Product details

Overview

BZV85-C11,113 from Nexperia is a medium-power Zener voltage regulator diode in a hermetically sealed SOD66 (DO-41) glass package, rated for 11 V nominal working voltage with ±5 % tolerance, 1.3 W total power dissipation at T_tp = 55 °C, and 60 W non-repetitive peak reverse power handling - used for precision DC voltage stabilization in low-to-medium power linear power supplies and reference circuits.

For engineers reviewing the BZV85-C11,113 datasheet, BZV85-C11,113 pinout, BZV85-C11,113 application, or BZV85-C11,113 equivalent, key selection criteria include Zener voltage accuracy (10.4–11.6 V), differential resistance (≤10 Ω at I_test = 2 mA), temperature coefficient (+5.3 to +9.3 mV/K), junction-to-tie-point thermal resistance (110 K/W), and axial-leaded SOD66 mechanical compatibility.

Technical Context

This Zener diode operates in reverse breakdown mode with tightly controlled V_Z and low dynamic impedance (r_dif ≤ 10 Ω), enabling stable regulation under varying load and temperature conditions. Its positive temperature coefficient (+5.3 to +9.3 mV/K) supports predictable drift behavior in bias networks.

The device uses a hermetically sealed glass package with axial leads, ensuring long-term stability and moisture resistance. Thermal performance is defined with two test conditions: 1.3 W P_tot when leads are held at 55 °C at 4 mm from body, and 1 W when ambient is 25 °C with 10 mm lead length.

Key Specifications

Parameter	Value and Actual Design Meaning
Nominal Zener Voltage	11 V (min 10.4 V, max 11.6 V at I_test = 2 mA - defines regulated output level in shunt configuration)
Differential Resistance	≤10 Ω (at I_test = 2 mA - determines regulation stiffness against load current changes)
Temperature Coefficient	+5.3 to +9.3 mV/K (at I_test = 2 mA - quantifies V_Z drift per degree Celsius)
Total Power Dissipation	1.3 W (with leads held at 55 °C at 4 mm from body - sets maximum continuous DC power handling)
Non-repetitive Peak Reverse Power	60 W (100 µs square wave - supports transient overvoltage clamping without failure)
Forward Voltage	≤1 V (at I_F = 50 mA - ensures low loss in forward-biased protection or logic interface roles)
Junction Temperature Limit	200 °C (absolute maximum - constrains thermal design margin in PCB layout)

Pinout & Package

Hermetically sealed SOD66 (DO-41) axial glass package with 2 leads: cathode marked by a band; anode unmarked. Package dimensions: D = 2.6 mm (max), L = 25.4 mm (max), b = 0.81 mm (min lead diameter).

Pin/Terminal	Circuit Role	Design Meaning
1 (banded end)	Cathode	Connected to regulated output node in shunt configuration; reverse-biased during regulation
2 (unbanded end)	Anode	Connected to circuit ground or common reference; completes reverse-bias path

Key Features

Feature	Design Value
Hermetic glass sealing	Prevents moisture ingress and long-term parameter drift in humid or industrial environments
E24 voltage series coverage	33 discrete values from 3.6 V to 75 V - enables precise matching to common supply rails and reference levels
Low differential resistance	≤10 Ω at 2 mA - minimizes output voltage variation across load current changes in shunt regulators
Controlled temperature coefficient	+5.3 to +9.3 mV/K - allows predictable compensation in temperature-sensitive analog circuits
High surge capability	60 W non-repetitive peak power (100 µs) - provides robust transient suppression in power rail protection

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
1N4740A	10 V nominal, ±5 % tolerance, 1 W P_tot, DO-41 package, r_dif ≈ 20 Ω	Lower regulation voltage and higher dynamic impedance - less suitable for tight-tolerance 11 V references	Select only if 10 V output and relaxed regulation stiffness are acceptable
BZX85C11	11 V nominal, ±5 %, 1.3 W P_tot, DO-41, r_dif ≤ 15 Ω, but plastic package (less hermetic)	Higher moisture sensitivity and longer-term V_Z drift risk in humid environments	Prefer for cost-sensitive consumer designs where long-term stability is secondary

Compared with 1N4740A and BZX85C11, BZV85-C11,113 delivers tighter voltage matching to 11 V systems, lower dynamic impedance for improved load regulation, and hermetic sealing for superior long-term reliability in industrial and automotive deployments.

FAQ

What is the exact Zener voltage range for BZV85-C11,113 at 2 mA test current?

The BZV85-C11,113 exhibits a guaranteed Zener voltage range of 10.4 V to 11.6 V when measured at I_test = 2 mA and T_j = 25 °C, per Table 8 of the Nexperia datasheet Rev. 03. This ±5.5 % spread aligns with E24 series tolerancing and is validated under specified thermal conditions.

Can BZV85-C11,113 be used in surface-mount designs?

No - BZV85-C11,113 uses an axial-leaded SOD66 (DO-41) glass package intended for through-hole mounting only. It lacks solder pads or gull-wing/leadless terminations required for SMT assembly. For SMD equivalents, consider Nexperia's BZX384-B11 or BZX84-C11 in SOT23.

What is the maximum allowable forward current for continuous operation?

The absolute maximum forward current is 500 mA, as specified in Table 5 (Limiting Values). However, sustained forward conduction is not typical in Zener regulation use; the device is optimized for reverse-bias operation, and forward voltage is capped at ≤1 V at 50 mA per Table 7.

How does thermal resistance affect power derating in PCB layouts?

R_th(j-t) = 110 K/W (junction-to-tie-point, 4 mm lead length) means each watt dissipated raises junction temperature by 110 K above tie-point temperature. With tie-points held at 55 °C, the 1.3 W rating assumes junction stays ≤198 °C - below the 200 °C limit. Reducing copper area or increasing ambient temperature requires proportional power reduction.
