ZXTR21xxFQ Automotive-Grade Regulator Transistors

Diodes' ZXTR21xxFQ are regulator transistors, qualified to AEC-Q101 standards for high reliability, and are PPAP capable. Designed to deliver 5 V, 8 V, or 12 V regulated outputs from nominal battery supplies of 12 V or 24 V, they are ideal for powering vehicle electronics as they can tolerate battery voltage spikes up to 60 V where standard linear regulators cannot be used. The devices’ 60 V maximum input rating ensures sufficient headroom in the event of transient overvoltage conditions while their excellent line-and-load regulation safeguards continuous operation by ensuring transient voltage drops cannot cause latch-up, further contributing to system reliability.

Features

• Smaller footprint
  • Monolithically integrating a transistor, Zener diode, and resistor into a SOT23 to reduce footprint while increasing power density and reliability
• 5 V ±5% / 8 V ±10% / 12 V ±10% V_OUT
  • Delivers 5 V, 8 V, or 12 V regulated outputs from nominal battery supplies of 12 V or 24 V, while also 60 V input capable in the event of overvoltage

Applications

• Supply voltage regulation in
  • 12 V to 5 V rails
  • 24 V to 5 V/8 V/12 V rails
