Product details
Overview
BZX84C13_D87Z from ON Semiconductor is a 13 V ±5% Zener diode in SOT-23 package, rated for 250 mW power dissipation at 25°C ambient, with typical zener impedance of 15 Ω at 20 mA and reverse leakage current ≤0.1 µA at 8.0 V, used for voltage regulation and reference in low-power analog circuits.
For engineers reviewing the BZX84C13_D87Z datasheet, pinout, applications, or equivalent options, key selection criteria include zener voltage tolerance (±5%), thermal resistance (RJA = 465°C/W), junction temperature range (–55°C to +150°C), and low-capacitance operation (120 pF at 0 V) in compact SOT-23 footprint.
Technical Context
The BZX84C13_D87Z operates as a silicon planar epitaxial Zener diode optimized for stable voltage reference in biasing, overvoltage protection, and signal clamping applications. Its design supports precise DC regulation with minimal temperature drift (7.0 mV/°C at 5 mA) and low dynamic impedance across its operating current range (1–20 mA).
It features a cathode-anode polarity configuration with defined reverse-biased breakdown behavior, specified under steady-state thermal conditions on FR-4 PCB (76.2 mm × 114.3 mm). Forward voltage is capped at 0.9 V at 10 mA, ensuring predictable turn-on characteristics in dual-direction protection schemes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 12.4–14.1 V at IZ = 5 mA - defines nominal regulation point with ±5% tolerance band |
| Zener Impedance (ZZ) | 15 Ω max at IZ = 20 mA - ensures minimal output voltage variation under load transients |
| Power Dissipation (PD) | 250 mW at TA = 25°C - sets maximum continuous DC power handling on standard PCB |
| Junction-to-Ambient RJA | 465°C/W - determines thermal rise per watt; requires derating above 25°C ambient |
| Reverse Leakage (IR) | ≤0.1 µA at VR = 8.0 V - guarantees negligible standby current in high-impedance reference nodes |
| Capacitance (CJ) | 120 pF at VR = 0 V, f = 1 MHz - limits high-frequency noise coupling in RF-adjacent circuits |
| Tempco (dVZ/dT) | +7.0 mV/°C at IZ = 5 mA - quantifies voltage drift with temperature for precision reference designs |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5243B (ON Semi) | 13 V ±5%, 350 mW rating, SOT-23, ZZ = 17 Ω @ 20 mA | Higher power rating allows greater surge margin; slightly higher impedance affects regulation precision | Preferred when board-level transient energy exceeds 250 mW limits of BZX84C13_D87Z |
| BZX84-C13 (Nexperia) | 13 V ±5%, 300 mW, SOT-23, ZZ = 15 Ω @ 20 mA, IR = 0.1 µA @ 8 V | Identical electrical specs but different qualification grade (AEC-Q200 option available) | Selected for automotive-grade reliability where extended temperature validation is required |
Compared with MMBZ5243B and BZX84-C13, the BZX84C13_D87Z offers identical zener voltage and impedance but lower power rating (250 mW), making it optimal for space-constrained, low-power consumer and industrial control designs where thermal budget is tightly managed.

FAQ
What is the nominal zener voltage and tolerance of the BZX84C13_D87Z?
The BZX84C13_D87Z has a nominal zener voltage of 13 V with a tolerance of ±5%, meaning its actual breakdown voltage falls between 12.4 V and 14.1 V when tested at 5 mA. This specification is guaranteed across the full operating temperature range and forms the basis for its use in precision reference circuits. The BZX84C13_D87Z maintains this tolerance without requiring external calibration or trimming.
What is the maximum power dissipation rating for the BZX84C13_D87Z?
The BZX84C13_D87Z is rated for 250 mW power dissipation at an ambient temperature of 25°C when mounted on a standard FR-4 PCB (76.2 mm × 114.3 mm). Derating is required above 25°C at 0.54 mW/°C based on its 465°C/W junction-to-ambient thermal resistance. This rating directly limits usable current in continuous regulation applications. The BZX84C13_D87Z must not exceed this limit to ensure reliable long-term operation.
Does the BZX84C13_D87Z have a specified junction capacitance, and why does it matter?
Yes, the BZX84C13_D87Z has a junction capacitance of 120 pF measured at 0 V reverse bias and 1 MHz. This parameter is critical in high-frequency applications such as RF detectors or fast-switching clamps, where excessive capacitance can distort signal edges or attenuate high-frequency components. The BZX84C13_D87Z's relatively low CJ supports clean signal integrity in mixed-signal designs without requiring additional compensation.
How does temperature affect the zener voltage of the BZX84C13_D87Z?
The BZX84C13_D87Z exhibits a positive temperature coefficient of +7.0 mV/°C at 5 mA test current, meaning its zener voltage increases linearly with rising junction temperature. This behavior is well-characterized and enables predictable compensation in temperature-stable reference designs. Engineers using the BZX84C13_D87Z should account for this drift when designing circuits operating across wide ambient ranges, especially above 85°C.
What is the reverse leakage current specification for the BZX84C13_D87Z?
The BZX84C13_D87Z specifies a maximum reverse leakage current of 0.1 µA at a reverse voltage of 8.0 V and 25°C ambient. This ultra-low leakage ensures minimal parasitic current draw in high-impedance reference nodes or battery-powered systems. Because leakage rises exponentially with temperature and voltage, the BZX84C13_D87Z remains suitable for precision biasing even in thermally demanding environments when operated within its rated VR window.
