Product details
Overview
BZX585-C6V2,115 from Nexperia is a 6.2 V ±5 % Zener voltage regulator diode in SOD523 (SC-79) package, rated for 300 mW total power dissipation and 40 W non-repetitive peak reverse power, used for precision low-power voltage reference and overvoltage clamping in space-constrained consumer and industrial circuits.
For engineers reviewing the BZX585-C6V2,115 datasheet, BZX585-C6V2,115 pinout, BZX585-C6V2,115 application, or BZX585-C6V2,115 equivalent, key selection criteria include Zener voltage tolerance (±5 %), differential resistance (40 Ω at IZ = 5 mA), thermal resistance (65 K/W junction-to-solder point), and ultra-small SOD523 footprint compatibility with high-density PCB layouts.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable 6.2 V regulation across 1–5 mA test currents, with low 40 Ω differential resistance ensuring minimal voltage shift under load variation. Its temperature coefficient of +0.4 to +2.2 mV/K at IZ = 5 mA enables predictable drift behavior in ambient ranges from −65 °C to +150 °C.
The device supports transient suppression via 40 W non-repetitive peak reverse power handling (100 µs square wave, Tj = 25 °C), while its 300 mW steady-state dissipation is validated on FR4 PCB with 35 mm² copper area at cathode tab - critical for thermal reliability in compact designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.89 V to 6.51 V at IZ = 5 mA - defines regulation window for stable reference in low-current bias networks |
| Tolerance | ±5 % - specifies maximum deviation from nominal 6.2 V, enabling cost-effective selection where tight regulation suffices |
| Differential Resistance (rdiff) | 40 Ω (typ) at IZ = 5 mA - determines output impedance and load-induced voltage error in shunt regulator configurations |
| Total Power Dissipation (Ptot) | 300 mW at Tamb = 25 °C on FR4 with 35 mm² cathode copper - sets continuous operating limit for thermal design |
| Non-repetitive Peak Power (PZSM) | 40 W for 100 µs square wave - supports short-duration surge clamping without degradation |
| Forward Voltage (VF) | 1.1 V at IF = 100 mA - relevant for polarity protection or series forward-bias use cases |
| Junction-to-Solder-Point Rth | 65 K/W - quantifies thermal path efficiency from die to PCB, guiding copper pour sizing for thermal management |
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 for correct PCB orientation |
| 2 | Anode (A) | Connected to ground or lower-potential rail; completes reverse-bias path during Zener operation |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-compact SOD523 footprint | Enables placement in <1.5 mm² board area - ideal for wearables, IoT sensors, and miniaturized power rails |
| Low differential resistance | 40 Ω typical ensures <±25 mV output shift across 1–5 mA load current variation in shunt references |
| Controlled temperature coefficient | +0.4 to +2.2 mV/K allows predictable, low-drift behavior in ambient temperatures up to +150 °C |
| High surge robustness | 40 W non-repetitive peak power rating supports ESD and transient suppression per IEC 61000-4-2 Level 4 |
| Two-tolerance option | ±5 % grade balances cost and performance for general-purpose regulation where ±2 % is unnecessary |
Applications
| USB Port Overvoltage Protection | Low-Power Sensor Reference |
|---|---|
Use Scenario: Clamping 5 V USB supply against accidental 12 V misconnection or inductive kickback. IC Role / Device Role / Timing Role: Zener diode acts as shunt clamp, diverting excess current to ground when reverse voltage exceeds 6.2 V. Use Value: Prevents damage to downstream USB PHY ICs by limiting voltage to ≤6.51 V with <100 ns response, leveraging 40 W surge capability. |
Use Scenario: Providing stable 6.2 V reference for 12-bit ADC biasing in battery-powered environmental sensors. IC Role / Device Role / Timing Role: Functions as passive voltage reference in high-impedance divider network feeding ADC input. Use Value: Delivers <±31 mV regulation error (±5 % of 6.2 V) and <±11 mV tempco drift over −40 to +85 °C, meeting sensor accuracy requirements. |
| Microcontroller Reset Circuit | LED Current Regulation |
Use Scenario: Generating precise reset threshold for 3.3 V microcontrollers using resistor-Zener divider. IC Role / Device Role / Timing Role: Sets reliable 2.5 V reset trigger point via resistive divider from 5 V rail. Use Value: Enables clean reset assertion with <±0.13 V tolerance margin, supported by low 40 Ω rdiff minimizing divider loading error. |
Use Scenario: Stabilizing current through indicator LEDs in portable medical devices. IC Role / Device Role / Timing Role: Used in series with LED to fix forward voltage drop and improve current consistency. Use Value: Reduces LED brightness variation to <±8 % across 2.7–5.5 V supply range, leveraging tight 6.2 V Zener control. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX585-B6V2,115 | ±2 % tolerance (5.94–6.06 V vs. 5.89–6.51 V), higher cost, identical SOD523 package and power ratings | Required where tighter regulation is needed for precision analog circuits or calibration references | Select when ±2 % tolerance justifies premium pricing; otherwise BZX585-C6V2,115 offers optimal cost-performance balance |
| MMSZ5234B-7-F | 6.2 V ±5 %, SOD-123 package (2.7 × 1.4 mm), 500 mW Ptot, higher thermal resistance (250 K/W j-a) | Suitable for less space-constrained boards needing higher continuous power handling | Choose only if board layout permits larger footprint and thermal design accommodates higher Rth(j-a) |
Compared with BZX585-B6V2,115, the C-grade trades tighter tolerance for lower cost and same form factor; versus MMSZ5234B-7-F, it sacrifices 200 mW steady-state headroom for 45 % smaller PCB area and 2.7× better junction-to-solder thermal coupling.

FAQ
What is the maximum continuous reverse current for BZX585-C6V2,115 at 25 °C?
The maximum continuous reverse current is derived from Ptot = 300 mW and VZ ≈ 6.2 V, yielding IZ(max) ≈ 48 mA. This assumes no additional power loss from series resistance and full thermal derating above 25 °C ambient.
Can BZX585-C6V2,115 be used in automotive applications?
No - Nexperia does not qualify the BZX585 series for automotive use. It lacks AEC-Q200 stress testing, extended temperature validation beyond −65 °C to +150 °C, and automotive-specific reliability screening required for vehicle systems.
How is the cathode identified on the SOD523 package?
The cathode is marked by a visible bar on the top surface of the SOD523 package, aligned with Pin 1 per the simplified outline in Figure 11 of the datasheet. This matches the "K" designation in Table 2 pinning information.
What is the typical reverse leakage current at 4 V for BZX585-C6V2,115?
At VR = 4 V and Tj = 25 °C, typical reverse leakage is <0.1 µA, based on Fig. 8's curve for BZX585-C6V2. This low IR ensures minimal quiescent current draw in always-on reference circuits.
