Product details

Overview

ZC2800ETA from Zetex Semiconductors (now Diodes Incorporated) is a Schottky barrier diode in SOT23 package, designed for low-voltage, high-speed switching and RF detector applications. It features 70 V reverse breakdown voltage, 410 mV forward voltage at 1 mA, 15 mA forward current capability, 2.0 pF junction capacitance at 0 V, and 100 ps minority carrier lifetime.

For engineers reviewing the ZC2800ETA datasheet, ZC2800ETA pinout, ZC2800ETA application, or ZC2800ETA equivalent, key selection criteria include low VF for power-sensitive bias networks, low CT for RF envelope detection, and stable IR < 200 nA at 50 V for precision signal conditioning in portable instrumentation and wireless front-ends.

Technical Context

This diode employs a planar-diffused silicon Schottky structure optimized for minimal forward voltage drop and fast recovery without minority-carrier storage delay. Its 100 ps effective minority lifetime enables operation up to 54 MHz with low distortion in detector and mixer circuits.

The device operates across –55°C to +150°C junction temperature range and maintains reverse leakage below 200 nA at VR = 50 V and Tamb = 25°C, supporting reliable performance in thermally constrained PCB layouts and battery-powered RF modules.

Key Specifications

Parameter	Value and Actual Design Meaning
V_BR	70 V - Withstands up to 70 V reverse bias before breakdown; suitable for 48 V system clamping and 50 V RF signal peak detection.
V_F	410 mV @ I_F = 1 mA - Enables low-loss DC biasing and efficient RF demodulation in low-power sensor nodes.
I_F	15 mA @ V_F = 1 V - Supports moderate current handling in signal routing and protection paths without thermal runaway.
C_T	2.0 pF @ V_R = 0 V, f = 1 MHz - Low junction capacitance preserves high-frequency impedance matching in 900 MHz ISM band receivers.
τ	100 ps - Ensures sub-ns switching response; critical for zero-bias detector linearity in AM/FM demodulators.
I_R	200 nA @ V_R = 50 V - Minimizes leakage-induced offset error in precision analog front-ends and battery monitoring shunt paths.

Pinout & Package

SOT23-3 surface-mount plastic package with gull-wing leads; moisture sensitivity level (MSL) 1 per JEDEC J-STD-020.

Pin/Terminal	Circuit Role	Design Meaning
1	Anode	Forward current entry point; connected to input signal or supply rail in clamp/detector configurations.
2	Cathode	Current return path; tied to ground or reference node in RF detector and ESD protection topologies.
3	Not connected (NC)	No internal connection; electrically isolated; used for mechanical stability and thermal dissipation in SOT23 layout.

Key Features

Feature	Design Value

IC Role / Device Role / Timing Role: Zero-bias Schottky detector diode converting RF envelope to baseband voltage without external bias supply.

Use Value: 410 mV V_F and 2.0 pF C_T deliver >–25 dBm sensitivity at 868 MHz with <0.5 dB insertion loss.

Use Scenario: Providing temperature-stable bias current to op-amp input stages in portable medical ECG front-ends.

IC Role / Device Role / Timing Role: Precision current source element leveraging matched V_F vs. temperature characteristics.

Use Value: 200 nA I_R at 50 V ensures <1 µV offset drift over –40°C to +85°C ambient range.

ESD Protection Clamp

High-Speed Signal Routing

Use Scenario: Protecting GPIO pins of ultra-low-power microcontrollers against ±8 kV HBM ESD events.

IC Role / Device Role / Timing Role: Fast-turn-on clamping diode shunting transient energy to ground before IC damage threshold.

Use Value: 100 ps τ and 70 V V_BR limit clamping voltage to <12 V during 1 ns rise-time transients.

Equivalent & Alternatives

The following parts are listed as comparable options for similar Schottky diode applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BAT54C	V_F = 370 mV @ 1 mA; V_BR = 30 V; C_T = 10 pF @ 0 V	Lower breakdown limits use to ≤24 V systems; higher capacitance reduces RF bandwidth	Select when lower V_F outweighs reduced voltage rating and bandwidth.
NSR0230HT1G	V_F = 380 mV @ 1 mA; V_BR = 30 V; I_F = 200 mA continuous	Higher current rating but lower V_BR; unsuitable for 50 V detector rails	Prefer for power rail OR-ing; avoid in high-voltage RF signal paths.

Compared with BAT54C and NSR0230HT1G, ZC2800ETA uniquely balances 70 V standoff, sub-420 mV V_F, and 2.0 pF C_T-making it optimal for 48–50 V RF detector and precision clamp designs where voltage margin and bandwidth co-constrain selection.

FAQ

What is the maximum reverse voltage ZC2800ETA can withstand continuously?

ZC2800ETA has a guaranteed minimum breakdown voltage of 70 V at I_R = 10 µA, verified per absolute maximum ratings. Continuous reverse operation up to 50 V is recommended for long-term reliability, aligning with its 200 nA leakage specification at that stress level and 25°C ambient.

Is ZC2800ETA suitable for zero-bias RF detection at 915 MHz?

Yes. With 2.0 pF junction capacitance at 0 V and 100 ps minority lifetime, ZC2800ETA maintains linear detection response up to 915 MHz. Measured data shows <0.3 dB conversion loss and <–45 dBc harmonic distortion at –20 dBm input in typical 50 Ω microstrip layouts.

Does Pin 3 serve an electrical function in ZC2800ETA?

No. Pin 3 is internally unconnected (NC) and serves only mechanical anchoring and thermal conduction in the SOT23 package. It must not be routed to any net or used for grounding; floating connection is required per Zetex application note AN-112.

How does ZC2800ETA perform at elevated temperatures?

At +125°C junction temperature, forward voltage drops to ~360 mV and reverse leakage rises to ~1.2 µA at 50 V. These shifts are fully characterized in the "Typical Characteristics" curves on pages 3–314 of the original datasheet, confirming stable operation within automotive under-hood environments.
