Product details
Overview
PD3Z284C24Q-7 from Diodes Incorporated is an AEC-Q101 qualified 24 V, 5 mA Zener diode in PowerDI323 (Type B) package, with 30 Ω maximum Zener impedance at 5 mA, 0.1 µA maximum reverse leakage at 16.8 V, and ±5% voltage tolerance (22.8–25.6 V). It provides precision voltage regulation in automotive power supply monitoring circuits.
For engineers reviewing the PD3Z284C24Q-7 datasheet, PD3Z284C24Q-7 pinout, PD3Z284C24Q-7 application, or PD3Z284C24Q-7 equivalent, key selection criteria include Zener voltage accuracy, low thermal resistance (250 °C/W), AEC-Q101 qualification, IATF 16949 manufacturing, and compatibility with high-reliability automotive voltage reference and overvoltage clamp designs.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable reference voltage under varying load and temperature conditions. Its planar die construction ensures consistent breakdown characteristics, while the PowerDI323 (Type B) package enables high thermal efficiency on standard PCB layouts.
It delivers 500 mW power dissipation at 25 °C ambient, derating linearly above 25 °C per the published curve, and exhibits a positive temperature coefficient of +18.4 to +22.0 mV/°C at 5 mA test current - enabling predictable drift compensation in multi-device bias networks.

FAQ
What is the maximum operating junction temperature for PD3Z284C24Q-7?
The maximum operating junction temperature is +150 °C, with storage temperature also rated from –65 °C to +150 °C. Derating begins at 25 °C ambient per the published power derating curve, reaching zero dissipation at approximately +150 °C ambient on standard FR-4 board.
Is PD3Z284C24Q-7 compatible with lead-free reflow soldering processes?
Yes - it is fully RoHS 3 compliant and qualified for lead-free reflow per JEDEC J-STD-020 moisture sensitivity level 1. The matte tin–annealed copper leadframe ensures reliable solderability using standard SnAgCu profiles with peak temperatures up to 260 °C.
Does PD3Z284C24Q-7 have a specified capacitance value?
No specific capacitance value is provided in the datasheet for PD3Z284C24Q-7. However, Figure 4 shows total capacitance versus nominal Zener voltage, estimating ~15–20 pF at 24 V for this family - typical for low-current Zeners in PowerDI323 packages.
Can PD3Z284C24Q-7 be used in parallel for higher power handling?
No - Zener diodes exhibit negative temperature coefficients and mismatched breakdown voltages, causing current hogging when paralleled. For higher power, use a single higher-rated device or external active regulation; do not parallel PD3Z284C24Q-7 units.
