In today’s electronics landscape, safeguarding sensitive circuits from voltage transients is critical. The SM6T10AHE3_B/H from Vishay’s TransZorb® series stands out as a high-performance, surface-mount TVS diode designed for automotive and telecom systems. With its 600W peak pulse power, AEC-Q101 qualification, and compact SMB package, this component addresses growing market demands for reliability in harsh environments. Discover how its advanced features can enhance your design’s resilience.
The SM6T10AHE3_B/H is a unidirectional Zener-based TVS diode in a DO-214AA (SMB) package, offering:
Peak Pulse Power: 600W (10/1000µs waveform)
Clamping Voltage: 14.5V max at 41A
Operating Temperature: -65°C to 150°C (TJ)
Automotive Compliance: AEC-Q101 qualified
| Parameter | Value | Standard |
|---|---|---|
| Reverse Standoff Voltage (VRWM) | 8.55V (Typ) | IEC 61000-4-5 |
| Breakdown Voltage (VBR) | ≥9.5V | MIL-STD-750 |
| Peak Pulse Current (IPP) | 41A | 10/1000µs waveform |
| Capacitance | Not specified | N/A |
Determine Voltage Requirements: Ensure VRWM exceeds the circuit’s operating voltage.
Assess Threat Levels: Match IPP and clamping voltage to expected transients.
Environmental Factors: For automotive use, verify AEC-Q101 compliance like the SM6T10AHE3_B/H.
Package Constraints: SMB packages (DO-214AA) suit space-limited designs.
Automotive Electronics: Protects ECUs, sensors, and infotainment systems from load-dump transients.
Telecom Equipment: Shields signal lines in base stations and routers.
Industrial Controls: Safeguards PLCs and motor drives.
According to MarketsandMarkets, the TVS diode market is projected to grow at 6.2% CAGR through 2027, driven by automotive electrification and 5G expansion. The SM6T series, with its automotive-grade options, is well-positioned to meet these demands.
| Model | VRWM | IPP | Package | Key Difference |
|---|---|---|---|---|
| SM6T10AHE3_B/H | 8.55V | 41A | SMB | AEC-Q101 qualified |
| P6SMB10A | 8.55V | 38.5A | SMB | Lower IPP |
| SMBJ10A | 8.55V | 24A | SMB | Non-automotive |
Yes, its 8.55V VRWM and 14.5V clamping voltage make it ideal for 12V bus protection.
While designed for larger transients, it can suppress ESD when used with complementary protection.
Enhances reliability by protecting the silicon junction from contaminants.
Unidirectional (like this model) protects against positive transients; bidirectional guards both polarities.
Yes, it meets MSL Level 1 (J-STD-020) with an LF peak of 260°C.
As vehicles adopt 48V architectures and telecom systems push higher frequencies, next-gen TVS diodes will require lower capacitance and higher power ratings. Vishay’s roadmap suggests continued innovation in these areas.
