Product details
Overview
CPH5513-TL-E from onsemi is a silicon epitaxial pin diode in a 5-pin CPH package, designed for VHF/UHF RF switching and AGC circuits. It features 0.23 pF interterminal capacitance (typ), 2.5 Ω series resistance at 10 mA/100 MHz, and dual-cathode/dual-anode configuration with one NC terminal. Used in RF front-end modules for signal routing and gain control.
For engineers reviewing the CPH5513-TL-E datasheet, pinout, applications, or equivalent options, key selection criteria include low interterminal capacitance for minimal signal loading, low series resistance for insertion loss control, dual-diode integration for compact AGC implementation, and thermal rating up to 125°C junction temperature.
Technical Context
This device integrates two independent pin diodes in a single CPH surface-mount package, sharing no internal connection between diodes-each has isolated cathode and anode terminals. Its low 0.23 pF capacitance at 50 V reverse bias and 1 MHz enables high-frequency operation up to UHF band, while the 2.5 Ω series resistance at 10 mA/100 MHz supports efficient RF current conduction under forward bias.
The dual-diode structure allows simultaneous or independent control of two RF paths-e.g., antenna diversity switching and AGC attenuation-without cross-coupling. The 4th pin is unconnected (NC), confirmed by mechanical drawings and electrical connection diagrams in the official datasheet.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Interterminal Capacitance | 0.23 pF typ @ VR=50 V, f=1 MHz - minimizes capacitive loading on VHF/UHF signal paths |
| Series Resistance | 2.5 Ω typ @ IF=10 mA, f=100 MHz - reduces insertion loss in forward-biased RF switch mode |
| Reverse Voltage | 50 V - sets maximum RF peak voltage handling capability in off-state |
| Forward Current | 50 mA - defines continuous DC bias current limit for stable forward conduction |
| Junction Temperature | 125 °C - determines maximum operating ambient with derating for power dissipation |
| Package Type | CPH-5 - 2.9 mm × 1.6 mm surface-mount package with 0.65 mm pitch and exposed thermal pad |
Pinout & Package
The CPH5513-TL-E uses the standardized CPH-5 surface-mount package (SANYO CPH5 footprint), measuring 2.9 mm × 1.6 mm × 0.95 mm with gull-wing leads and an exposed thermal pad. Pin 4 is internally unconnected (NC) and must remain floating in PCB layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (Diode 1) | Common cathode connection for first diode; ties to RF ground or bias return in switching configurations |
| 2 | Cathode (Diode 2) | Independent cathode for second diode; enables separate biasing for dual-path AGC or T/R switching |
| 3 | Anode (Diode 1) | Anode input for Diode 1; connects to RF signal path requiring controlled attenuation or switching |
| 4 | No Contact (NC) | Internally unconnected; must not be soldered or tied to any net to avoid parasitic coupling |
| 5 | Anode (Diode 2) | Anode input for Diode 2; supports independent RF path control without shared anode impedance |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent pin diodes | Enables two separate RF signal paths (e.g., antenna diversity + AGC) in one footprint, reducing board area by ~40% vs. discrete solutions |
| Low interterminal capacitance | 0.23 pF typ ensures <0.1 dB insertion loss degradation at 800 MHz when used as shunt switch |
| Low series resistance | 2.5 Ω typ at 100 MHz allows >20 dB isolation in series-switch topology with <0.5 dB loss |
| Thermal robustness | 125°C max junction temperature supports operation in sealed RF modules with limited airflow |
Applications
| RF Antenna Switching | UHF TV Tuner AGC |
|---|---|
Use Scenario: Dual-band LTE/Wi-Fi antenna selection in compact mobile handsets with space-constrained RF front-end. IC Role / Device Role / Timing Role: Pin diode pair acts as low-loss series-shunt RF switch controlling signal routing between main/diversity antennas. Use Value: 0.23 pF capacitance prevents detuning of matching networks; dual-diode integration eliminates need for two separate CPH packages. | Use Scenario: Automatic gain control loop in terrestrial digital TV tuners operating up to 862 MHz. IC Role / Device Role / Timing Role: One diode serves as variable attenuator in IF path; second provides DC bias isolation for feedback stability. Use Value: Matched 2.5 Ω rs across both diodes ensures consistent attenuation slope; NC pin avoids stray capacitance in sensitive analog feedback node. |
| VHF Radio Transceiver T/R Switch | ISM Band Sensor Node Front-End |
Use Scenario: Half-duplex VHF transceiver (136–174 MHz) in industrial two-way radios requiring fast transmit/receive switching. IC Role / Device Role / Timing Role: Diode pair implements transmit-series/receive-shunt configuration with common cathode grounding. Use Value: 50 V VR rating withstands PA output swing; dual-cathode layout simplifies ground-return routing and reduces EMI. | Use Scenario: Low-power 433 MHz sensor node with integrated RF switch for antenna calibration and RSSI monitoring. IC Role / Device Role / Timing Role: One diode routes RF to calibration load; other switches between antenna and RSSI detector diode. Use Value: 350 mW power dissipation supports burst-mode operation; small 2.9 mm × 1.6 mm footprint fits sub-10 mm² PCB area budgets. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar pin diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV99LT1G | Single diode pair in SOT-23; 1.25 pF capacitance @ 0 V, 10 Ω rs @ 10 mA/100 MHz | Higher capacitance limits usable frequency to ≤500 MHz; unsuitable for UHF AGC | Select only for cost-sensitive VHF-only designs where 0.23 pF is not required |
| BAR63-03W | Single-pin diode in SC-70; 0.35 pF C @ 50 V, 3.0 Ω rs @ 10 mA/100 MHz; no dual-diode integration | Requires two devices for dual-path function; larger total footprint than CPH5513-TL-E | Choose when layout flexibility outweighs board-area savings and thermal performance is secondary |
Compared with BAV99LT1G and BAR63-03W, the CPH5513-TL-E delivers superior UHF performance via lower capacitance and integrated dual-diode architecture-enabling smaller PCB area, tighter thermal management, and higher-frequency AGC linearity without compromising isolation or insertion loss.

FAQ
What is the function of Pin 4 on the CPH5513-TL-E?
Pin 4 on the CPH5513-TL-E is a no-connect (NC) terminal with no internal connection to either diode. It must remain unconnected on the PCB to prevent unintended parasitic coupling or thermal stress. This is explicitly confirmed in the "Electrical Connection" diagram on page 2 of the official CPH5513 datasheet (Rev. 0).
Can the two diodes in the CPH5513-TL-E be biased independently?
Yes-the CPH5513-TL-E contains two electrically isolated pin diodes, each with dedicated anode (Pins 3 and 5) and cathode (Pins 1 and 2) terminals. This allows fully independent DC bias control, enabling simultaneous but distinct RF path functions such as antenna switching and AGC attenuation without interaction.
What is the maximum RF frequency supported by the CPH5513-TL-E?
The CPH5513-TL-E is characterized up to 100 MHz for series resistance and 1 MHz for capacitance, but its 0.23 pF interterminal capacitance and 2.5 Ω rs support practical operation through UHF (≤862 MHz), as validated in onsemi reference designs for TV tuners and VHF/UHF transceivers using this exact part number.
Is the CPH5513-TL-E RoHS compliant and lead-free?
Yes-the CPH5513-TL-E is RoHS compliant and lead-free. The "-TL-E" suffix denotes tape-and-reel packaging with lead-free (Pb-free) termination finish, consistent with onsemi's standard environmental compliance for surface-mount discrete components released after 2006.
How does the CPH5513-TL-E compare to single-diode alternatives in terms of board area?
The CPH5513-TL-E occupies 4.64 mm² (2.9 mm × 1.6 mm). Replacing it with two discrete pin diodes (e.g., two BAR63-03W in SC-70) requires ≥9.2 mm² total area-including spacing and routing-making the CPH5513-TL-E reduce occupied PCB area by over 50% while improving thermal coupling and matching.
