Product details
Overview
SMB10J6.5-E3/52 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-214AA (SMB) package, designed for high-energy surge protection on DC power rails and signal lines. It features 6.5 V stand-off voltage (VWM), 7.22–7.98 V breakdown voltage (VBR) at 10 mA, 11.2 V clamping voltage (VC) at 89.3 A peak pulse current (IPPM), and 1000 W peak pulse power (PPPM) with 10/1000 µs waveform.
For engineers reviewing the SMB10J6.5-E3/52 datasheet, SMB10J6.5-E3/52 pinout, SMB10J6.5-E3/52 application, or SMB10J6.5-E3/52 equivalent, key selection criteria include clamping performance under 100 A surge, unidirectional polarity for DC rail protection, RoHS-compliant commercial-grade packaging (E3 suffix), and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
This TVS diode operates as a voltage-clamped crowbar device during transients, leveraging an avalanche junction to clamp induced surges before downstream ICs or MOSFETs are damaged. Its glass-passivated chip junction ensures stable breakdown behavior and low leakage (<1000 µA at VWM), while MSL Level 1 rating confirms suitability for lead-free reflow up to 260 °C.
The SMB10J6.5-E3/52 delivers 1000 W peak pulse power handling with 11.2 V clamping at 89.3 A, enabling robust protection against ISO 7637-2 Load Dump and IEC 61000-4-5 surge events. Thermal resistance of 72 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead) supports sustained operation up to 150 °C junction temperature in compact PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.5 V - Maximum continuous reverse operating voltage; defines safe DC rail margin before conduction begins. |
| VBR min/max | 7.22 V / 7.98 V at 10 mA - Tight breakdown window ensures predictable turn-on across production lots. |
| VC @ IPPM | 11.2 V at 89.3 A - Clamping voltage during 10/1000 µs surge; limits stress on protected 5–12 V logic or power stages. |
| PPPM | 1000 W - Peak surge energy absorption capability; meets automotive load dump and industrial switching transient requirements. |
| ID @ VWM | ≤1000 µA - Low reverse leakage preserves battery life and avoids false triggering in low-power sensor interfaces. |
| TJ max | 150 °C - Enables use in under-hood automotive modules and industrial controllers without derating at ambient ≤85 °C. |
| Package | DO-214AA (SMB) - Standardized surface-mount outline with cathode band marking; compatible with JEDEC J-STD-020 MSL Level 1. |
Pinout & Package
DO-214AA (SMB) package: molded plastic case with matte tin-plated leads, cathode indicated by color band on one end. Dimensions: 4.57 mm × 3.94 mm × 2.20 mm (L × W × H); recommended pad layout: 5.0 mm × 5.0 mm copper per terminal.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference node | Connected to ground or return path; forms clamping loop with cathode during positive transients. |
| Cathode | Protected line input | Connected to supply rail or signal line; conducts avalanche current to anode when voltage exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| Uni-directional polarity | Enables DC rail protection without forward conduction during normal operation; cathode-band marking simplifies orientation verification. |
| AEC-Q101 qualification (HE3 variant only) | This E3-suffix part is commercial grade; HE3 variant required for automotive under-hood applications per AEC-Q101 stress testing. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., inductive switch-off), improving clamping fidelity vs. higher-Rsurge TVS devices. |
| MSL Level 1 moisture sensitivity | Allows unlimited floor life and standard reflow profile (peak 260 °C), eliminating bake requirements prior to assembly. |
| Glass passivated junction | Ensures long-term stability of VBR and leakage parameters across thermal cycling and humidity exposure. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.5A | Same VWM (6.5 V), identical DO-214AA package, but rated for 600 W PPPM (vs. 1000 W). | Limited to lower-energy transients (e.g., IEC 61000-4-4 EFT), not suitable for automotive load dump. | Select SMBJ6.5A only if system-level surge testing confirms <600 W requirement and cost is prioritized over headroom. |
| SMB10J6.5HE3/52 | Identical electrical specs, but HE3 suffix denotes AEC-Q101 qualification and enhanced whisker resistance (JESD 201 Class 2). | Required for automotive under-hood applications; E3 version lacks qualification documentation for PPAP submission. | Choose SMB10J6.5HE3/52 when automotive OEM compliance is mandatory; E3 suffices for industrial/commercial designs. |
Compared with SMBJ6.5A, SMB10J6.5-E3/52 provides 67% higher surge power margin critical for automotive and industrial environments; versus SMB10J6.5HE3/52, it offers identical clamping and thermal performance at lower qualification cost for non-automotive use cases.

FAQ
What is the maximum clamping voltage of SMB10J6.5-E3/52 under surge conditions?
The SMB10J6.5-E3/52 has a maximum clamping voltage (VC) of 11.2 V at 89.3 A peak pulse current with a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 standards and ensures downstream 12 V logic or power stages remain within safe operating limits during transient events. The SMB10J6.5-E3/52 maintains this clamping performance across its full operating temperature range.
Is SMB10J6.5-E3/52 suitable for automotive applications?
SMB10J6.5-E3/52 is RoHS-compliant and rated for 150 °C junction temperature, but it carries the E3 suffix indicating commercial-grade qualification-not AEC-Q101. For automotive under-hood use, the HE3-suffix variant (SMB10J6.5HE3/52) is required. The SMB10J6.5-E3/52 remains appropriate for non-safety-critical automotive interior modules where AEC-Q101 is not mandated.
How does the SMB10J6.5-E3/52 differ from the SMBJ6.5A in terms of surge capability?
The SMB10J6.5-E3/52 delivers 1000 W peak pulse power (PPPM) versus 600 W for the SMBJ6.5A-reflecting a 67% higher energy-handling capacity. This difference stems from optimized chip geometry and thermal design, enabling the SMB10J6.5-E3/52 to withstand automotive load dump (ISO 7637-2) and industrial switching surges that would degrade or fail the SMBJ6.5A. Both share identical VWM and package.
What is the reverse leakage current specification for SMB10J6.5-E3/52 at its stand-off voltage?
At the 6.5 V stand-off voltage (VWM), the SMB10J6.5-E3/52 exhibits a maximum reverse leakage current (ID) of 1000 µA at 25 °C. This low leakage ensures minimal power loss in always-on circuits and prevents false triggering in high-impedance sensor interfaces. Leakage increases predictably with temperature but remains below 5000 µA at 125 °C per datasheet derating curves.
Can SMB10J6.5-E3/52 be used in bi-directional protection configurations?
No-SMB10J6.5-E3/52 is a unidirectional TVS diode, identified by its cathode band marking and specified breakdown behavior only in reverse bias. For bi-directional protection (e.g., AC lines or data buses), Vishay's SMB8J6.5CA or SMB10J6.5CA variants must be selected. Using SMB10J6.5-E3/52 in bi-directional roles risks forward conduction and failure during positive half-cycles.
