Product details
Overview
BZT52C16LP-7 from Diodes Incorporated is a surface-mount Zener diode with nominal zener voltage 16 V, ±5% tolerance (15.3–17.1 V), 40 Ω maximum zener impedance at 5 mA, and 250 mW power dissipation in DFN1006-2 package. It provides precision voltage regulation and overvoltage protection in space-constrained DC power rails for automotive body electronics, industrial sensor interfaces, and portable battery management circuits.
For engineers reviewing the BZT52C16LP-7 datasheet, BZT52C16LP-7 pinout, BZT52C16LP-7 application, or BZT52C16LP-7 equivalent, key selection criteria include zener voltage accuracy at 5 mA test current, thermal resistance (500 °C/W), cathode-marked DFN1006-2 footprint compatibility, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This device operates as a two-terminal voltage reference and clamp, leveraging silicon PN junction avalanche breakdown. Its zener voltage exhibits a +10.4 mV/°C temperature coefficient above 6 V, enabling predictable drift compensation in bias networks.
Designed for low-power stabilization, it delivers stable regulation under reverse-biased conditions with 0.1 µA maximum reverse leakage at 11.2 V and supports pulsed forward conduction up to 0.9 V at 10 mA without degradation.
Key Specifications

FAQ
What is the maximum reverse voltage this diode can withstand before breakdown?
The BZT52C16LP-7 has a nominal zener voltage of 16 V with a guaranteed range of 15.3–17.1 V at 5 mA test current. Breakdown occurs within this range under reverse bias; operation above 17.1 V risks exceeding specified parameters and potential degradation.
Is this part suitable for use in automotive under-hood applications?
Yes - BZT52C16LP-7 is qualified to AEC-Q101 standards, including temperature cycling, humidity testing, and mechanical shock. Its operating temperature range of –65°C to +150°C and DFN1006-2 package with NiPdAu terminations meet automotive under-hood reliability requirements.
How does the temperature coefficient affect regulation accuracy over temperature?
With a +10.4 mV/°C temperature coefficient, the zener voltage increases by approximately 1.04 V over a 100°C rise. For example, at +125°C ambient, VZ shifts to ~17.1 V - within its max specification, enabling predictable design margining in thermal-aware circuits.
Can this diode be used in forward-bias mode as a regular rectifier?
It is not optimized for forward conduction. While it conducts 10 mA at 0.9 V, its forward characteristics are secondary; the device is characterized and qualified for reverse-bias zener operation. Use dedicated signal diodes like 1N4148 for rectification tasks.
