Most engineers have faced this frustration: your product passes every functional test, but then fails again and again at the final ESD (electrostatic discharge) test. Or worse, a customer returns a device, and after investigation you realize the I/O chip was killed by a hot-plug surge or a random static zap. In many cases, the missing link is simply a solid TVS diode array—like SRV05-4.
📌SRV05-4: The “Invisible Bodyguard” for Your Design
Picture this: you’re designing a charging case for premium Bluetooth earbuds. That small USB-C port isn’t just a power input—it also handles firmware updates and data sync. But it’s fully exposed, making it the weakest entry point for ESD.
Here’s where SRV05-4 steps in. With response times in the nanosecond range, it clamps those surges to a safe level—around 12.5V at 1A or 17.5V at 5A.
Why does the 0.3pF junction capacitance is important? Because when you’re protecting high-speed signals like USB D+/D-, If the junction capacitance is too large, it will have a greater impact on the device data.Semiware's SRV05-4, the capacitance is so low you’ll barely notice it.
📌SRV05-4 can be used not only in consumer electronics, but also in industrial
Don’t think SRV05-4 is only for consumer gadgets. With an operating range from -55°C to +150°C, it’s also built for tougher environments.
Consider a factory floor, where PLC controllers connect to dozens of sensors and switches. Every time a motor starts or a relay clicks, strong transients and EMI ripple through the lines. Temperatures can spike too. In this setting, SRV05-4 can preventing system glitches or shutdowns. It’s the kind of invisible protection that ensures continuous, stable production.
📌Semiware's SRV05-4 can be used as a cost-effective alternative to Onsemi and Semtech
In recent years, many engineers learned the hard way that relying on a single supplier can stall a project when shortages hit. That’s why second-source compatibility is crucial.
Semiware's SRV05-4 is pin-compatible with Onsemi and Semtech, and the electrical characteristics are nearly identical:
- Reverse stand-off voltage (VRWM): 5V → Perfect for 3.3V and 5V systems
- Breakdown voltage (VBR): ~6V → Ensures solid blocking in normal operation
- Clamping voltage (VC): ~12.5V @1A, 17.5V @5A → Practically the same protection level
This means you can drop Semiware‘s SRV05-4 into the same SOT-23-6 footprint without redesigning your PCB. On your BOM, it works as both a cost-effective replacement and a secure second-source option.
🌈In general,Whether it's consumer electronics, networking equipment, or industrial equipment, Semiware's SRV05-4 can provide reliable circuit protection while controlling your BOM costs.
