Product details

Overview

BB200,215 from NXP Semiconductors (formerly Philips) is a low-voltage silicon planar variable capacitance double diode with common cathode configuration in SOT23 package, featuring C_1V = 70 pF, C_4.5V = 13.4 pF, capacitance ratio ≥5, series resistance ≤0.6 Ω at 100 MHz, and rated for 18 V reverse voltage - used in FM radio tuning and voltage-controlled oscillators.

For engineers reviewing the BB200,215 datasheet, BB200,215 pinout, BB200,215 application, or BB200,215 equivalent, this page delivers verified electrical parameters, SOT23 terminal mapping, real-world VCO/FM tuning use cases, and two validated alternative varicaps with documented capacitance and packaging differences.

Technical Context

The BB200,215 integrates two identical hyperabrupt junction varicap diodes sharing a single cathode terminal, enabling dual-tuned circuit operation without inter-device mismatch. Its steep C/V curve (C_1V/C_5V ≥5) supports wide frequency sweep range in compact VCO designs.

Designed for low-voltage biasing (up to 18 V reverse), it maintains low series resistance (0.43–0.6 Ω at 100 MHz, VR = 1.5 V) and exhibits temperature-stable capacitance variation (TCd ≈ −100 ppm/K at VR = 1 V), critical for stable oscillator center frequency.

Key Specifications

Parameter	Value and Actual Design Meaning
C_1V	70 pF ±4.2 pF at 1 MHz - sets minimum VCO tank capacitance and defines upper frequency limit
C_4.5V	13.4 pF typical at 1 MHz - determines mid-band tuning point and linearity in FM IF stages
Capacitance Ratio	≥5 (C_1V/C_5V) - enables >2:1 frequency tuning range in LC resonators without external switching
Series Resistance r_s	0.43–0.6 Ω at 100 MHz, VR = 1.5 V - limits Q-factor degradation and phase noise in oscillator tanks
Max Reverse Voltage	18 V - supports standard 5–12 V tuning supply rails with 50% safety margin
Reverse Leakage I_R	≤50 nA at VR = 10 V - ensures minimal tuning voltage drift in battery-powered portable radios
Junction Temp Range	−55 °C to +85 °C - qualifies for automotive cabin and industrial ambient environments

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
BBY52,215	C_1V = 25 pF, C_4.5V = 5.5 pF; lower capacitance, higher ratio (≥4.5), same SOT23 package	Better suited for UHF VCOs (>500 MHz); insufficient C_1V for FM band direct tuning	Select BBY52,215 when designing >400 MHz oscillators requiring tighter capacitance tolerance and higher tuning linearity.
SMV1232-011	C_1V = 56 pF, C_4.5V = 12.5 pF; higher r_s (0.9 Ω), SC-70 package (smaller footprint)	Compatible with automated placement on fine-pitch boards but requires layout revision due to different pad geometry	Choose SMV1232-011 only if board space is constrained below 2.0 × 1.25 mm and 0.65 mm pitch reflow is not required.

Compared with BB200,215, BBY52,215 offers higher tuning ratio at lower capacitance for UHF, while SMV1232-011 trades series resistance and package compatibility for miniaturization - neither is pin-compatible, and both require circuit recalibration for FM-band use.

FAQ

What is the maximum reverse voltage rating for BB200,215?

The BB200,215 has a maximum continuous reverse voltage rating of 18 V per diode, as specified in the Absolute Maximum Ratings table. This value is defined under IEC 60134 and must not be exceeded to prevent junction breakdown or permanent device damage. Operation at 12 V or less is recommended for long-term reliability in commercial FM tuner applications. The BB200,215 datasheet confirms this limit applies independently to each anode-to-cathode path.

Does BB200,215 support dual independent tuning paths?

Yes, the BB200,215 supports dual independent tuning paths via its two anodes (Pin 1 and Pin 2) sharing a common cathode (Pin 3). This configuration allows simultaneous but separate voltage control of two LC resonant circuits - essential for stereo FM demodulation or dual-band radio architectures. Each diode operates independently with matched C/V characteristics, as verified in the BB200,215 characterization data at Tj = 25 °C.

What is the typical series resistance of BB200,215 at 100 MHz?

The typical series resistance (r_s) of BB200,215 is 0.43 Ω, measured at 100 MHz and VR = 1.5 V, with a maximum of 0.6 Ω. This low r_s directly impacts oscillator phase noise performance by preserving tank circuit Q-factor. The BB200,215 specification sheet lists this parameter in the "Characteristics" table under conditions matching standard VCO operating points.

Is BB200,215 RoHS compliant?

BB200,215 was originally released in 2001 prior to RoHS Directive 2002/95/EC. While NXP later qualified many legacy SOT23 devices for RoHS compliance via material change notifications, no official RoHS statement exists for BB200,215 in its original manufacturing release. For new designs, Aetrix recommends verifying current lot status with NXP or selecting RoHS-compliant alternatives such as BBY52,215. BB200,215 remains available for legacy repair and continuity programs.

How does temperature affect BB200,215 capacitance?

BB200,215 exhibits a negative temperature coefficient of capacitance (TCd), typically −100 ppm/K at VR = 1 V, as shown in Figure 4 of the BB200,215 datasheet. This means capacitance decreases ~0.01% per °C rise in junction temperature. In VCO applications, this contributes to frequency drift unless compensated - a known behavior confirmed across the BB200,215 family and consistent with hyperabrupt silicon varicaps.
