Product details
Overview
BZT52C6V2S-7-F from Diodes Incorporated is a surface-mount Zener diode with nominal 6.2 V zener voltage at 5 mA test current, 10 Ω maximum zener impedance at 5 mA, and 200 mW power dissipation in SOD323 package. It provides precise voltage regulation in low-power biasing and reference circuits for industrial sensors and portable power management.
For engineers reviewing the BZT52C6V2S-7-F datasheet, BZT52C6V2S-7-F pinout, BZT52C6V2S-7-F application, or BZT52C6V2S-7-F equivalent, key selection criteria include zener voltage tolerance (±6.5% at 6.2 V), low dynamic impedance, AEC-Q101 qualification, and SOD323 thermal performance under ambient conditions up to +150°C.
Technical Context
This Zener diode operates in reverse breakdown mode with a specified zener voltage range of 5.8 V to 6.6 V at IZT = 5 mA and exhibits a temperature coefficient of +0.4 mV/°C. Its low 10 Ω zener impedance ensures stable regulation under varying load currents.
The device uses planar die construction in a molded plastic SOD323 case rated UL 94V-0, with matte tin-plated alloy 42 leads and cathode band polarity marking. Moisture sensitivity level is J-STD-020 Level 1, supporting standard reflow profiles without preconditioning.

FAQ
What is the maximum reverse current at 4.0 V for BZT52C6V2S-7-F?
The maximum reverse current (IR) is 2 µA at VR = 4.0 V, measured per DS30093 Rev. 20–2. This low leakage ensures minimal power loss in standby bias networks and supports accurate low-current sensing applications.
Is BZT52C6V2S-7-F suitable for automotive applications?
Yes - it is qualified to AEC-Q101 standards, including stress tests for temperature cycling, high-temperature reverse bias, and humidity testing. Its −65°C to +150°C operating range and SOD323 package meet requirements for under-hood and cabin ECU modules.
How does the 10 Ω zener impedance affect circuit performance?
A 10 Ω maximum zener impedance at 5 mA means the output voltage varies by ≤50 mV for a 5 mA load change. This enables stable regulation in feedback networks for op-amps and voltage references where tight tolerance is critical.
What is the thermal resistance of BZT52C6V2S-7-F on a standard FR-4 PCB?
The junction-to-ambient thermal resistance (RθJA) is 625 °C/W when mounted on an FR-4 board using Diodes Incorporated's recommended pad layout. This value assumes no copper pour or thermal vias; adding thermal relief improves heat dissipation.
