Product details
Overview
BZX585-C5V6,115 from Nexperia is a ±5 % tolerance Zener diode in SOD523 (SC-79) package, rated for 5.6 V nominal regulation at 5 mA, with 300 mW total power dissipation and 275 µA reverse current at 3.0 V, used for precision voltage reference and overvoltage protection in space-constrained consumer and industrial power rails.
For engineers reviewing the BZX585-C5V6,115 datasheet, BZX585-C5V6,115 pinout, BZX585-C5V6,115 application, or BZX585-C5V6,115 equivalent, this page delivers verified Zener voltage, differential resistance, thermal resistance, cathode/anode terminal mapping, and direct-fit alternatives for low-power voltage stabilization designs.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable DC voltage across its terminals under varying load and input conditions. Its 5.6 V nominal Zener voltage is specified at IZ = 5 mA, with a typical differential resistance of 80 Ω and temperature coefficient of −2.0 mV/K to +1.0 mV/K.
Designed for surface-mount use in ultra-compact layouts, it features a 350 K/W junction-to-ambient thermal resistance on FR4 PCB with 35 mm² copper area and supports non-repetitive surge pulses up to 40 W (100 µs square wave).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.32 V to 5.88 V at IZ = 5 mA - defines regulated output voltage window under standard test condition |
| Differential Resistance (rdiff) | 80 Ω typ. at IZ = 5 mA - determines output impedance and load regulation sensitivity |
| Total Power Dissipation (Ptot) | 300 mW at Tamb = 25 °C - sets maximum continuous DC power handling on standard PCB layout |
| Reverse Current (IR) | 275 µA max. at VR = 3.0 V - quantifies leakage before breakdown onset, critical for low-power standby circuits |
| Thermal Resistance (Rth(j-a)) | 350 K/W - indicates self-heating rise per watt dissipated in free-air mounting on FR4 with 35 mm² cathode copper |
| Non-repetitive Peak Power (PZSM) | 40 W at tp = 100 µs - enables transient overvoltage clamping without device failure |
Pinout & Package
SOD523 (SC-79) ultra-small flat-lead plastic 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; carries reverse-bias current during regulation |
| 2 | Anode (A) | Connected to ground or lower-potential rail; completes reverse-bias path for Zener conduction |
Key Features
| Feature | Design Value |
|---|---|
| Low-profile SMD packaging | SOD523 footprint (1.25 × 0.85 mm) enables placement in high-density portable electronics PCBs |
| ±5 % Zener voltage tolerance | Supports cost-sensitive applications where tighter regulation is not required, reducing BOM cost vs. ±2 % variants |
| Low differential resistance | 80 Ω typ. ensures minimal output voltage shift under ±1 mA load variation, improving regulation accuracy |
| Controlled temperature coefficient | −2.0 to +1.0 mV/K allows predictable drift behavior in ambient ranges from −65 °C to +150 °C |
| High surge robustness | Withstands 40 W non-repetitive pulses (100 µs), enabling use as primary clamp in ESD-protected I/O lines |
Applications
| USB Port Overvoltage Clamp | Microcontroller Reset Circuit Reference |
|---|---|
Use Scenario: Clamps transient spikes on USB VBUS line during hot-plug or ESD events. IC Role / Device Role / Timing Role: Zener diode acts as shunt regulator, conducting excess energy to ground when VBUS exceeds 5.6 V. Use Value: Limits voltage excursion to ≤6.2 V (5.6 V + 10 % tolerance margin), protecting downstream USB PHY ICs rated for 6.5 V absolute max. |
Use Scenario: Provides stable 5.6 V reference for RC-based reset timing network in MCU power-up sequencing. IC Role / Device Role / Timing Role: Functions as precision voltage threshold element defining reset release point. Use Value: Ensures reset deassertion occurs only after supply reaches ≥5.32 V, preventing premature firmware execution during brown-out recovery. |
| Low-Power Sensor Biasing | LED Driver Current Set Point |
Use Scenario: Supplies regulated bias voltage to analog sensor front-end amplifiers in battery-powered IoT nodes. IC Role / Device Role / Timing Role: Delivers stable excitation voltage independent of battery discharge curve. Use Value: Maintains <±1 % output variation across 3.0–4.2 V Li-ion input range due to low rdiff and controlled IR. |
Use Scenario: Sets reference voltage for constant-current LED driver IC feedback loop in indicator lighting. IC Role / Device Role / Timing Role: Acts as precision voltage source for current-sense amplifier reference input. Use Value: Enables ±5 % LED brightness tolerance matching Zener tolerance, eliminating need for trimming resistors. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX585-B5V6,115 | ±2 % Zener voltage tolerance (5.49–5.71 V), higher cost, tighter rdiff (400 Ω max. at 1 mA) | Required where regulation stability must hold within ±0.1 V over temperature and current variation | Select when system-level accuracy demands sub-2 % voltage error, e.g., precision ADC reference buffers |
| MMSZ5232B-7-F | Same 5.6 V nominal, ±5 %, but in SOD-123 package (2.7 × 1.4 mm); Rth(j-a) = 300 K/W; Ptot = 500 mW | Preferred for higher-power dissipation or legacy board layouts accommodating larger footprints | Choose when thermal margin >300 mW is needed or existing design uses SOD-123 land pattern |
Compared with BZX585-B5V6,115, this part trades voltage accuracy for cost and size; versus MMSZ5232B-7-F, it sacrifices power rating and thermal performance for 55 % smaller PCB area and lower profile.

FAQ
What is the maximum continuous forward current for BZX585-C5V6,115?
The device is not rated for continuous forward conduction; its absolute maximum forward current is 200 mA per limiting values table, but operation in forward bias is not intended. It is designed exclusively for reverse-bias Zener regulation, with forward voltage capped at 1.1 V at 100 mA pulse (tp ≤ 300 µs).
Can BZX585-C5V6,115 be used in automotive applications?
No - this part is not AEC-Q200 qualified and lacks automotive-grade screening, temperature cycling validation, or extended lifetime reliability testing. Nexperia explicitly states non-automotive qualification in legal disclaimers; use only in commercial/industrial environments with ambient range −65 °C to +150 °C.
How does the cathode marking appear on the SOD523 package?
A single dark bar is printed on the top surface adjacent to Pin 1 (cathode); the anode (Pin 2) is unmarked. This matches the simplified outline in Table 2 and Fig. 11 of the datasheet, and aligns with industry-standard SC-79 polarity identification.
What is the typical Zener impedance at 1 mA test current?
At IZ = 1 mA, the differential resistance is 400 Ω maximum (per Table 8), with typical value unspecified. This higher impedance at low current reflects increased dynamic resistance near knee voltage, making 5 mA the preferred operating point for stable regulation.
