Product details
Overview
BZX585-C6V2,135 from Nexperia is a Zener voltage regulator diode in SOD523 (SC-79) package, designed for precision low-power voltage reference and overvoltage protection in space-constrained circuits. It delivers a nominal 6.2 V regulation at 5 mA with ±5 % tolerance, 40 Ω typical differential resistance, and operates up to 300 mW total power dissipation - suitable for biasing, signal clamping, and power rail stabilization in portable sensor nodes.
For engineers reviewing the BZX585-C6V2,135 datasheet, BZX585-C6V2,135 pinout, BZX585-C6V2,135 application, or BZX585-C6V2,135 equivalent, key selection criteria include its 6.2 V Zener voltage with ±5 % tolerance, ultra-small SOD523 footprint, 40 Ω dynamic impedance at 5 mA, and non-repetitive surge capability of 40 W (100 µs pulse), critical for transient suppression in battery-powered IoT endpoints.
Technical Context
This Zener diode operates in reverse breakdown mode with a specified Zener voltage of 5.89 V (min) to 6.51 V (max) at IZ = 5 mA, exhibiting a positive temperature coefficient of +0.4 to +2.2 mV/K across that current range. Its low 40 Ω typical differential resistance ensures stable regulation under small load variations.
The device uses a planar silicon junction structure optimized for tight voltage tolerance and low capacitance (3.0 pF at 0 V, 1 MHz), enabling use in high-frequency reference and noise-sensitive analog front-ends. Thermal resistance from junction to solder point is 65 K/W, supporting reliable operation on FR4 PCBs with minimal copper area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.89 V to 6.51 V at IZ = 5 mA - defines precise regulation window for 6.2 V nominal rail |
| Tolerance | ±5 % - enables cost-effective selection where tighter tolerance is not required |
| Differential Resistance (rdiff) | 40 Ω typ. at IZ = 5 mA - ensures <10 mV output shift per 0.25 mA load change |

| Non-repetitive Peak Power (PZSM) | 40 W at tp = 100 µs - provides robust ESD/surge immunity per IEC 61000-4-2 Level 4 |
| Reverse Current (IR) | ≤ 3.0 µA at VR = 4.0 V - guarantees low leakage in standby-battery applications |
| Capacitance (Cd) | 3.0 pF at VR = 0 V, f = 1 MHz - minimizes signal coupling in RF-adjacent bias networks |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX585-B6V2,135 | ±2 % tolerance (vs. ±5 %); identical package, VZ min/max tighter (6.08–6.32 V) | Required where reference stability >0.1 % is needed across temperature and aging | Select when higher initial accuracy justifies premium cost and tighter inventory control |
| MMSZ5234B-7-F | Same 6.2 V nominal, ±5 %, but SOD-123 package (2.7 × 1.4 mm) and 500 mW Ptot | Better thermal performance in high-ambient environments; larger footprint limits ultra-dense layouts | Choose for industrial designs needing higher continuous power margin and legacy footprint compatibility |
Compared with BZX585-B6V2,135, the C-series offers relaxed tolerance for cost-sensitive volume production; versus MMSZ5234B-7-F, it trades thermal headroom for 55 % smaller board area - making it optimal for consumer wearables where size dominates reliability trade-offs.

FAQ
What is the maximum continuous reverse current the BZX585-C6V2,135 can sustain?
The device supports a maximum forward current of 200 mA per Absolute Maximum Ratings, but as a Zener diode, its continuous reverse (Zener) current is limited by power dissipation. At 25 °C ambient on FR4 with 35 mm² copper, 300 mW Ptot allows ~48 mA average Zener current (300 mW ÷ 6.2 V), assuming no additional thermal derating.
Does the BZX585-C6V2,135 require a series current-limiting resistor in standard regulation use?
Yes - a series resistor is mandatory to limit Zener current and prevent thermal runaway. For example, regulating from a 12 V supply to 6.2 V at 5 mA requires (12 V − 6.2 V) ÷ 5 mA = 1.16 kΩ. The resistor value must be selected based on worst-case input voltage, load current, and desired Zener bias current.
How does the temperature coefficient affect regulation accuracy over −40 °C to +125 °C?
At IZ = 5 mA, the BZX585-C6V2 exhibits a temperature coefficient of +0.4 to +2.2 mV/K. Over a 165 °C range, this introduces a potential VZ shift of +0.07 V to +0.36 V - meaning actual regulation may vary from 5.96 V to 6.87 V depending on operating point and thermal history.
Can the BZX585-C6V2,135 be used in place of a 6.2 V TL431 shunt regulator?
No - the BZX585-C6V2 is a passive two-terminal Zener diode with fixed breakdown voltage and no internal amplification or adjustable feedback. Unlike the TL431, it cannot provide programmable reference, sink current beyond its Zener rating, or maintain regulation under variable load without external buffering.
