With stand-off voltages rated from 22 to 70 V, it is ideal to protect any type of sensitive circuit.
As many variations are described in ISO 7637-2 pulse 5a/5b and ISO 16750-2 – due to surge duration, serial resistance in the circuit and surge voltage range – the datasheet provides four curves to accurately define the surge characteristics and select the appropriate LDP01Y device.
The LDP01Y series is supplied in a D2PAK package.

Combining a low on-state resistance (down to 0.36 Ω in the TO-220 package) with low gate charge and input/output capacitances, they allow faster and more efficient switching in adapters, solar micro-inverters and lighting applications.

AEC-Q101-qualified ultrafast rectifiers for automotive and outdoor
electronics
Housed in the 1 mm thick SMBFlat package, ST’s automotive-qualified high-voltage ultrafast rectifiers are suited for miniature electronic control modules, power converters, and motor drives, in automotive applications and, thanks to a -40 °C +175 °C temperature range, also harsh-environment applications, like base stations and outdoor lighting.
Footprint compatible with, yet 60% thinner than the standard SMB package with current-rated from 1 A to 3 A, and a VRRM from 600 V to 1200 V, this new 10-rectifier range includes L devices optimized for low forward voltage (VF), and R devices optimized for reverse-recovery time (trr).
- Never lose track with ST’s smart real-time
vehicle positioning, navigation and tracking system
The STEVAL-IEG001V2 is a smart vehicle tracking system featuring a GPS module based on TESEO II for positioning, GSM/GPRS for location update and MEMS as anti-theft feature and vehicle crash detection (a log is stored in the microSD card and sent via SMS for black-box functionality).
Installed in the vehicle, the system consists of a unit built around an STM32 microcontroller and a remote web server application where vehicle status and movements are shown on a map.
Nowadays, the tracking system is a key component of vehicle telematics, both in public transportation units, fleets and individual cars.

automotive CAN bus keeps clamping voltage below 35V
The ESDCAN01-2BLY is the second version of ST’s ESD protection diode designed for circuit protection of automotive controller area network (CAN) bus lines.
It provides ESD circuit protection up to 30 kV (ISO 10605) and overvoltage protection against other automotive electrical surges such as ISO 7637-3 pulse 3a/3b.
With a rated stand-off voltage at 24 V, it maintains the maximum clamping voltage below 35 V when subjected to ISO 7637-3 pulse 3a/3b bursts. Housed in the SOT23 package, it features a 230-watt peak pulse power at 120 °C for protection in harsh environments.
