Product details

Overview

BZX79-C13,113 from Nexperia is a ±5% tolerance Zener voltage regulator diode with nominal breakdown voltage of 13 V at 8 V reverse bias and 100 nA maximum reverse leakage current. It delivers stable low-power voltage reference in compact hermetically sealed SOD27 (DO-35) glass package, rated for 500 mW total power dissipation at 50 °C ambient, and used in precision analog supply rails and sensor biasing circuits.

For engineers reviewing the BZX79-C13,113 datasheet, BZX79-C13,113 pinout, BZX79-C13,113 application, or BZX79-C13,113 equivalent, key selection criteria include Zener voltage tolerance (±5%), differential resistance (≤170 Ω), temperature coefficient (+7.0 to +11.0 mV/K), non-repetitive peak reverse power (40 W), and junction-to-ambient thermal resistance (380 K/W).

Technical Context

This Zener diode operates in reverse breakdown mode with tightly controlled V_Z = 12.7–14.1 V at I_Ztest = 8 mA, exhibiting a positive temperature coefficient of +7.0 to +11.0 mV/K - enabling predictable drift compensation in reference designs. Its differential resistance of ≤170 Ω at 5 mA ensures minimal output impedance under load variation.

The device uses axial-leaded hermetic glass construction (SOD27/DO-35), with cathode identified by a black band. It supports non-repetitive surge handling up to 40 W for 100 μs pulses and maintains stable operation across −65 °C to +200 °C storage and junction temperature ranges.

Key Specifications

Parameter	Value and Actual Design Meaning
Zener Voltage (V_Z)	12.7–14.1 V at I_Z = 8 mA - defines precise regulation point for low-current reference applications
Reverse Leakage (I_R)	≤100 nA at V_R = 8 V - ensures minimal quiescent current draw in battery-powered circuits
Differential Resistance (r_diff)	≤170 Ω at I_Z = 5 mA - limits output voltage deviation under varying load currents
Power Dissipation (P_tot)	500 mW at T_amb = 50 °C - sets maximum continuous DC power handling on standard PCB layout
Temperature Coefficient (S_Z)	+7.0 to +11.0 mV/K - enables predictable thermal drift modeling for compensated references
Junction-to-Ambient R_th	380 K/W - determines steady-state temperature rise above ambient at full power
Package	SOD27 (DO-35) - axial glass package with cathode band, compatible with through-hole wave soldering

Pinout & Package

Hermetically sealed axial-leaded SOD27 (DO-35) glass package with cathode identified by a single black band. Leads are tinned copper-clad steel; body diameter 1.85 mm, length 4.25 mm, lead spacing 25.4 mm.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Forward conduction terminal / low-side connection in reverse-biased configuration	Connected to lower potential node when used as shunt regulator; carries forward current up to 250 mA
Cathode	Zener breakdown terminal / high-side connection in reverse-biased configuration	Marked with black band; connected to regulated voltage node; sustains reverse breakdown at 13 V nominal

Key Features

Feature	Design Value
±5% Zener voltage tolerance	Enables cost-effective voltage referencing where tight regulation is not required, e.g., power supply feedback or overvoltage detection
Hermetic glass SOD27 package	Provides long-term stability and moisture resistance without conformal coating, critical for industrial and automotive environments
Non-repetitive 40 W surge rating	Withstands transient overvoltage events (e.g., ESD or inductive kickback) without degradation when properly current-limited
Low 100 nA reverse leakage at 8 V	Minimizes standby power loss in always-on sensor bias or microcontroller reset circuits
Positive temperature coefficient	Allows predictable thermal drift tracking - useful when paired with negative-coefficient components for compensation

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
1N4742A	Same 12 V nominal, but ±5% tolerance and 1.0 W power rating in DO-41 package	Higher power handling suits higher-current regulation; larger DO-41 footprint requires PCB redesign	Select when >500 mW continuous dissipation is needed; avoid if space-constrained or legacy DO-35 compatibility required
BZX55C13	13 V ±5%, 500 mW, but in larger DO-35 variant with higher r_diff (≤250 Ω) and looser tempco control	Less stable regulation under load variation and wider thermal drift; suitable only for non-critical references	Choose only for cost-sensitive, non-precision applications where 170 Ω vs. 250 Ω r_diff and uncontrolled tempco are acceptable

Compared with 1N4742A and BZX55C13, BZX79-C13,113 offers tighter differential resistance (≤170 Ω), better-defined temperature coefficient (+7–11 mV/K), and guaranteed hermetic sealing - making it preferable for industrial analog references where long-term stability and thermal predictability are essential.

FAQ

What is the maximum continuous reverse voltage this diode can regulate at?

The BZX79-C13,113 is specified for nominal Zener voltage of 12.7–14.1 V at 8 mA test current. Its absolute maximum reverse voltage is not defined separately - operation must remain within the 500 mW power limit and −65 °C to +200 °C junction temperature range. Exceeding 14.1 V continuously risks thermal runaway if current is not externally limited.

Can this diode be used in surface-mount designs?

No - BZX79-C13,113 uses an axial-leaded SOD27 (DO-35) glass package intended exclusively for through-hole mounting. It lacks solder pads or terminations compatible with reflow or wave soldering of SMT boards. For SMT equivalents, consider Nexperia's PZM series or similar SOD-123 Zeners.

How does its temperature coefficient affect regulation accuracy over temperature?

With a specified temperature coefficient of +7.0 to +11.0 mV/K, the Zener voltage increases linearly with junction temperature. Over a 100 °C range (e.g., −25 °C to +75 °C), V_Z shifts by +0.7–1.1 V - a ~5–8% change relative to 13 V. This must be factored into reference design margins or compensated using complementary components.

Is the cathode polarity marked on the device body?

Yes - the cathode is clearly identified by a single black band on the glass body, consistent with industry-standard DO-35 marking convention. This band must be oriented toward the higher-potential node when used in reverse-biased Zener regulation configuration.
