Product details

Overview

BZX84-C13/LF1R from NXP Semiconductors is a ±5 % tolerance Zener voltage regulator diode in SOT23 (TO-236AB) package, rated for 13 V nominal breakdown voltage at 5 mA, 250 mW total power dissipation, and AEC-Q101 qualified for automotive use.

For engineers reviewing the BZX84-C13/LF1R datasheet, BZX84-C13/LF1R pinout, BZX84-C13/LF1R application, or BZX84-C13/LF1R equivalent, this page delivers verified specifications, validated SOT23 terminal mapping, confirmed automotive-grade reliability, and real-world regulation use cases - all grounded in NXP's Rev. 6 product data sheet.

Technical Context

The BZX84-C13/LF1R operates as a two-terminal shunt voltage reference, maintaining stable reverse-biased conduction above its 12.4–14.1 V breakdown range (±5 %). Its differential resistance of ≤170 Ω at I_Z = 5 mA ensures predictable regulation under load variation.

Designed for low-power stabilization, it supports non-repetitive peak reverse currents up to 2.5 A (100 µs pulse), exhibits a temperature coefficient of +7.0 to +11.0 mV/K, and achieves ≤0.1 µA reverse leakage at 10.4 V - enabling precision biasing in temperature-sensitive circuits.

Key Specifications

Nominal Zener Voltage	13 V at I_Z = 5 mA - defines primary regulation point for 12–14 V rail clamping
Voltage Tolerance	±5 % (12.4–14.1 V) - enables cost-effective selection where tight regulation is not critical
Total Power Dissipation	250 mW at T_amb ≤ 25 °C - sets maximum continuous DC power handling on standard FR4 PCB
Differential Resistance	≤170 Ω at I_Z = 5 mA - determines output impedance and load regulation error
Reverse Leakage Current	≤0.1 µA at V_R = 10.4 V - ensures minimal quiescent current in standby mode
Non-repetitive Peak Current	2.5 A (100 µs, square wave) - supports transient overvoltage suppression without failure
AEC-Q101 Qualified	Validated for automotive applications - meets stress test requirements for discrete semiconductors

FAQ

What is the exact Zener voltage range for BZX84-C13/LF1R?

The BZX84-C13/LF1R has a guaranteed breakdown voltage range of 12.4 V to 14.1 V at 5 mA test current, reflecting its ±5 % tolerance specification per NXP's Rev. 6 datasheet. This range remains valid across ambient temperatures from –65 °C to +150 °C, with temperature coefficient values documented from +7.0 to +11.0 mV/K.

Is BZX84-C13/LF1R suitable for automotive applications?

Yes, BZX84-C13/LF1R is AEC-Q101 qualified per NXP's official documentation, confirming its suitability for automotive applications including engine control modules, body control units, and infotainment power rails. The qualification covers stress testing for temperature cycling, humidity, and mechanical robustness required for under-hood deployment.

What is the maximum continuous power dissipation of BZX84-C13/LF1R?

BZX84-C13/LF1R has a total power dissipation limit of 250 mW at ambient temperatures ≤25 °C when mounted on a standard FR4 PCB with single-sided copper and tin-plated finish. Derating is required above 25 °C, with thermal resistance from junction to ambient specified at 500 K/W in free air.

Does BZX84-C13/LF1R have a connected pin 2?

No, pin 2 of BZX84-C13/LF1R is internally not connected (n.c.), as confirmed in Table 2 of NXP's datasheet. It must remain unconnected on the PCB layout - no trace, pad, or solder joint should be assigned to this terminal to avoid unintended parasitic coupling or mechanical stress.

What is the reverse leakage current specification for BZX84-C13/LF1R?

BZX84-C13/LF1R exhibits a maximum reverse leakage current of 0.1 µA at V_R = 10.4 V (80 % of nominal V_Z), measured at T_j = 25 °C. This low leakage supports ultra-low-power applications such as battery-backed sensors and always-on wake-up circuitry without compromising standby current budgets.
