Product details
Overview
BZX585-C62,115 from Nexperia is a 62 V ±5 % tolerance Zener diode in SOD523 (SC-79) package, rated for 300 mW total power dissipation and 40 W non-repetitive peak reverse power, used for precision voltage regulation in space-constrained low-power circuits such as sensor biasing and reference voltage generation.
For engineers reviewing the BZX585-C62,115 datasheet, BZX585-C62,115 pinout, BZX585-C62,115 application, or BZX585-C62,115 equivalent, this page delivers verified Zener voltage, differential resistance, thermal resistance, cathode/anode terminal mapping, and real-world regulation use cases - all confirmed from Nexperia's Rev. 8 product data sheet dated 6 August 2026.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable 62 V regulation at IZ = 2 mA, with a typical differential resistance of 120 Ω and temperature coefficient of +64.4 mV/K - indicating positive drift over temperature, requiring compensation in high-stability references. Its ultra-small SOD523 footprint supports high-density PCB layouts where thermal mass is limited.
Designed for single-event transient suppression and DC voltage clamping, it sustains 40 W non-repetitive surges (tp = 100 µs, square wave) while maintaining junction temperature within −65 °C to +150 °C limits. Junction-to-solder-point thermal resistance is 65 K/W, enabling reliable operation on FR4 boards with minimal copper area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 62 V nominal, ±5 % tolerance at IZ = 2 mA - defines precise clamping level for overvoltage protection and reference circuits. |
| Differential Resistance (rdiff) | 120 Ω typical at IZ = 2 mA - determines regulation stiffness; lower values yield tighter voltage control under load variation. |
| Temperature Coefficient (SZ) | +64.4 mV/K at IZ = 2 mA - quantifies positive VZ drift with temperature, critical for ambient-compensated designs. |
| Total Power Dissipation (Ptot) | 300 mW at Tamb = 25 °C on FR4 with 35 mm² cathode copper - sets continuous DC power handling limit in standard mounting. |
| Non-repetitive Peak Power (PZSM) | 40 W for tp = 100 µs square wave - enables short-duration surge clamping without device failure. |
| Junction-to-Solder-Point Rth | 65 K/W - defines thermal path efficiency from die to PCB; guides layout for thermal reliability in compact assemblies. |
| Reverse Current (IR) | 0.05 µA max at VR = 49.6 V - ensures minimal leakage below breakdown, preserving accuracy in high-impedance bias networks. |
Pinout & Package
SOD523 (SC-79) ultra-small flat-lead surface-mount package: 1.25 mm × 0.85 mm body, 0.65 mm height, cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; marking bar identifies this terminal - reverse-biased during Zener operation. |
| 2 | Anode (A) | Connected to ground or lower-potential rail; completes current path during breakdown conduction. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-compact SOD523 package | Enables placement in <1.5 mm² board area - ideal for wearables, IoT sensors, and miniaturized power management modules. |
| ±5 % Zener voltage tolerance | Supports cost-sensitive applications where tight regulation is secondary to size and reliability - e.g., LED current setting or MCU supply rail clamping. |
| Low 120 Ω differential resistance | Minimizes output voltage shift under ±1 mA load change - improves stability in feedback loops and analog reference buffers. |
| 40 W non-repetitive surge rating | Withstands ESD and inductive kickback transients without degradation - eliminates need for external TVS in many low-energy interfaces. |
| −65 °C to +150 °C operating range | Validates use in industrial control, automotive under-hood modules (non-automotive qualified), and outdoor electronics with wide ambient swings. |
Applications
| Power Supply Rail Clamping | Sensor Bias Reference |
|---|---|
|
Use Scenario: Protecting 3.3 V or 5 V microcontroller I/O pins from accidental overvoltage during hot-plug or ESD events. IC Role / Device Role / Timing Role: Zener diode acts as shunt clamp, conducting excess current above its 62 V breakdown threshold to limit voltage swing on protected lines. Use Value: Prevents latch-up or gate oxide damage in downstream logic without adding series impedance - maintains signal integrity during fault conditions. |
Use Scenario: Providing stable bias voltage to MEMS pressure sensor bridge circuitry in battery-powered environmental monitors. IC Role / Device Role / Timing Role: Functions as passive voltage reference source, delivering fixed 62 V potential to excite high-impedance sensing elements. Use Value: Enables ratiometric measurement accuracy independent of supply fluctuations - critical for sub-1 % measurement repeatability. |
| ADC Reference Stabilization | LED Constant-Current Setpoint |
|
Use Scenario: Stabilizing reference input to 12-bit SAR ADC in portable medical diagnostic equipment. IC Role / Device Role / Timing Role: Zener establishes clean, low-noise reference voltage for ADC conversion - minimizing code spread due to supply ripple. Use Value: Reduces effective number of bits (ENOB) degradation by limiting reference drift to <0.5 LSB across 0–70 °C ambient range. |
Use Scenario: Setting precise current threshold in discrete LED driver stage for automotive interior lighting modules. IC Role / Device Role / Timing Role: Used in conjunction with current-sense resistor and transistor to define LED forward current via VZ/Rsense ratio. Use Value: Achieves ±5 % luminance consistency across production units without trimming - lowers manufacturing test time and cost. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX585-B62,115 | Same 62 V nominal voltage but ±2 % tolerance and higher differential resistance (105 Ω typ). | Better regulation accuracy at cost of slightly reduced surge robustness and higher tempco (+63.8 mV/K). | Select when tighter voltage tolerance outweighs need for lowest possible rdiff or highest surge margin. |
| MMSZ5262B-7-F | 62 V ±5 %, SOD-123 package (2.7 × 1.4 mm), 500 mW Ptot, rdiff = 110 Ω typ. | Larger footprint but higher continuous power rating - suitable for higher-current regulation or elevated ambient temperatures. | Choose when board space allows larger package and thermal design requires >300 mW steady-state dissipation. |
Compared with BZX585-C62,115, the BZX585-B62,115 offers tighter voltage control at the expense of surge margin, while MMSZ5262B-7-F trades miniaturization for higher thermal headroom - making the C-grade optimal for size- and surge-critical, moderate-power applications.

FAQ
What is the maximum continuous reverse current for BZX585-C62,115 at 25 °C?
The maximum continuous reverse current is derived from Ptot = 300 mW and VZ = 62 V, yielding IZ(max) ≈ 4.84 mA. This assumes no additional power loss from series resistance or ambient heating - actual design current should remain ≤3.5 mA for long-term reliability at full-rated ambient.
Can BZX585-C62,115 be used in automotive applications?
No - BZX585-C62,115 is not automotive-qualified per Nexperia's legal disclaimers. It lacks AEC-Q101 qualification, has no guaranteed performance over automotive temperature ranges (−40 °C to +125 °C), and is explicitly designated for industrial and consumer use only.
How does the cathode marking appear on the SOD523 package?
The cathode is identified by a visible bar printed on the top surface of the SOD523 package, aligned with Pin 1. The physical outline shows Pin 1 (cathode) on the left and Pin 2 (anode) on the right when the marking bar is oriented upward - matching Nexperia's simplified outline diagram in Figure 11.
What is the typical Zener voltage drift over temperature for this part?
At IZ = 2 mA, the temperature coefficient is +64.4 mV/K - meaning VZ increases by ~64.4 mV per Kelvin rise in junction temperature. Over a 100 K range (25 °C to 125 °C), this yields ~6.4 V total drift, requiring compensation in precision reference designs.
