Product details
Overview
SMBG9.0CHE3/52 from Vishay General Semiconductor is a bi-directional transient voltage suppressor (TVS) diode in DO-215AA (SMBG) package, designed for clamping voltage transients on signal or power lines. It features 9.0 V stand-off voltage (VWM), 15.4 V maximum clamping voltage (VC) at 39.0 A peak pulse current (IPPM), and 600 W peak pulse power (PPPM) with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor signal lines in automotive and industrial electronics.
For engineers reviewing the SMBG9.0CHE3/52 datasheet, SMBG9.0CHE3/52 pinout, SMBG9.0CHE3/52 application, or SMBG9.0CHE3/52 equivalent, key selection criteria include bi-directional clamping capability, AEC-Q101 qualification, RoHS-compliant HE3 suffix, 150 °C max junction temperature, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This device operates as a bi-directional avalanche diode, triggering symmetrically in both polarities above its breakdown voltage range of 10.0–11.1 V (VBR at 1 mA). Its low incremental surge resistance and fast response time enable effective suppression of ESD and inductive switching transients without latch-up or degradation under repetitive 0.01% duty cycle conditions.
Thermally, it exhibits RθJA = 100 °C/W and RθJL = 20 °C/W, supporting reliable operation up to TJ = 150 °C. The DO-215AA package meets UL 94 V-0 flammability rating and J-STD-020 MSL Level 1 (260 °C peak reflow), with matte tin-plated leads compliant to JESD 22-B102 solderability and JESD 201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 9.0 V - maximum continuous reverse operating voltage before clamping begins |
| VBR (min/max) | 10.0 V / 11.1 V at 1 mA - ensures predictable bi-directional avalanche turn-on threshold |
| VC @ IPPM | 15.4 V at 39.0 A - limits transient voltage seen by protected circuitry during 10/1000 μs surge |

| TJ max | +150 °C - enables use in under-hood automotive and high-temperature industrial environments |
| Qualification | AEC-Q101 qualified - validated for automotive-grade reliability and stress testing |
| RoHS | HE3 suffix - RoHS-compliant and JESD 201 Class 2 whisker resistant |
Pinout & Package
DO-215AA (SMBG) surface-mount package: low-profile, gull-wing leads, no polarity marking for bi-directional configuration. Dimensions: 6.48 mm × 3.94 mm × 2.10 mm (L × W × H); mounting pad layout requires 5.0 mm × 5.0 mm copper area per terminal per Vishay recommendation.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ9.0CA | Same VWM (9.0 V), higher VC (16.0 V), lower IPPM (37.0 A), same DO-214AA package | Lower peak pulse power (600 W → 600 W same, but lower IPPM reduces margin for high-current transients) | Select SMBJ9.0CA only if board space allows larger DO-214AA footprint and thermal design accommodates higher RθJA (110 °C/W) |
| SMCJ9.0A | Uni-directional variant, same VWM/VBR/VC, but rated for 100 A IFSM and packaged in DO-214AB (SMC) | Requires polarity-aware layout; unsuitable for AC-coupled or floating signal lines where bi-directionality is mandatory | Choose SMCJ9.0A only when protecting DC rails with defined polarity and higher surge current tolerance is required |
Compared with SMBJ9.0CA and SMCJ9.0A, the SMBG9.0CHE3/52 offers AEC-Q101 qualification and JESD 201 Class 2 whisker resistance in the smaller DO-215AA package - making it preferred for space-constrained automotive modules where bi-directional clamping and production reliability are jointly critical.
