Product details

Overview

BZX79-C5V6,113 from Nexperia is a ±5% tolerance Zener voltage regulator diode in a hermetically sealed SOD27 (DO-35) glass package, rated for 5.49 V to 5.71 V nominal Zener voltage at 5 mA test current, 80 Ω typical differential resistance, and −2.0 mV/K to +1.2 mV/K temperature coefficient. It delivers stable low-voltage reference or stabilization in power supply feedback paths, sensor biasing circuits, and overvoltage protection clamps.

For engineers reviewing the BZX79-C5V6,113 datasheet, BZX79-C5V6,113 pinout, BZX79-C5V6,113 application, or BZX79-C5V6,113 equivalent, this page provides verified electrical parameters, thermal behavior, real-world use cases, and validated alternative parts - all aligned with Nexperia's production-grade BZX79-C series specifications.

Technical Context

This Zener diode operates in reverse breakdown mode with a specified Zener voltage of 5.6 V (min 5.49 V, max 5.71 V) at I_Z = 5 mA, exhibiting low dynamic impedance (80 Ω typ., 400 Ω max) for tight regulation under varying load conditions. Its temperature coefficient ranges from −2.0 to +1.2 mV/K, enabling predictable drift compensation in precision analog references.

Designed for low-power stabilization, it supports continuous forward current up to 250 mA and non-repetitive peak reverse power dissipation of 40 W (100 μs pulse), with junction-to-ambient thermal resistance of 380 K/W on standard PCB mounting. Reverse leakage remains ≤1 μA at V_R = 2 V, ensuring minimal quiescent error in high-impedance bias networks.

Key Specifications

Parameter	Value and Actual Design Meaning
Zener Voltage (V_Z)	5.49 V to 5.71 V at I_Z = 5 mA - defines precise regulation point for 5.6 V nominal reference design
Differential Resistance (r_diff)	80 Ω typical, 400 Ω maximum - determines output voltage variation under load current changes
Temperature Coefficient (S_Z)	−2.0 to +1.2 mV/K - enables prediction and compensation of voltage drift across −65 °C to +200 °C operating range
Reverse Leakage Current (I_R)	≤1 μA at V_R = 2 V - ensures negligible error contribution in high-impedance voltage divider or reference nodes
Total Power Dissipation (P_tot)	500 mW at T_amb = 50 °C - sets maximum steady-state power handling on standard PCB without heatsinking
Junction-to-Ambient Thermal Resistance	380 K/W - quantifies self-heating impact; limits usable DC power to ~130 mW at 50 °C ambient for safe T_j < 150 °C

Pinout & Package

Hermetically sealed axial-leaded SOD27 (DO-35) glass package with cathode indicated by a colored band. Dimensions: D = 1.85 mm max, L = 25.4 mm min, b = 0.56 mm max. Lead spacing conforms to JEDEC DO-35 standard.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Forward conduction terminal / low-side connection in Zener configuration	Connected to ground or lower potential node when used as shunt regulator
Cathode	Reverse breakdown terminal / regulated output node	Connected to input voltage source via series resistor; provides stable 5.6 V reference at this node

Key Features

Feature	Design Value
±5% Zener voltage tolerance	Enables cost-optimized selection where tight regulation is not required, e.g., non-critical biasing or coarse overvoltage clamping
Hermetic glass SOD27 package	Ensures long-term stability and moisture resistance in industrial environments without conformal coating
40 W non-repetitive peak power rating	Supports transient surge suppression in low-energy protection circuits (e.g., ESD clamp before IC input)
Low 1 μA reverse leakage at 2 V	Minimizes loading error in high-resistance voltage dividers used for microcontroller ADC reference scaling

Applications

Use Scenario: Biasing a silicon photodiode in a smoke detector analog front-end.

IC Role / Device Role / Timing Role: Fixed-voltage node establishing reverse-bias potential across photodiode junction.

Use Value: Ensures consistent photocurrent response with <1 μA leakage preventing signal offset drift at high-impedance node.

Overvoltage Clamp for MCU I/O

Low-Power Voltage Monitor Threshold

Use Scenario: Protecting 5 V-tolerant GPIO pin against 12 V accidental connection during field service.

Equivalent & Alternatives

The following parts are listed as comparable options for similar Zener voltage reference applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BZX79-B5V6,113	±2% tolerance (5.50–5.70 V), lower r_diff (400 Ω max vs. 400 Ω), tighter tempco (−2.0 to +1.2 mV/K same)	Preferred where higher accuracy needed in voltage reference or feedback loops	Select for improved regulation accuracy at modest cost premium; same footprint and thermal profile
1N4734A	5.6 V nominal, ±5%, 1 W power rating, DO-41 package (larger, higher R_{th j-a} = 500 K/W)	Suitable for higher-power dissipation needs but requires PCB layout revision	Choose only if >500 mW continuous dissipation is required; otherwise SOD27 offers superior board density

Compared with BZX79-B5V6,113, this part trades 2% tolerance for lower cost and identical thermal performance; versus 1N4734A, it sacrifices power headroom for compact size and better thermal efficiency on dense PCBs.

FAQ

What is the maximum continuous power dissipation for BZX79-C5V6,113 at 50 °C ambient?

The device is rated for 500 mW total power dissipation at T_amb = 50 °C with leads mounted per standard PCB layout (no metallization pad, lead length ≤8 mm). Derating is required above 50 °C ambient using R_{th j-a} = 380 K/W - for example, max power drops to ~320 mW at 70 °C ambient.

Can BZX79-C5V6,113 be used as a replacement for BZX79-B5V6,113?

Yes, but with reduced voltage accuracy: BZX79-C5V6,113 has ±5% tolerance (5.2–6.0 V) versus ±2% (5.50–5.70 V) for the B variant. Differential resistance is higher (400 Ω max vs. 400 Ω max), and temperature coefficient spread is wider. Use only where looser regulation is acceptable.

What is the reverse leakage current specification at 2 V reverse bias?

Per the official Nexperia datasheet, reverse leakage current I_R is guaranteed ≤1 μA at V_R = 2 V and T_j = 25 °C. This value is confirmed in Table 1 for the BZX79-B/C5V6 type and applies identically to the C-series variant.

Is the SOD27 package compatible with automated through-hole assembly?

Yes - the SOD27 (DO-35) package features axial leads with standardized pitch and diameter compliant with IPC-7351 Class A requirements. It supports wave soldering, selective soldering, and hand-soldering; lead coplanarity and straightness meet Nexperia's production release specifications for high-yield insertion.
