Product details
Overview
SMBG9.0HE3/52 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-215AA (SMBG) package, designed for clamping inductive switching transients and ESD events on power rails and signal lines. It features 9.0 V stand-off voltage, 10.0–11.1 V breakdown voltage at 1 mA, 15.4 V maximum clamping voltage at 39.0 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform.
For engineers reviewing the SMBG9.0HE3/52 datasheet, SMBG9.0HE3/52 pinout, SMBG9.0HE3/52 application, or SMBG9.0HE3/52 equivalent, key selection criteria include unidirectional polarity, 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 TVS diode operates as a voltage-clamping protection device in series with DC power inputs or parallel to sensitive ICs. Its glass-passivated junction enables fast response (<1 ns), low incremental surge resistance, and stable clamping under repetitive 0.01% duty cycle surges.
The SMBG9.0HE3/52 is rated for 100 A non-repetitive forward surge current (8.3 ms half-sine), exhibits 1.0 µA max reverse leakage at 9.0 V, and maintains thermal resistance of 100 °C/W (junction-to-ambient) when mounted per recommended pad layout.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ9.0AHE3/52 | Same VWM (9.0 V), but higher PPPM (600 W vs. SMBJ's 600 W), identical DO-215AA package and AEC-Q101 qualification | No functional difference; SMBJ series uses same die but different branding and minor test condition variations | Select SMBG9.0HE3/52 when referencing Vishay's TRANSZORB®-branded SMBG family documentation or legacy BOMs |
| 1.5SMC9.0A | Same VWM (9.0 V) and clamping (15.4 V), but larger DO-214AB (SMC) package and higher thermal resistance (125 °C/W) | Requires larger PCB footprint and delivers lower surge current derating above 25 °C ambient | Choose SMBG9.0HE3/52 for space-constrained automotive modules where DO-215AA's 100 °C/W RθJA improves thermal margin |
Compared with SMBJ9.0AHE3/52, SMBG9.0HE3/52 offers identical electrical performance in a functionally interchangeable package; versus 1.5SMC9.0A, it provides superior thermal performance and smaller footprint-critical for high-density automotive ECUs and sensor nodes.

FAQ
What is the polarity configuration of SMBG9.0HE3/52?
The SMBG9.0HE3/52 is a unidirectional transient voltage suppressor diode, with cathode identified by a molded band on the DO-215AA package body. It conducts only when the cathode is biased positively relative to the anode, making it suitable for DC rail protection where polarity is fixed. This differs from bi-directional variants (e.g., SMBG9.0CA) that suppress transients in both directions.
Does SMBG9.0HE3/52 meet automotive reliability standards?
Yes, SMBG9.0HE3/52 carries the HE3 suffix, confirming AEC-Q101 qualification per Vishay's documentation. It has undergone stress testing including temperature cycling, highly accelerated life testing (HALT), and surge endurance validation-making it approved for use in engine control units, body electronics, and ADAS subsystems.
What is the maximum clamping voltage of SMBG9.0HE3/52 under surge conditions?
The SMBG9.0HE3/52 has a maximum clamping voltage (VC) of 15.4 V at 39.0 A peak pulse current, measured using the standard 10/1000 µs waveform. This value ensures downstream 16 V-rated ICs remain within safe operating limits during transient events such as load dump or inductive kickback.
How does the HE3 suffix differ from E3 in SMBG9.0HE3/52?
The HE3 suffix in SMBG9.0HE3/52 denotes RoHS-compliance plus AEC-Q101 qualification and JESD201 Class 2 whisker resistance. In contrast, the E3 suffix indicates RoHS compliance only (commercial grade, no automotive qualification). Both share identical electrical specs and DO-215AA packaging, but HE3 is required for automotive designs.
What PCB pad layout is recommended for optimal thermal performance of SMBG9.0HE3/52?
Vishay specifies mounting SMBG9.0HE3/52 on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal to achieve the rated 100 °C/W junction-to-ambient thermal resistance. Reducing pad area increases thermal impedance and reduces surge current derating-especially critical in high-temperature automotive under-hood applications.
