Product details
Overview
BZT52C13LPQ-7B from Diodes Incorporated is a surface-mount Zener diode with nominal 13 V zener voltage (12.4–14.1 V range), 5 mA test current, 30 Ω maximum zener impedance at IZT, 0.1 µA maximum reverse leakage at 8.0 V, and AEC-Q101 qualification for automotive use.
For engineers reviewing the BZT52C13LPQ-7B datasheet, BZT52C13LPQ-7B pinout, BZT52C13LPQ-7B application, or BZT52C13LPQ-7B equivalent, key selection criteria include zener voltage tolerance, thermal derating behavior, DFN1006 package solderability, and automotive-grade reliability validation under IATF16949.
Technical Context
This device operates as a precision voltage reference and overvoltage clamp in low-power analog and power-supply feedback paths. It delivers stable regulation at 5 mA test current with ±4.3% nominal voltage tolerance and exhibits a positive temperature coefficient of +7.0 to +11.0 mV/°C.
The X1-DFN1006-2 package enables high-density PCB layout and automated placement, while its NiPdAu-plated copper leadframe ensures robust solder joint integrity per MIL-STD-202, Method 208, and moisture sensitivity level 1 compliance per J-STD-020.

FAQ
What is the maximum power dissipation of BZT52C13LPQ-7B at 85°C ambient?
At 85°C ambient, the device's power dissipation must be derated linearly from 250 mW at 25°C using the 500 °C/W RθJA. The allowable power is 250 mW × (1 − (85 − 25)/500) = 130 mW. This assumes minimum recommended pad layout per Diodes' Suggested Pad Layout document.
Is BZT52C13LPQ-7B suitable for bidirectional ESD protection?
No - it is a unidirectional Zener diode optimized for reverse-bias regulation and forward-bias clamping. Its 0.9 V forward voltage and asymmetric IV curve make it unsuitable as a symmetric TVS device. For bidirectional ESD protection, dedicated TVS arrays like D24Z3.3M2LP should be used instead.
How does the temperature coefficient affect regulation accuracy over temperature?
With a +7.0 to +11.0 mV/°C coefficient, the zener voltage increases ~0.9–1.4 V from –40°C to +125°C. At 13 V nominal, this yields ~7–11% drift. For tighter stability, designers pair it with negative-TC components or use it in compensated reference topologies rather than standalone regulation.
Can BZT52C13LPQ-7B be hand-soldered reliably?
Yes - its X1-DFN1006-2 package supports hand soldering using fine-tip irons (≤0.5 mm tip) and flux-core solder, provided the cathode bar is clearly visible for orientation. Pre-tinning pads and controlled heat application (<3 seconds at 350°C) prevent lifting or tombstoning due to its 0.001 g mass and thermal asymmetry.
