Product details
Overview
BZT585B7V5TQ-13 from Diodes Incorporated is a precision Zener diode in SOD523 package, rated for 7.5 V nominal breakdown voltage (±2.0% tolerance), 350 mW power dissipation, and AEC-Q101 qualified for automotive applications. It delivers stable voltage reference in low-power analog monitoring circuits, such as battery voltage supervision in infotainment control modules.
For engineers reviewing the BZT585B7V5TQ-13 datasheet, BZT585B7V5TQ-13 pinout, BZT585B7V5TQ-13 application, or BZT585B7V5TQ-13 equivalent, key selection criteria include Zener voltage accuracy, low dynamic impedance (10 Ω @ 5 mA), temperature coefficient (+3.8 mV/°C), and automotive-grade reliability under -65°C to +150°C operating range.
Technical Context
This Zener diode operates in reverse-biased breakdown mode to provide a stable reference voltage with tight 7.35–7.65 V tolerance at 5 mA test current. Its low 10 Ω Zener impedance at IZT ensures minimal output variation under load changes, while the +3.8 mV/°C temperature coefficient enables predictable drift compensation in temperature-sensitive designs.
The device uses a planar epitaxial construction in a molded plastic SOD523 package with matte tin–annealed Alloy 42 leads. It achieves 357 °C/W junction-to-ambient thermal resistance on FR-4 PCBs and supports ≤200 mA continuous forward current-enabling bidirectional protection and reference use in compact, high-reliability layouts.

FAQ
What is the maximum reverse voltage this Zener diode can withstand before breakdown?
The BZT585B7V5TQ-13 has a nominal Zener voltage of 7.5 V with a guaranteed range of 7.35–7.65 V at 5 mA test current. Breakdown occurs within this range under reverse bias; operation above 7.65 V may cause excessive power dissipation unless current is strictly limited by external series resistance.
Is this part suitable for use in high-temperature under-hood automotive applications?
Yes - it is AEC-Q101 qualified and rated for operation from -65°C to +150°C. Its +3.8 mV/°C temperature coefficient and stable 10 Ω Zener impedance at 5 mA ensure predictable performance in engine control units and transmission control modules exposed to sustained high ambient temperatures.
How does the SOD523 package affect thermal performance compared to larger packages?
The SOD523 package delivers 357 °C/W junction-to-ambient thermal resistance on standard FR-4 PCBs with minimum recommended pads. While smaller than SOD-123 or SOT-23, its flat-lead design and low mass enable rapid heat transfer - sufficient for ≤350 mW dissipation in thermally optimized layouts without heatsinking.
Can this Zener diode be used in forward-bias applications?
Yes - it supports up to 200 mA continuous forward current with 0.9 V typical forward voltage at 10 mA. Its low VF and robust construction allow dual use as both a forward rectifier in low-current paths and a reverse-bias voltage reference, simplifying BOM count in compact designs.
