Frequently Asked Questions
Q1: What package does HT20340B use? Any other package versions?
A: Only TO‑247‑3L through‑hole package. No SMD, SOP‑16 or DIP‑16 variants. Thermal grease and heat sink are required for full‑power operation.
Q2: What is the operating frequency range?
A: Rated 10‑300 MHz. Gain and output power drop rapidly above 300 MHz. Operation beyond this band is not recommended.
Q3: Are there suffix variants such as HT20340A / HT20340C?
A: HT20340B is the complete part number. No official A/C suffix versions exist. Please check silkscreen upon receipt to avoid mixing‑up with similar RF transistors.
Q4: What are reference alternative parts?
A: Comparable options: BLF278, RD70HHF1. Pinout, supply voltage and gain differ. Matching network must be re‑tuned; direct drop‑in replacement is not supported.
Q5: What happens with poor heat dissipation?
A: Insufficient cooling causes high junction temperature, leading to performance degradation or permanent device burnout at 400W full power. Always apply thermal grease to heat‑sink contact surface.
Q6: Does it support both CW and pulse working modes?
A: Yes. It supports CW and pulse RF applications. Actual output power depends on heat‑sink design and system duty cycle.
Q7: How do I get datasheet, pinout or bulk quotation?
A: Submit an inquiry via our contact form. Our team will return datasheet reference, stock status and volume price within 24 hours.
Q8: Difference between HT20340B and HT20340S?
A: Both are TO‑247 family devices, but B and S suffix represent different functions with different parameters. They cannot substitute each other.
