Product details
Overview
SMBG6.5CHE3/52 from Vishay General Semiconductor is a bi-directional transient voltage suppressor (TVS) diode in DO-215AA (SMBG) package, designed for clamping inductive switching transients and ESD events on signal/power lines. It features 6.5 V stand-off voltage (VWM), 7.22–7.98 V breakdown voltage (VBR) at 10 mA, 11.2 V maximum clamping voltage (VC) at 53.6 A peak pulse current (IPPM), and 600 W peak pulse power rating with 10/1000 μs waveform - used in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the SMBG6.5CHE3/52 datasheet, SMBG6.5CHE3/52 pinout, SMBG6.5CHE3/52 application, or SMBG6.5CHE3/52 equivalent, key selection considerations include bi-directional clamping capability, AEC-Q101 qualification, RoHS-compliant HE3 termination, 150 °C junction temperature rating, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This bi-directional TVS operates symmetrically in both polarities, with identical VBR min/max (7.22 V / 7.98 V), VC = 11.2 V at IPPM = 53.6 A, and ID ≤ 500 μA at VWM = 6.5 V. Its glass-passivated junction ensures stable leakage and fast response (<1 ns), while low incremental surge resistance enables effective energy diversion during transients.
The device meets MSL Level 1 per J-STD-020 (peak reflow 260 °C), supports 0.01% duty cycle repetitive surges, and is qualified to AEC-Q101 for automotive under-hood applications. Thermal resistance is RθJA = 100 °C/W (on 5.0 mm × 5.0 mm pads) and RθJL = 20 °C/W.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.5CA | Same VWM (6.5 V), higher PPPM (600 W), but lower IPPM (53.6 A vs. SMBJ6.5CA's 54.5 A); identical DO-214AA package | Not AEC-Q101 qualified; intended for commercial/industrial use only | Select SMBG6.5CHE3/52 when automotive qualification and HE3 whisker resistance are required |
| SMAJ6.5CA | Lower PPPM (400 W), smaller DO-214AC (SMA) package, higher thermal resistance (RθJA = 150 °C/W) | Limited to lower-energy transients; unsuitable for ISO 7637-2 Pulse 1 compliance | Choose SMBG6.5CHE3/52 where 600 W surge margin and automotive-grade reliability are mandatory |
Compared with SMBJ6.5CA and SMAJ6.5CA, SMBG6.5CHE3/52 delivers AEC-Q101 assurance and superior thermal performance in DO-215AA, making it the preferred choice for automotive and high-reliability industrial designs requiring validated surge immunity.

FAQ
What is the clamping voltage of SMBG6.5CHE3/52 under a 10/1000 μs surge?
The SMBG6.5CHE3/52 has a maximum clamping voltage (VC) of 11.2 V at its rated peak pulse current (IPPM) of 53.6 A with a 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during standardized surge events. The SMBG6.5CHE3/52 maintains this clamping performance across its qualified operating temperature range.
Is SMBG6.5CHE3/52 suitable for automotive applications?
Yes, SMBG6.5CHE3/52 is AEC-Q101 qualified and carries the HE3 suffix indicating RoHS compliance and JESD 201 Class 2 whisker resistance - both essential for automotive under-hood and chassis-mounted systems. Its 150 °C maximum junction temperature and robust 600 W surge rating align with ISO 7637-2 requirements. The SMBG6.5CHE3/52 is explicitly listed in Vishay's AEC-Q101 qualified product documentation.
What does the "HE3" suffix mean in SMBG6.5CHE3/52?
The "HE3" suffix in SMBG6.5CHE3/52 indicates RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. Unlike the commercial "E3" variant, HE3 ensures enhanced metallurgical reliability for automotive and high-reliability industrial use. The SMBG6.5CHE3/52 also features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards.
How does SMBG6.5CHE3/52 differ from uni-directional SMBG6.5A?
SMBG6.5CHE3/52 is bi-directional with symmetrical clamping in both polarities and no cathode band marking, whereas SMBG6.5A is uni-directional with a visible cathode band and forward voltage drop (~3.5 V at 50 A). The SMBG6.5CHE3/52 supports AC-coupled or differential signal protection, while SMBG6.5A is limited to DC-biased lines. Their VWM, VBR, and VC values are otherwise closely matched.
What PCB pad layout is recommended for SMBG6.5CHE3/52?
Vishay specifies a minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pad area per terminal for SMBG6.5CHE3/52 to achieve rated thermal performance (RθJA = 100 °C/W) and 600 W pulse power dissipation. The DO-215AA outline drawing confirms 0.077–0.083" lead width and 0.130–0.155" body length. Proper pad sizing ensures reliable solder joints and prevents thermal derating in high-surge applications using SMBG6.5CHE3/52.
