHE3/5B does not feature polarity markings because it is a bidirectional TVS diode. The device exhibits identical electrical characteristics in both directions - VBR, VC, and leakage are symmetric - so orientation during placement has no functional impact. This simplifies PCB layout and eliminates risk of incorrect installation.
What is the thermal resistance of SMBG10CAHE3/5B, and how does it affect surge capability?
SMBG10CAHE3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value directly impacts sustained surge handling: lower RθJA allows faster heat dissipation, preserving clamping performance during repetitive transients and extending device lifetime in high-temperature environments.
How does the 600 W peak pulse power rating of SMBG10CAHE3/5B compare to industry standards?
The 600 W PPPM rating of SMBG10CAHE3/5B aligns with IEC 61000-4-5 Level 4 (4 kV line-to-earth, 2 kV line-to-line) and ISO 7637-2 Pulse 1/2a/3a test profiles. It exceeds minimum requirements for most industrial and automotive applications - delivering 2× the energy absorption of 300 W-rated SMB-type TVS devices - while maintaining compact SMBG footprint and AEC-Q101 compliance.
