Product details
Overview
SMBG6.5C-E3/52 from Vishay General Semiconductor is a bi-directional transient voltage suppressor (TVS) diode in DO-215AA (SMBG) package, designed for clamping voltage transients on signal or 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, and 600 W peak pulse power rating with 10/1000 µs waveform - used to protect automotive sensor interfaces and industrial I/O circuits.
For engineers reviewing the SMBG6.5C-E3/52 datasheet, SMBG6.5C-E3/52 pinout, SMBG6.5C-E3/52 application, or SMBG6.5C-E3/52 equivalent, key selection criteria include bi-directional clamping capability, AEC-Q101 qualification, low clamping ratio (VC/VBR ≈ 1.48), RoHS-compliant matte tin terminations, and MSL Level 1 moisture sensitivity.
Technical Context
This bi-directional TVS diode operates symmetrically in both polarities, enabling protection of AC-coupled or differential signal lines without polarity constraints. Its glass-passivated junction ensures stable leakage (<1.0 µA at VWM) and fast response time (<1 ns), while the DO-215AA package supports automated SMT placement and meets UL 94 V-0 flammability.
Thermal performance is defined by RθJA = 100 °C/W and RθJL = 20 °C/W, with junction temperature rated from –55 °C to +150 °C. The device is rated for repetitive 600 W pulses at 0.01% duty cycle and complies with ANSI/IEEE C62.35 surge standards.
Key Specifications

|---|---|
| VWM | 6.5 V - Maximum continuous reverse operating voltage before clamping begins; sets safe margin below circuit operating voltage. |
| VBR (min/max) | 7.22 V / 7.98 V at 10 mA - Confirmed breakdown threshold range; ensures reliable turn-on during transients. |
| VC @ IPPM | 11.2 V at 53.6 A - Clamped voltage under 600 W 10/1000 µs surge; limits stress on downstream ICs. |
| PPPM | 600 W - Peak pulse power handling per single transient; validated per Fig. 1 derating curve. |
| ID @ VWM | ≤1.0 µA - Reverse leakage at stand-off voltage; ensures minimal power loss in standby. |

Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from ESD and load-dump transients in vehicle ECUs. IC Role / Device Role / Timing Role: Bi-directional voltage clamp placed between signal line and ground, responding within <1 ns to limit overvoltage. Use Value: Maintains signal integrity at 6.5 V nominal supply while clamping surges to ≤11.2 V, preventing damage to 5 V or 3.3 V interface ICs. |
Use Scenario: Safeguarding PLC digital input modules against field-wiring induced surges from relay coils or motor drives. IC Role / Device Role / Timing Role: Primary transient suppression element across input terminals, shunting surge energy to ground before reaching optocoupler or MCU GPIO. Use Value: Withstands 53.6 A peak current at 11.2 V clamping, ensuring immunity to IEC 61000-4-5 Level 3 (1 kV/2 kV) surges without degradation. |
| USB/Serial Data Line Protection | DC Power Rail Clamp |
|
Use Scenario: Shielding RS-485, RS-232, or USB 2.0 data lines in industrial gateways from ESD (±15 kV contact) and cable discharge events. IC Role / Device Role / Timing Role: Low-capacitance bi-directional TVS placed differentially across signal pairs, minimizing signal distortion. Use Value: Junction capacitance not specified but typical for SMBG family is <100 pF at 0 V; enables <100 Mbps operation without signal integrity loss. |
Use Scenario: Clamping 12 V or 24 V DC power rails in embedded controllers against load dump (ISO 7637-2 Pulse 5a) and jump-start transients. IC Role / Device Role / Timing Role: Secondary overvoltage clamp parallel to bulk capacitor, activated after primary fuse or polyfuse opens. Use Value: 600 W rating sustains multiple 100 ms transients up to 35 V, extending system uptime versus lower-power alternatives. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.5CA-E3/52 | Same VWM (6.5 V), identical DO-214AA (SMB) package but slightly higher VC (11.5 V @ 53.3 A); 600 W rating unchanged. | Lower thermal resistance (RθJA = 85 °C/W vs. 100 °C/W) improves power dissipation margin in compact layouts. | Select SMBJ6.5CA-E3/52 when board space allows SMB footprint and thermal headroom is constrained. |
| 1.5KE6.8CA | Higher power (1500 W), axial DO-201 package; VWM = 6.8 V, VC = 10.5 V @ 143 A - tighter clamping ratio but through-hole only. | Not suitable for automated SMT assembly; requires manual insertion and wave soldering. | Choose 1.5KE6.8CA only for legacy through-hole designs needing higher surge capacity and accepting larger footprint. |
Compared with SMBG6.5C-E3/52, SMBJ6.5CA-E3/52 offers better thermal performance in the same SMT form factor, while 1.5KE6.8CA trades mountability for higher surge robustness - making SMBG6.5C-E3/52 optimal for space-constrained, AEC-Q101-compliant SMT designs requiring precise 6.5 V clamping.

This eliminates risk of incorrect placement during SMT assembly.
Does SMBG6.5C-E3/52 meet automotive qualification standards?
Yes, SMBG6.5C-E3/52 is AEC-Q101 qualified per Vishay documentation (Document Number 88456, Revision 12-Nov-12). It undergoes stress testing including temperature cycling, high-temperature reverse bias (HTRB), and ESD per JS-001, confirming suitability for under-hood and chassis-mounted automotive electronics.
What is the maximum clamping voltage for SMBG6.5C-E3/52 under surge conditions?
The maximum clamping voltage (VC) for SMBG6.5C-E3/52 is 11.2 V at 53.6 A peak pulse current (IPPM) with a 10/1000 µs waveform. This value is measured per Figure 1 and Table on page 2 of the Vishay datasheet and defines the upper voltage limit imposed on protected circuitry during transient events.
Is SMBG6.5C-E3/52 RoHS-compliant and lead-free?
Yes, SMBG6.5C-E3/52 carries the "E3" suffix indicating RoHS-compliance per Directive 2011/65/EU, with matte tin-plated leads and halogen-free molding compound meeting JEDEC JS709A. It is rated for lead-free reflow with MSL Level 1 handling and 260 °C peak temperature per J-STD-020.
