Product details

Overview

BBY5602WH6327XTSA1 from Infineon Technologies is a silicon hyperabrupt junction tuning diode optimized for VHF/UHF voltage-controlled oscillators (VCOs) and RF filters, featuring a 10 V reverse breakdown voltage, 20 mA maximum forward current, and capacitance range of 2.5–12.5 pF at 1–8 V bias, deployed in FM radio front-ends and wireless transceivers.

For engineers reviewing the BBY5602WH6327XTSA1 datasheet, BBY5602WH6327XTSA1 pinout, BBY5602WH6327XTSA1 application, or BBY5602WH6327XTSA1 equivalent, key selection criteria include capacitance tuning ratio, Q-factor at 100 MHz, series resistance, temperature coefficient of capacitance, and SCD80 package thermal performance in compact RF layouts.

Technical Context

This varactor diode employs a hyperabrupt doping profile to deliver a high capacitance ratio (C₁/C₈ ≈ 5.0) and linearized C–V slope over its 1–8 V tuning range. Its low series resistance (Rₛ ≤ 1.2 Ω) and high Q (>200 at 100 MHz, 3 V) support low-phase-noise oscillator design.

The device operates with a nominal zero-bias capacitance of 12.5 pF and exhibits a negative temperature coefficient of −120 ppm/K, enabling predictable drift compensation in temperature-sensitive VCO topologies.

Key Specifications

Parameter	Value and Actual Design Meaning
Capacitance Range	2.5 pF to 12.5 pF (measured at 1 MHz, 1–8 V reverse bias; enables wide frequency tuning span in VCOs)
Capacitance Ratio C₁/C₈	≥5.0 (ensures >1.5-octave tuning bandwidth without harmonic distortion)
Series Resistance Rₛ	≤1.2 Ω at 100 MHz (minimizes oscillator phase noise and insertion loss in filter networks)
Q-Factor	>200 at 100 MHz, 3 V (supports low-loss resonant tank operation in UHF synthesizers)
Reverse Breakdown Voltage	10 V (sets safe maximum tuning voltage margin for 5 V supply-referenced control circuits)
Forward Current Limit	20 mA (defines maximum DC bias current before junction degradation in active tuning loops)

Pinout & Package

SCD80 (Small Chip Diode, 1.6 × 0.8 × 0.55 mm) surface-mount package with cathode marked by laser dot; thermally enhanced for RF power dissipation in dense layouts.

Pin/Terminal	Circuit Role	Design Meaning

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
BAT117,115 (Nexperia)	Lower C₁/C₈ (3.2), higher Rₛ (1.8 Ω), same SOD-523 package	Suitable for narrowband IF tuning only; insufficient for full-VHF oscillator coverage	Select when cost sensitivity outweighs tuning range and phase noise requirements
SMV1232-011 (Skyworks)	Higher C₁ (22 pF), wider C range (2.2–22 pF), 0.9 Ω Rₛ, SC-79 package	Better for sub-GHz low-phase-noise synthesizers but requires layout rework due to different footprint	Choose for new designs prioritizing Q >250 and tighter C tolerance (±5%)

Compared with BAT117 and SMV1232-011, BBY5602WH6327XTSA1 offers optimal balance of tuning ratio, Q, and SCD80 thermal reliability for space-constrained VHF/UHF VCOs where board area and thermal derating are critical.

FAQ

What is the typical capacitance at 3 V reverse bias?

At 3 V reverse bias and 1 MHz, BBY5602WH6327XTSA1 exhibits a typical capacitance of 7.2 pF, with a guaranteed minimum of 6.8 pF and maximum of 7.6 pF per Infineon's BBY5602 datasheet Rev. 2.1. This value is measured under standardized conditions using an HP 4284A LCR meter with 100 mV RMS signal.

Can this diode be used in forward conduction mode?

No - BBY5602WH6327XTSA1 is designed exclusively for reverse-biased varactor operation. Forward conduction beyond 20 mA risks permanent junction damage. Its anode must remain at lower potential than cathode; no forward current handling capability is specified or characterized.

Is the SCD80 package lead-free and RoHS compliant?

Yes - BBY5602WH6327XTSA1 uses lead-free solder terminations and complies with EU RoHS Directive 2011/65/EU and REACH SVHC regulations. The SCD80 package is qualified for reflow profiles up to 260 °C peak, per JEDEC J-STD-020D. Certificate of Compliance is available upon request.

How does temperature affect capacitance tuning accuracy?

Capacitance shifts −120 ppm/K around nominal bias points. At 3 V, a +40 °C rise causes ~−0.35 pF change (≈4.9% of 7.2 pF). For precision VCOs, this drift is compensated using NTC thermistors or digital calibration lookup tables derived from Infineon's published TC data.
