Product details

Overview

BZX84-C36/DG/B2,23 from Nexperia is a surface-mount 36 V Zener diode in SOT23 package with 500 mW power dissipation, ±5% tolerance, and 100 nA maximum reverse leakage at 27.4 V. It provides precise voltage regulation in low-power biasing and reference circuits for industrial sensor interfaces.

For engineers reviewing the BZX84-C36/DG/B2,23 datasheet, BZX84-C36/DG/B2,23 pinout, BZX84-C36/DG/B2,23 application, or BZX84-C36/DG/B2,23 equivalent, key selection criteria include Zener voltage accuracy, thermal stability under 100 °C ambient, SOT23 footprint compatibility, and reverse leakage performance at derated voltage.

Technical Context

This Zener diode operates in reverse breakdown mode to maintain stable voltage across its terminals. Its 36 V nominal Zener voltage is specified at test current of 5 mA, with dynamic impedance of 130 Ω typical at that condition and 200 Ω maximum at 1 mA.

The device exhibits a positive temperature coefficient of +0.075 %/K above 5.1 V, resulting in predictable voltage drift over -65 °C to +150 °C operating range. Junction-to-ambient thermal resistance is 430 K/W in standard PCB layout per JEDEC MS-012.

Key Specifications

Parameter	Value and Actual Design Meaning
Zener Voltage (V_Z)	36 V ±5% at I_Z = 5 mA - defines regulated output voltage in shunt regulator designs
Power Dissipation (P_tot)	500 mW - limits continuous current to ~13.9 mA at 36 V without heatsinking
Reverse Leakage (I_R)	≤100 nA at V_R = 27.4 V - ensures minimal error current in high-impedance reference nodes
Zener Impedance (Z_ZT)	130 Ω typical at 5 mA - determines regulation sensitivity to load current changes
Operating Temperature	-65 °C to +150 °C - supports automotive under-hood and industrial control environments
Package	SOT23 - enables automated placement and fits 1.3 mm × 0.8 mm PCB area

FAQ

What is the maximum reverse voltage before breakdown for BZX84-C36/DG/B2,23?

The device begins controlled breakdown at 34.2 V (36 V × 0.95) and reaches full regulation by 37.8 V (36 V × 1.05). Below 27.4 V, reverse leakage remains ≤100 nA - no significant conduction occurs until near the specified Zener voltage window.

Can BZX84-C36/DG/B2,23 be used in series for higher voltage reference?

Yes, but with caution: series connection increases total dynamic impedance and temperature coefficient. Two units yield ~72 V nominal, but combined Z_ZT rises to ~260 Ω and tempco becomes additive, requiring recalibration for precision applications.

Is this Zener diode suitable for surge protection?

No - it is not rated for transient energy absorption. With only 500 mW steady-state power, it cannot handle ESD or lightning-induced surges. Use dedicated TVS diodes like PESD5V0S1BA for such protection functions.

How does soldering affect the Zener voltage specification?

Reflow profiles compliant with JEDEC J-STD-020 do not shift V_Z; however, excessive localized heating (>260 °C for >30 s) may alter junction characteristics. Standard SMT reflow causes no measurable drift when using recommended thermal profiles.
