Product details
Overview
BZX284-B13,115 from NXP Semiconductors is a ±2% tolerance Zener voltage regulator diode in SOD110 ceramic SMD package, rated for 13 V nominal working voltage at 5 mA test current, 400 mW total power dissipation, and 100 nA reverse leakage at 8 V reverse bias. It serves as a precision low-power voltage reference in power supply feedback paths, overvoltage protection circuits, and analog signal conditioning stages.
For engineers reviewing the BZX284-B13,115 datasheet, BZX284-B13,115 pinout, BZX284-B13,115 application, or BZX284-B13,115 equivalent, this page delivers verified electrical parameters, thermal behavior, package geometry, and real-world implementation guidance for stable voltage regulation in space-constrained PCB designs.
Technical Context
The BZX284-B13,115 operates as a two-terminal silicon Zener diode with controlled reverse breakdown at 12.7–13.3 V (±2%) under 5 mA test current. Its differential resistance is 25–170 Ω at 5 mA, and temperature coefficient is +2 mV/K at 5 mA - indicating positive drift above ~6 V, enabling predictable thermal compensation in reference circuits.
Designed for surface-mount use on standard FR-4 PCBs (11 × 25 × 1.6 mm), it exhibits 315 K/W junction-to-ambient thermal resistance and supports non-repetitive peak reverse currents up to 2.5 A for 100 μs surges, making it suitable for transient suppression in low-energy systems.

FAQ
What is the nominal Zener voltage and test condition for BZX284-B13,115?
The BZX284-B13,115 has a nominal Zener voltage of 13 V measured at a test current of 5 mA, with a guaranteed range of 12.7 V to 13.3 V (±2%). This specification is defined in Table 1 of the NXP datasheet and applies under Tj = 25 °C conditions. The BZX284-B13,115 maintains this regulation performance within its specified thermal and current operating envelope.
What is the maximum power dissipation of BZX284-B13,115 and under what conditions?
The BZX284-B13,115 has a maximum total power dissipation of 400 mW at ambient temperature of 25 °C when mounted on a standard 11 × 25 × 1.6 mm FR-4 PCB (per note 1 in Limiting Values). Derating is required above 25 °C at 1.27 mW/°C based on its 315 K/W junction-to-ambient thermal resistance. This rating applies to continuous DC operation, not transient surges.
How does the temperature coefficient of BZX284-B13,115 affect its regulation stability?
The BZX284-B13,115 exhibits a temperature coefficient of +2 mV/K at IZ = 5 mA, meaning its Zener voltage increases by approximately 2 mV per degree Celsius rise in junction temperature. This positive drift is typical for Zeners above 6 V and enables predictable thermal compensation when combined with negative-tempco components. The BZX284-B13,115's stable tempco supports accurate voltage references in environments with moderate temperature gradients.
What is the reverse leakage current specification for BZX284-B13,115 and at what voltage is it measured?
The BZX284-B13,115 has a maximum reverse leakage current of 100 nA measured at a reverse voltage of 8 V and Tamb = 25 °C. This value is specified in the Electrical Characteristics table under "IR" for BZX284-B/C13. Low leakage ensures minimal current draw in high-impedance bias networks and preserves accuracy in precision reference applications where the BZX284-B13,115 is deployed.
Which package type does BZX284-B13,115 use and what are its key mechanical dimensions?
The BZX284-B13,115 uses the SOD110 very small ceramic SMD package, with outline dimensions of 2.10 mm length × 1.40 mm width × 1.60 mm height. It features a cathode identifier mark on the top surface and is optimized for reflow soldering on standard PCBs. The SOD110 package provides superior moisture resistance and long-term parameter stability compared to plastic-bodied alternatives, making the BZX284-B13,115 suitable for demanding industrial environments.
