Product details
Overview
BB153,115 from NXP Semiconductors is a planar-technology variable capacitance diode (varactor) in SOD323 (SC-76) package, designed for VHF electronic tuning and voltage-controlled oscillator (VCO) circuits. It delivers Cd(1V) = 34.65–42.35 pF, Cd(28V) = 2.361–2.754 pF, capacitance ratio of 13.5–15:1 at 1 MHz, series resistance rs = 0.65–0.8 Ω at 100 MHz, and matching accuracy ≤2 % via Direct Matching Assembly (DMA).
For engineers reviewing the BB153,115 datasheet, BB153,115 pinout, BB153,115 application, or BB153,115 equivalent, key selection criteria include reverse voltage range (up to 32 V), low leakage (≤10 nA at VR = 30 V, Tj = 25 °C), tight capacitance matching across diode pairs, and SOD323 footprint compatibility for high-density VHF tuner modules.
Technical Context
The BB153,115 operates as a reverse-biased junction capacitor whose depletion width-and thus capacitance-varies nonlinearly with applied DC bias. Its planar construction enables precise doping control, supporting stable capacitance-voltage (C-V) characteristics from 0 °C to +85 °C.
It employs gliding matching and Direct Matching Assembly (DMA) to achieve ≤2 % capacitance matching across sequences of 10 diodes, critical for balanced VCO core designs and differential tuning networks where phase symmetry and frequency stability are essential.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Cd(1V) | 34.65–42.35 pF: sets minimum VCO tuning range and input impedance at low bias |
| Cd(28V) | 2.361–2.754 pF: defines maximum oscillation frequency and high-bias tuning endpoint |
| Capacitance ratio | 13.5–15:1 at 1 MHz: determines total VCO frequency tuning bandwidth |
| rs (series resistance) | 0.65–0.8 Ω at 100 MHz: limits Q-factor degradation and phase noise in resonant tank circuits |
| VR (max reverse voltage) | 32 V: establishes safe DC bias headroom for VHF tuner applications up to 460 MHz |
| IR (reverse current) | ≤10 nA at VR = 30 V, Tj = 25 °C: ensures minimal bias current draw and thermal drift in precision tuning |
| Matching tolerance | ≤2 % over 10-diode sequence via DMA: enables matched-pair use in differential VCOs without trimming |
Pinout & Package
Package: SOD323 (SC-76), plastic surface-mounted, 2-lead, 1.35 × 0.80 × 0.45 mm body, cathode indicated by marking bar.

Key Features
| Feature | Design Value |
|---|---|
| Capacitance linearity | Optimized C-V curve slope for reduced harmonic distortion in wideband VCO tuning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar varactor diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BBY52,115 | Higher Cd(1V) = 47–57 pF; lower capacitance ratio ~10:1; same SOD323 package | Better suited for lower-frequency (MF/HF) tuning where wider absolute capacitance is prioritized over ratio | Select BBY52,115 when target frequency range is below 200 MHz and higher initial capacitance improves loop stability |
| SMV1232-011 | Higher VR(max) = 30 V (vs. 32 V); Cd(28V) = 2.2 pF; tighter matching spec (±1.5 %) but no DMA documentation | Designed for cellular infrastructure VCOs; optimized for 800–2200 MHz, not VHF-optimized C-V linearity | Choose SMV1232-011 only if operating above 500 MHz and matching tolerance is more critical than VHF C-V smoothness |
Compared with BBY52,115 and SMV1232-011, the BB153,115 uniquely balances VHF-optimized C-V linearity, 15:1 tuning ratio, and factory DMA matching-making it the preferred choice for Band B TV tuners and 100–460 MHz VCOs where phase noise and tracking stability are design-critical.

FAQ
What is the maximum reverse voltage rating for BB153,115?
The BB153,115 has a maximum continuous reverse voltage (VR) rating of 32 V, per IEC 60134 Absolute Maximum Ratings. Peak reverse voltage is rated at 35 V when used in series with a 10 kΩ resistor. Exceeding these values risks permanent junction damage, and operation should remain within the recommended 1 V to 28 V bias range for specified capacitance behavior.
How is capacitance matching achieved in BB153,115?
The BB153,115 achieves ≤2 % capacitance matching across sequences of 10 diodes using a Direct Matching Assembly (DMA) procedure combined with gliding matching during fabrication. This process ensures consistent Cd(1V)/Cd(28V) ratios and C-V curve alignment-critical for differential VCO cores and balanced tuner architectures where pair-to-pair tracking directly impacts frequency stability.
What does the marking code 'PC' indicate on BB153,115?
The marking code 'PC' laser-etched on the BB153,115 device body identifies the specific type number and confirms compliance with NXP's BB153 product family specifications. It is not a date or lot code; rather, it serves as a visual verification that the SOD323-packaged unit is the genuine BB153,115 varactor diode with guaranteed electrical parameters and DMA matching capability.
Can BB153,115 be used in automotive applications?
No-BB153,115 is not automotive-qualified. Per NXP's legal disclaimers, it is neither tested nor warranted for automotive use, including infotainment tuners or telematics VCOs. For such applications, designers must select components explicitly marked "AEC-Q200 qualified" and validated for extended temperature and reliability requirements beyond BB153,115's −55 °C to +125 °C junction range.
What is the typical series resistance of BB153,115 and why does it matter?
The BB153,115 exhibits a typical series resistance (rs) of 0.65 Ω at 100 MHz and Cd = 30 pF. This low value directly limits resistive losses in high-frequency resonant tanks, preserving Q-factor and minimizing phase noise in VCOs. In practice, rs < 0.8 Ω ensures stable oscillation and reduced jitter when the BB153,115 is integrated into 100–460 MHz LC oscillator designs.
