App note: New family of 150V power schottky

App note from STMircoelectronics on the advantage of power schottky over bipolar diode in SMPS. Link here (PDF) Nowadays, the Switch Mode Power Supply (SMPS) is becoming more widespread as a result of computer, telecom and consumer applications. The constant increase in services (more peripherals) and performance, which offers us these applications, tends to move […]

App note: Using ESD diodes as voltage clamps

App note from Analog Devices on improving robustness of an amplifier by determining and mitigating internal ESD diode clamp electrical overestress. Link here When external overvoltage conditions are applied to an amplifier, ESD diodes are the last line of defense between your amplifier and electrical over stress. With proper understanding of how an ESD cell […]

Experimental Zener diode tester

Dilshan has published a new build: Automatic Zener diode tester is capable of identifying Zener diodes up to 27.5V. Apart from that, it can be used to recognize leads of the diodes/Zeners and detect damaged diodes. This tester is designed using well-known ICs such as MC34063 and PIC16F88. This unit provides approximately 5% to 15% […]

Single diode temperature sensor with Arduino ICU (& reverse-bias leakage)

Use a single diode as a temperature sensor with Arduino ICU Our LED light-sensing experiments lead to an interesting observation: When these loggers are left running overnight they still produce readings because reverse-bias ‘leakage-current’ eventually triggers the Interrupt Capture Unit (ICU) – in the absence of any light. The speed of this self-discharge depends on […]
