Product details

Overview

BBY5202LE6816XTMA1 from Infineon Technologies is a silicon hyperabrupt tuning diode optimized for low-voltage VCO tuning in mobile communication transceivers, featuring 1.4–2.2 pF capacitance at 1 V–4 V reverse bias, 0.9–1.7 Ω series resistance at 1 GHz, and AEC-Q101 qualification for automotive-grade reliability.

For engineers reviewing the BBY5202LE6816XTMA1 datasheet, BBY5202LE6816XTMA1 pinout, BBY5202LE6816XTMA1 application, or BBY5202LE6816XTMA1 equivalent, key selection criteria include capacitance vs. voltage linearity (CT1/CT4 = 1.1–2.1), low IR (<10 nA @ 6 V, 25°C), RoHS-compliant TSLP-2-1 leadless package, and high Q-factor suitability for 800 MHz–2.5 GHz VCO designs.

Technical Context

This hyperabrupt junction varactor diode delivers voltage-dependent capacitance with steep C–V slope (dC/dV ≈ −0.3 pF/V near 1 V), enabling fine frequency resolution in compact VCOs. Its low rS (typ. 0.9 Ω) minimizes phase noise contribution in oscillator tank circuits.

The device operates across −55°C to +150°C, with IR ≤200 nA at 6 V and 85°C, supporting stable tuning in thermally demanding RF front-end modules. The SCD80/TSLP-2-1 package ensures minimal parasitic inductance (LS = 0.4 nH) and consistent solder-joint reliability.

Key Specifications

Parameter	Value and Actual Design Meaning
Capacitance @ 1 V	1.4–2.2 pF - sets VCO center frequency and tuning range lower bound
Capacitance @ 4 V	0.85–1.45 pF - defines upper frequency limit and tuning ratio
Capacitance Ratio CT1/CT4	1.1–2.1 - determines usable VCO frequency span per volt of tuning voltage
Series Resistance rS	0.9–1.7 Ω @ 1 GHz - directly impacts VCO phase noise and Q-factor degradation
Reverse Current IR	<10 nA @ 6 V, 25°C - ensures low leakage-induced tuning drift and power loss
Max Reverse Voltage VR	7 V - defines absolute tuning voltage ceiling without breakdown risk
Operating Temp Range	−55°C to +150°C - supports under-hood automotive and industrial RF module deployment

Pinout & Package

Package: TSLP-2-1 (SCD80), leadless surface-mount, 1.3 mm × 0.7 mm × 0.35 mm, cathode-marked via laser on top surface.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
BAR63-02W	Abupt (not hyperabrupt) junction; CT1/CT4 = 1.0–1.4; rS = 1.2–2.5 Ω	Narrower tuning range; higher phase noise in wideband VCOs	Prefer for cost-sensitive, non-automotive 2G/3G designs where linearity is less critical
BBY58-02W	Higher C range (2.5–4.5 pF @ 1 V); CT1/CT4 = 1.3–2.5; rS = 1.1–2.0 Ω	Better low-frequency coverage (700–900 MHz); larger die size increases parasitics above 2 GHz	Select when targeting sub-1 GHz VCOs with wider capacitance span and relaxed high-frequency Q requirements

Compared with BAR63-02W and BBY58-02W, BBY5202LE6816XTMA1 offers superior C–V linearity and lower rS for high-frequency, low-phase-noise VCOs-especially where AEC-Q101 compliance and thermal stability across −55°C to +150°C are mandatory.

FAQ

What is the maximum recommended reverse voltage for continuous operation?

The absolute maximum reverse voltage is 7 V, but for reliable long-term operation in VCO applications, Infineon specifies 6 V as the maximum rated reverse bias. Exceeding this risks irreversible junction degradation and increased IR drift, especially above 85°C ambient.

Does BBY5202LE6816XTMA1 require external biasing circuitry for VCO integration?

No external active biasing is required. The diode operates with a simple DC blocking capacitor and RF choke configuration. A 100 kΩ pull-up resistor to 3.3 V or 5 V rail provides stable tuning voltage while isolating RF from the bias source.

How does the TSLP-2-1 package affect high-frequency performance compared to traditional SOD-323?

TSLP-2-1 reduces lead inductance to 0.4 nH (vs. ~1.2 nH in SOD-323), lowering self-resonant frequency shift and preserving C–V linearity up to 2.5 GHz. Its symmetric pad layout also improves impedance matching in 50 Ω microstrip layouts.

Is BBY5202LE6816XTMA1 suitable for use in medical telemetry devices?

While AEC-Q101 qualified and RoHS-compliant, BBY5202LE6816XTMA1 is not certified for life-support applications. Infineon explicitly restricts use in implanted or critical-care devices unless granted written approval-consult Infineon's safety disclaimer for full regulatory constraints.
