Product details
Overview
2SC4965YV-TL-E from Renesas Electronics is a silicon NPN epitaxial RF transistor optimized for VHF/UHF RF switch applications, featuring 8 V VCEO, 100 mA IC, 1.2 Ω typical on-resistance (Ron), 1.9 pF Cob, and 150°C maximum junction temperature. It operates in compact CMPAK (SC-70) package for high-density RF front-end switching.
For engineers reviewing the 2SC4965YV-TL-E datasheet, 2SC4965YV-TL-E pinout, 2SC4965YV-TL-E application, or 2SC4965YV-TL-E equivalent, key selection criteria include low Ron at 1 kHz, VHF/UHF signal reduction performance, SC-70 thermal derating curve, and compatibility with 2.7 kΩ base drive in RF switch bias networks.
Technical Context
This device functions as a single-pole, single-throw (SPST) active RF switch using forward-biased NPN operation. Its low Cob (1.9 pF typ.) and high hFE (100–600) enable effective isolation and insertion loss control up to 1 GHz, with signal reduction exceeding –40 dB at 500 MHz under VB = 5 V / 0 V switching.
The 2SC4965YV-TL-E employs epitaxial base construction for stable fT response (up to ~2.4 GHz at IC = 20 mA) and supports DC-coupled or AC-coupled RF path control via base current modulation (IB = 2.5 mA typical for Ron test). Thermal design must respect its 100 mW PC limit and 120 mW max at Ta = 25°C per derating curve.
Key Specifications

|---|---|
| VCEO | 8 V - Maximum allowable collector-emitter voltage during RF switch OFF state without breakdown |
| Ron | 1.2 Ω typ. - Low conduction resistance enabling minimal insertion loss in RF signal paths |
| Cob | 1.9 pF typ. - Low output capacitance ensuring high isolation (>–40 dB) above 200 MHz |
| hFE | 100–600 - Wide DC current gain range supporting robust base drive margin across production lots |
| PC | 100 mW - Absolute maximum power dissipation; derates linearly to zero at 150°C junction temperature |

| 2 (Base) | Control input for transistor turn-on/turn-off | Driven by 2.5 mA typical base current; requires 2.7 kΩ pull-up resistor for VB = 5 V logic-compatible switching |
| 3 (Collector) | RF signal output terminal in series-switch topology | Carries RF signal path; must be impedance-matched to 50 Ω system; voltage swing limited to ≤8 V |
Key Features
| Feature | Design Value |
|---|---|
| Low Ron at 1 kHz | 1.2 Ω typ. enables <0.15 dB insertion loss in 50 Ω systems below 500 MHz |
| High-frequency isolation | –40 dB signal reduction at 500 MHz ensures clean channel separation in multi-band RF modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar RF switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 2SC5004YV-TL-E | Higher VCEO (12 V), lower Ron (0.9 Ω typ.), same SC-70 package | Supports higher-voltage RF stages (e.g., +12 V PA bias rails); better suited for 1 W-class transmitters | Select when VCE stress exceeds 8 V or Ron <1.0 Ω is required for sub-0.1 dB loss targets |
| 2SC4617T106Q | Different package (SOT-323), higher Cob (2.5 pF), same hFE range | Larger footprint (2.2 × 2.2 mm) limits board density; higher Cob reduces isolation above 400 MHz | Choose only if SOT-323 is mandated by legacy layout or procurement constraints |
Compared with 2SC4965YV-TL-E, the 2SC5004YV-TL-E offers superior voltage headroom and conduction efficiency for demanding RF power stages, while the 2SC4617T106Q trades isolation and size for broader distributor availability in older package formats.

FAQ
What is the maximum operating frequency supported by the 2SC4965YV-TL-E?
The 2SC4965YV-TL-E achieves –40 dB signal reduction at 500 MHz and maintains usable gain up to ~2.4 GHz (fT), making it suitable for VHF (30–300 MHz) and UHF (300–1000 MHz) switching. Performance beyond 1 GHz degrades due to rising Cob and reduced hFE; actual usable bandwidth depends on PCB layout and matching network design.
Can the 2SC4965YV-TL-E replace a PIN diode in RF switch designs?
Yes, the 2SC4965YV-TL-E serves as an active alternative to PIN diodes in low-to-medium power RF switches. Unlike passive PIN diodes, it requires base bias but delivers lower Ron (1.2 Ω vs. typical 2–5 Ω) and eliminates DC blocking capacitors. The 2SC4965YV-TL-E is not a drop-in replacement-base drive circuitry and thermal layout must be redesigned.
What is the recommended base drive circuit for the 2SC4965YV-TL-E?
The 2SC4965YV-TL-E is characterized with 2.5 mA base current for Ron testing. A standard 2.7 kΩ pull-up resistor to 5 V provides this current. For faster switching, a push-pull base driver (e.g., dual-NMOS) can reduce transition time, but layout must minimize base inductance to avoid oscillation in the 200–500 MHz band where fT rolls off.
Is the 2SC4965YV-TL-E suitable for automotive applications?
No-the 2SC4965YV-TL-E carries Renesas' "Standard" quality grade, rated for office equipment, communications gear, and consumer electronics-not transportation or safety-critical systems. Its specified operating ambient range is –55°C to +150°C, but qualification data for AEC-Q101 or automotive temperature cycling is not published. Use only in non-automotive RF modules.
How does the 2SC4965YV-TL-E's thermal performance compare to larger-package RF transistors?
The 2SC4965YV-TL-E's 100 mW PC rating and 120 mW derated value at 25°C reflect its SC-70 thermal resistance (θJA ≈ 125°C/W). Compared to SOT-23 or SOT-323 devices, it offers similar power handling per unit area but requires careful PCB copper pour (≥10 mm² thermal pad) to sustain continuous 80 mA IC. Junction temperature must stay ≤150°C under worst-case RF duty cycle.
