Product details
Overview
SMBG64AHE3/52 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMBG (DO-215AA) package, designed for robust overvoltage protection of sensitive electronics. It features a 64 V stand-off voltage (VWM), 71.1–78.6 V breakdown voltage (VBR) at 1 mA, 103 V maximum clamping voltage (VC) at 5.8 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive sensor signal lines, industrial I/O interfaces, and DC power rail protection.
For engineers reviewing the SMBG64AHE3/52 datasheet, SMBG64AHE3/52 pinout, SMBG64AHE3/52 application, or SMBG64AHE3/52 equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), junction temperature range (−55 to +150 °C), and packaging details for rapid design-in and reliability validation.
Technical Context
This unidirectional TVS diode operates as a clamping device that remains high-impedance below 64 V and rapidly transitions to low-impedance conduction above its 71.1–78.6 V breakdown threshold. Its glass-passivated junction ensures stable leakage performance (<1.0 μA at VWM) and fast response time (<1 ns), enabling effective suppression of ESD, lightning-induced surges, and inductive switching transients.
Rated for 600 W peak pulse power (10/1000 μs), it sustains repetitive surges at 0.01% duty cycle and handles up to 100 A non-repetitive forward surge current (8.3 ms half-sine). The SMBG (DO-215AA) package supports automated placement and meets MSL level 1 (260 °C reflow peak) and AEC-Q101 qualification for automotive-grade reliability.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64A-E3/52 | Same VWM (64 V), but lower PPPM (600 W vs. SMBJ's 600 W), identical SMB (DO-214AA) package footprint - slightly larger body height and higher RθJA (110 °C/W) | Compatible in board space-constrained designs where DO-214AA layout exists; less optimal thermal performance on same pad size | Select when legacy SMB layout is fixed and AEC-Q101 not required - SMBJ64A lacks automotive qualification |
| SMCJ64AHE3/52 | Same VWM and AEC-Q101 rating, but SMC (DO-214AB) package - 1500 W PPPM, higher IPPM (12.3 A), larger footprint and thermal mass | Used where higher surge immunity is mandated (e.g., 10/1000 μs 2× energy), but requires PCB redesign due to larger pad layout | Choose for mission-critical 48 V systems needing >1 kW surge headroom; not drop-in compatible with SMBG layout |
Compared with SMBJ64A-E3/52 and SMCJ64AHE3/52, SMBG64AHE3/52 uniquely balances AEC-Q101 compliance, compact SMBG footprint, and 600 W capability - making it optimal for space-limited automotive sensors and industrial edge nodes where thermal management and qualification are jointly critical.

FAQ
What is the clamping voltage of SMBG64AHE3/52 and how is it measured?
The SMBG64AHE3/52 has a maximum clamping voltage (VC) of 103 V, measured at 5.8 A peak pulse current (IPPM) using a 10/1000 μs double-exponential waveform. This value reflects the actual voltage seen by downstream circuitry during a standardized surge event and is guaranteed per the Vishay datasheet revision 09-Jan-2024. The SMBG64AHE3/52 maintains this clamping performance across its full operating temperature range.
Is SMBG64AHE3/52 suitable for automotive applications?
Yes, SMBG64AHE3/52 is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood and ADAS sensor modules. Its construction includes glass-passivated junction, matte tin-plated leads compliant with J-STD-002, and MSL Level 1 moisture sensitivity - all validated per automotive stress test requirements. The SMBG64AHE3/52 datasheet confirms qualification status in the Mechanical Data section.
What does the "HE3" suffix mean in SMBG64AHE3/52?
The "HE3" suffix in SMBG64AHE3/52 indicates RoHS-compliant, AEC-Q101 qualified construction with matte tin plating and JESD201 Class 2 whisker resistance. It distinguishes this variant from industrial-grade "E3" (RoHS, no AEC-Q101) and halogen-free "HM3" versions. The "52" denotes 7″ tape-and-reel packaging with 750 units per reel - confirmed in the Ordering Information table.
How does SMBG64AHE3/52 compare to bidirectional TVS diodes like SMBG64CA?
SMBG64AHE3/52 is unidirectional and intended for DC-biased lines where polarity is fixed (e.g., power rails, single-ended signals); SMBG64CA is bidirectional and used for AC or floating lines (e.g., data buses). They share identical VWM, VBR, and PPPM ratings, but SMBG64AHE3/52 exhibits forward conduction behavior and requires correct anode/cathode orientation. The SMBG64AHE3/52 datasheet specifies polarity via cathode band marking.
What is the thermal resistance of SMBG64AHE3/52 and how does it affect layout?
The SMBG64AHE3/52 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 assumes standard FR-4 PCB with no internal planes; adding thermal vias or increasing copper area reduces RθJA. Layout must follow the recommended mounting pad dimensions in the Vishay SMBG outline drawing to ensure rated surge performance and avoid thermal runaway during repetitive events.
