Product details
Overview
SMBJ6.5CHE3/52 from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed to protect sensitive electronics against ESD, lightning-induced surges, and inductive switching transients. It features a 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, and 600 W peak pulse power rating with 10/1000 µs waveform.
For engineers reviewing the SMBJ6.5CHE3/52 datasheet, SMBJ6.5CHE3/52 pinout, SMBJ6.5CHE3/52 application, or SMBJ6.5CHE3/52 equivalent, key selection criteria include clamping performance under 53.6 A surge, AEC-Q101 qualification for automotive use, RoHS-compliant matte tin terminals, and compatibility with automated SMT placement on PCBs with 5.0 mm × 5.0 mm copper pads per terminal.
Technical Context
This TVS diode operates as a unidirectional clamping device with cathode-band polarity marking, leveraging a glass-passivated silicon junction for stable avalanche behavior. Its thermal resistance is 100 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead), enabling reliable operation up to 150 °C junction temperature under defined PCB pad conditions.
The SMBJ6.5CHE3/52 delivers fast response time (<1 ps), low incremental surge resistance, and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak. It is rated for 100 A non-repetitive forward surge current (8.3 ms half-sine) and exhibits a VBR temperature coefficient of +0.061 %/°C - critical for stability across automotive temperature ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 6.5 V - maximum continuous reverse voltage before significant leakage; sets operating margin below breakdown |
| VBR (Breakdown Voltage) | 7.22–7.98 V at 10 mA - defines precise avalanche initiation threshold for predictable clamping onset |
| VC (Clamping Voltage) | 11.2 V at 53.6 A (10/1000 µs) - limits transient voltage seen by protected IC/MOSFET during surge events |
| PPPM (Peak Pulse Power) | 600 W - sustains high-energy transients without failure when mounted on 5.0 mm × 5.0 mm copper pads |
| IPPM (Peak Pulse Current) | 53.6 A - maximum surge current handled at rated clamping voltage; determines protection level for IEC 61000-4-5 |
| TJmax | 150 °C - enables use in under-hood automotive environments and industrial enclosures with elevated ambient temps |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC standard |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. Polarity indicated by cathode band on one end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / Surge return path | Connected to ground or low-impedance reference plane; completes clamping loop during transient |
| Cathode | Protected line connection / Surge sink | Connected to signal/power line being protected; avalanche conduction occurs from cathode to anode |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 µs) | Enables robust protection against IEC 61000-4-5 Level 4 surges (4 kV line-to-ground) without derating on standard PCB layouts |
| AEC-Q101 qualified (HE3 suffix) | Validated for automotive applications including engine control units, body electronics, and ADAS sensor interfaces |
| Glass passivated junction | Ensures long-term parameter stability and low leakage drift over temperature and lifetime vs. epoxy-passivated alternatives |
| MSL Level 1 (260 °C peak) | Supports standard lead-free reflow profiles without preconditioning or special handling requirements |
| Low clamping ratio (VC/VBR ≈ 1.45) | Minimizes overvoltage stress on downstream components during clamping - critical for 3.3 V and 5 V logic interfaces |
Applications
| Automotive Body Control Module (BCM) | Industrial PLC Digital Input Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.5AHE3/52 | Same electrical specs and AEC-Q101 qualification; differs only in packaging code (HE3 vs. HE3/52 denotes tape-and-reel quantity) | No functional difference; identical performance and footprint | Select SMBJ6.5CHE3/52 for verified 750-unit 7" reel delivery; SMBJ6.5AHE3/52 may reflect alternate reel size or internal revision tracking |
| SMCJ6.5AHE3/52 | Same VWM, VBR, and VC, but in larger SMC (DO-214AB) package with 1500 W PPPM rating and higher IPPM (111 A) | Better suited for higher-energy surges; requires larger PCB area and different pad layout | Choose SMBJ6.5CHE3/52 when board space is constrained and 600 W protection suffices; upgrade to SMCJ6.5AHE3/52 only if IEC 61000-4-5 Level 5 compliance is required |
Compared with SMBJ6.5AHE3/52, SMBJ6.5CHE3/52 offers identical protection performance in the same AEC-Q101-qualified configuration; versus SMCJ6.5AHE3/52, it trades peak power headroom for compact SMB footprint - making it optimal for space-constrained automotive and industrial PCBs where 600 W clamping is sufficient.

FAQ
What is the clamping voltage of SMBJ6.5CHE3/52 at its rated peak pulse current?
The SMBJ6.5CHE3/52 has a maximum clamping voltage (VC) of 11.2 V at 53.6 A peak pulse current with a 10/1000 µs waveform. This value is measured under standardized test conditions with the device mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, ensuring repeatable surge suppression performance in real-world PCB layouts.
Is SMBJ6.5CHE3/52 qualified for automotive applications?
Yes, SMBJ6.5CHE3/52 is AEC-Q101 qualified, as confirmed by the "HE3" suffix in its part number. This certification covers stress tests including high-temperature reverse bias (HTRB), temperature cycling, and ESD robustness - validating its suitability for under-hood and cabin-mounted automotive electronics such as body control modules and sensor interfaces.
What does the "/52" suffix indicate in SMBJ6.5CHE3/52?
The "/52" suffix in SMBJ6.5CHE3/52 specifies the preferred packaging format: 750 units per 7-inch diameter plastic tape-and-reel. This is a standard delivery option optimized for high-volume SMT assembly lines and ensures consistent feeding performance in pick-and-place equipment calibrated for that reel size and orientation.
How does SMBJ6.5CHE3/52 differ from bidirectional variants like SMBJ6.5CHE3/52CA?
SMBJ6.5CHE3/52 is unidirectional and features a cathode band for polarity identification, while bidirectional versions (e.g., SMBJ6.5CHE3/52CA) have no polarity marking and suppress transients in both directions. The unidirectional SMBJ6.5CHE3/52 provides lower leakage and tighter VBR tolerance for DC-biased lines, whereas bidirectional types suit AC-coupled or floating signal paths.
What is the maximum operating junction temperature for SMBJ6.5CHE3/52?
The SMBJ6.5CHE3/52 has a maximum operating junction temperature (TJmax) of +150 °C, as specified in the Vishay datasheet. This rating supports reliable operation in high-ambient environments such as automotive engine compartments and industrial control cabinets, provided thermal design accounts for its 100 °C/W junction-to-ambient thermal resistance.
