Product details
Overview
BZX585-B6V2,135 from Nexperia is a ±2 % tolerance Zener diode in SOD523 (SC-79) package, rated for 6.2 V nominal regulation at 5 mA, with 40 Ω typical differential resistance and 300 mW total power dissipation. It delivers stable voltage reference and overvoltage clamping in space-constrained consumer and industrial power management circuits.
For engineers reviewing the BZX585-B6V2,135 datasheet, BZX585-B6V2,135 pinout, BZX585-B6V2,135 application, or BZX585-B6V2,135 equivalent, key selection criteria include Zener voltage tolerance, thermal resistance (65 K/W junction-to-solder-point), non-repetitive surge capability (40 W @ 100 µs), and SC-79 footprint compatibility with high-density PCB layouts.
Technical Context
This Zener diode operates in reverse breakdown to maintain a stable 6.2 V reference across load variations, with low dynamic impedance (40 Ω typ. at IZ = 5 mA) ensuring minimal output voltage drift under changing current conditions. Its temperature coefficient of +0.4 to +2.2 mV/K (typ.) supports predictable behavior across −65 °C to +150 °C junction temperatures.
The device uses planar epitaxial construction for consistent parametric performance and reliability. Its 2-pin SOD523 package features a cathode-marked end (bar) and is optimized for reflow soldering per JEDEC J-STD-020, with thermal resistance from junction to solder point specified at 65 K/W when mounted on FR4 with 35 mm² copper area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.08 V to 6.32 V at IZ = 5 mA - tight ±2 % tolerance enables precise voltage reference without trimming |
| Differential Resistance (rdiff) | 40 Ω typ. at IZ = 5 mA - low impedance minimizes regulation error under load transients |
| Total Power Dissipation (Ptot) | 300 mW at Tamb = 25 °C - defines continuous DC power handling on standard FR4 PCB |
| Non-repetitive Peak Power (PZSM) | 40 W @ tp = 100 µs - supports transient overvoltage suppression in ESD/surge events |
| Forward Voltage (VF) | 1.1 V max at IF = 100 mA - ensures low conduction loss when used as clamp in forward bias |
| Junction-to-Solder-Point Rth | 65 K/W - enables accurate thermal modeling for layout-dependent reliability in compact designs |
| Reverse Current (IR) | 3.0 µA max at VR = 4.5 V - guarantees low leakage in standby or precision 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 terminal 1.
| 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; forms reverse-biased junction during Zener operation |
Key Features
| Feature | Design Value |
|---|---|
| ±2 % Zener voltage tolerance | Enables direct replacement in precision reference circuits without calibration or resistor adjustment |
| 40 W non-repetitive peak power rating | Provides robust transient immunity against 100 µs surges without derating or external protection |
| 65 K/W junction-to-solder-point thermal resistance | Supports accurate thermal simulation for reliability validation in thermally dense layouts |
| Low 40 Ω differential resistance | Maintains regulation stability within ±25 mV over 1–10 mA Zener current variation |
| SOD523 footprint compatibility | Matches industry-standard SC-79 land pattern (JEDEC MO-203-AB), enabling drop-in placement on automated SMT lines |
Applications
| Power Supply Voltage Reference | ESD Protection Clamp |
|---|---|

Use Scenario: Providing stable 6.2 V reference for ADC biasing and op-amp feedback networks in battery-powered IoT sensors. IC Role / Device Role / Timing Role: Zener diode operating in reverse breakdown to fix reference node potential independent of supply ripple. Use Value: ±2 % tolerance and 40 Ω rdiff ensure reference accuracy remains within 0.124 V over 5–10 mA current range, reducing system calibration burden. |
Use Scenario: Clamping I/O line voltage during electrostatic discharge events on USB or GPIO interfaces. IC Role / Device Role / Timing Role: Fast-acting shunt element that conducts above 6.2 V to divert surge current away from sensitive IC inputs. Use Value: 40 W peak power rating at 100 µs allows absorption of IEC 61000-4-2 Level 4 (15 kV air) surges without degradation. |
| Low-Power Regulator Feedback | Overvoltage Detection Threshold |
|

IC Role / Device Role / Timing Role: Precision voltage divider component defining output setpoint via resistive network tied to regulator feedback pin. Use Value: Low 3.0 µA max reverse leakage at 4.5 V prevents loading of high-impedance feedback dividers, preserving regulation accuracy. |
Use Scenario: Triggering shutdown circuitry when input voltage exceeds safe operating limit in automotive accessory modules. IC Role / Device Role / Timing Role: Threshold detector whose conduction initiates comparator or microcontroller interrupt upon overvoltage condition. Use Value: +0.4 to +2.2 mV/K temperature coefficient enables predictable trip-point shift across −40 °C to +125 °C ambient, simplifying thermal compensation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5234BS-7-F | 6.2 V, ±5 % tolerance, SOT-323 package, 200 mW Ptot, 100 Ω rdiff | Higher leakage (5 µA @ 4.5 V), larger footprint, lower surge rating (25 W) | Select when cost sensitivity outweighs precision and surge robustness requirements |
| BZX384-B6V2 | 6.2 V, ±2 %, SOD-323 package, 300 mW Ptot, 60 Ω rdiff, 100 °C max Tj | Larger 1.7 mm × 1.25 mm footprint, higher thermal resistance (120 K/W), lower max junction temperature | Choose where board space permits larger package and thermal margin is less critical than ultra-miniaturization |
Compared with MMBZ5234BS-7-F and BZX384-B6V2, BZX585-B6V2,135 offers superior regulation precision (±2 %), lowest dynamic impedance (40 Ω), smallest footprint (SOD523), and highest surge resilience (40 W), making it optimal for miniaturized, high-reliability power control nodes.

FAQ
What is the maximum continuous Zener current for BZX585-B6V2,135 at 25 °C ambient?
The absolute maximum forward current is 200 mA, but continuous Zener operation is limited by power dissipation. At 25 °C ambient on FR4 with 35 mm² copper, the 300 mW Ptot rating allows up to 48.4 mA (300 mW ÷ 6.2 V) average Zener current before thermal derating applies.
Does BZX585-B6V2,135 meet lead-free and RoHS compliance requirements?
Yes, BZX585-B6V2,135 is manufactured using lead-free solderable terminations and complies with EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, with full material declarations available through Nexperia's product change notifications.
Can BZX585-B6V2,135 be used in series or parallel configurations?
Series connection is permissible for higher voltage references, provided matching tolerances and thermal coupling are managed. Parallel use is not recommended due to mismatched Zener knee characteristics, which cause current hogging and thermal runaway without individual ballast resistors.
How does the temperature coefficient affect regulation accuracy over −40 °C to +125 °C?
With a typical SZ of +0.4 to +2.2 mV/K, the Zener voltage increases by approximately 100 to 550 mV across this range. For applications requiring stable reference, this drift must be compensated in system-level calibration or mitigated using temperature-insensitive topologies like bandgap references.
