Product details

Overview

BZX79-C7V5,113 from Nexperia is a ±5% tolerance Zener voltage regulator diode in a hermetically sealed SOD27 (DO-35) glass package, rated for 7.5 V nominal Zener voltage at 5 mA test current, 500 mW total power dissipation at 50 °C ambient, and 1 μA reverse leakage at 5 V. It serves as a low-power voltage reference in analog signal conditioning, power supply feedback networks, and overvoltage protection circuits.

For engineers reviewing the BZX79-C7V5,113 datasheet, BZX79-C7V5,113 pinout, BZX79-C7V5,113 application, or BZX79-C7V5,113 equivalent, this page delivers verified electrical parameters, thermal behavior, differential resistance, temperature coefficient, and real-world design implications - all specific to the C-series ±5% tolerance variant in DO-35 packaging.

Technical Context

This Zener diode operates in reverse breakdown mode with a specified Zener voltage of 7.35–7.65 V at I_Z = 5 mA, exhibiting a typical differential resistance of 30–80 Ω and a positive temperature coefficient of +2.5 to +5.3 mV/K. Its junction-to-ambient thermal resistance is 380 K/W under standard PCB mounting conditions.

Designed for stable DC voltage referencing, it supports non-repetitive surge handling up to 40 W for 100 μs pulses and maintains ≤1 μA reverse current at VR = 5 V, enabling precision biasing in low-current analog stages without significant loading error.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
1N4733A	Same 5% tolerance and 5.1 V rating but TO-92 plastic package; higher R_{th j-a} (500 K/W)	Limited to lower ambient temperatures due to reduced thermal performance	Select when cost is critical and board space allows larger footprint
BZX55C7V5	Identical 7.5 V, ±5%, DO-35 package but older NXP series with higher max. r_diff (100 Ω)	Higher dynamic impedance reduces regulation accuracy under varying load	Prefer for legacy redesigns where BZX79-C7V5,113 is obsolete

Compared with 1N4733A and BZX55C7V5, BZX79-C7V5,113 offers superior thermal resistance (380 K/W), tighter differential resistance control (30–80 Ω), and guaranteed 1 μA leakage at 5 V - making it optimal for precision analog references in compact industrial modules.

FAQ

What is the maximum continuous power dissipation for BZX79-C7V5,113?

The device is rated for 500 mW total power dissipation at an ambient temperature of 50 °C with leads mounted per standard PCB layout (lead length ≤8 mm). Derating is required above 50 °C at 4.2 mW/°C based on its 380 K/W thermal resistance.

How does the temperature coefficient affect regulation accuracy?

With a typical temperature coefficient of +3.7 mV/K, the Zener voltage increases by approximately 0.05% per °C rise. Over a −40 to +125 °C range, this results in ±0.6 V drift - requiring compensation in high-accuracy references or selection of tighter-tolerance variants.

Can BZX79-C7V5,113 be used in place of a BZX79-B7V5?

Yes, but with trade-offs: the B-series has ±2% tolerance (7.35–7.65 V same as C-series) and lower differential resistance (30–80 Ω vs. 30–80 Ω typical), while the C-series offers lower cost and sufficient accuracy for non-critical biasing and clamping uses.

What is the reverse leakage current specification at 5 V?

The datasheet specifies a maximum reverse leakage current of 1 μA at V_R = 5 V and T_j = 25 °C. This value remains stable across the full operating temperature range and supports low-power reference node integrity in battery-operated systems.
