Product details
Overview
BZX79-C3V6,113 from Nexperia is a ±5% tolerance Zener voltage regulator diode in a hermetically sealed SOD27 (DO-35) glass package, rated for 3.53–3.67 V nominal Zener voltage at 5 mA test current, 500 mW total power dissipation at Tamb = 50 °C, and 40 W non-repetitive peak reverse power. It serves as a low-power voltage reference in linear regulators and bias networks for analog sensor interfaces.
For engineers reviewing the BZX79-C3V6,113 datasheet, BZX79-C3V6,113 pinout, BZX79-C3V6,113 application, or BZX79-C3V6,113 equivalent, key selection criteria include Zener voltage tolerance, differential resistance (≤600 Ω), temperature coefficient (−3.5 to −2.4 mV/K), reverse leakage (≤5 μA at VR = 1 V), and thermal resistance (380 K/W junction-to-ambient).
Technical Context
This device operates in reverse breakdown mode with a specified Zener voltage defined at IZtest = 5 mA and Tj = 25 °C. Its differential resistance of ≤600 Ω at 5 mA determines regulation stiffness under load variation, while its negative temperature coefficient (−3.5 to −2.4 mV/K) enables predictable drift compensation in temperature-sensitive references.
The SOD27 axial-leaded glass package provides hermetic sealing and a cathode band marking, supporting manual or wave-solder assembly. Thermal performance is characterized by Rth j-a = 380 K/W (unmetallized PCB, max lead length), limiting continuous power handling to 400 mW at 50 °C ambient per derating curves.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 3.53–3.67 V at IZ = 5 mA; defines stable reference point for low-voltage biasing |
| Tolerance | ±5% (C-series); allows cost-effective use where tight regulation is not critical |
| Differential Resistance (rdif) | ≤600 Ω at IZ = 5 mA; limits output voltage shift under ±1 mA load change |
| Reverse Leakage (IR) | ≤5 μA at VR = 1 V; ensures minimal quiescent current in high-impedance reference nodes |
| Total Power Dissipation (Ptot) | 500 mW at Tamb = 50 °C; sets maximum continuous DC power in standard PCB mounting |
| Temperature Coefficient (SZ) | −3.5 to −2.4 mV/K at IZ = 5 mA; enables predictable thermal drift modeling in 0–70 °C range |
| Non-repetitive Peak Power (PZSM) | 40 W at tp = 100 μs; supports transient overvoltage clamping in surge-limited circuits |
Pinout & Package
Hermetically sealed SOD27 (DO-35) axial glass package with cathode identified by a colored band; leads are tinned copper alloy, suitable for hand soldering and wave soldering per J-STD-020.
| 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 / high-side connection in Zener configuration | Marked with band; connected to input voltage source to maintain regulated output at cathode |
Key Features
| Feature | Design Value |
|---|---|
| Low-cost ±5% Zener tolerance | Enables price-sensitive applications where 3.6 V ±0.18 V accuracy suffices (e.g., LED bias, microcontroller reset threshold) |
| Hermetic SOD27 glass package | Ensures long-term parameter stability and moisture resistance without conformal coating |
| 40 W non-repetitive surge rating | Provides transient overvoltage protection capability without external TVS in low-energy signal paths |
| Negative temperature coefficient | Allows predictable drift compensation when paired with positive-TC components (e.g., resistors) in reference dividers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4728A | 3.3 V nominal, ±5%, DO-41 package, 1 W Ptot, higher rdif (10 Ω typical) | Higher power handling but larger footprint; less stable at low currents due to higher IZK | Select when >500 mW continuous dissipation or higher surge immunity is required |
| BZX55-C3V6 | Same 3.6 V ±5%, DO-35 package, but 1.3 W Ptot and higher IZSM (10 A) | Superior surge robustness but wider VZ distribution (±5% vs tighter BZX79-B series) | Prefer for industrial environments with frequent ESD transients on supply lines |
Compared with 1N4728A and BZX55-C3V6, BZX79-C3V6,113 offers optimal balance of compact DO-35 form factor, proven long-term stability in hermetic glass, and sufficient surge margin for consumer-grade signal conditioning-without over-specifying power or cost.

FAQ
What is the maximum continuous Zener current for BZX79-C3V6,113 at 25 °C ambient?
The device supports up to 139 mA continuous Zener current at 25 °C ambient, calculated from Ptot = 500 mW and VZ ≈ 3.6 V. Derating begins above 50 °C ambient per the 380 K/W thermal resistance, reducing usable current to ~111 mA at 70 °C ambient.
Does BZX79-C3V6,113 have a specified Zener impedance curve?
Yes-differential resistance (rdif) is specified as ≤600 Ω at IZ = 5 mA and ≤90 Ω at IZ = 1 mA. The datasheet provides typical rdif vs. IZ curves showing decreasing impedance above 5 mA, reaching ~375 Ω at 10 mA.
Can BZX79-C3V6,113 be used in place of a BZX79-B3V6 for improved accuracy?
No-BZX79-B3V6 offers ±2% tolerance (3.53–3.67 V same as C-series, but tighter distribution), while BZX79-C3V6 has ±5% (3.4–3.8 V). Substituting introduces up to ±140 mV additional error in reference voltage, unacceptable in precision applications like ADC references.
Is the SOD27 package RoHS-compliant and lead-free?
Yes-the SOD27 package for BZX79-C3V6,113 uses lead-free tinning on copper alloy leads and complies with RoHS Directive 2011/65/EU. Nexperia confirms full compliance in product change notices dated 2018 and later, with no exemptions applied to this part number.
