This combination — high voltage in a small outline — targets applications where a 40 V or 80 V general-purpose PNP won't survive: offline auxiliary supplies, telecom line drivers, 48 V industrial bus interfaces, and the high-side drive stage in half-bridge gate drivers where a PNP pulls the gate high. The 100 MHz transition frequency keeps switching losses manageable up to a few hundred kilohertz, though the 500 mV saturation at 20 mA means it is not a low-dropout switch — the buyer should calculate the on-state voltage drop against the load current before committing the BOM line. ## Package and thermal reality Without a thermal via stitch under the tab, the practical continuous dissipation at 85 °C ambient drops to roughly half the rated number — the board layout engineer should budget copper area on the collector tab pad. The 150 °C junction temperature rating gives some headroom for pulsed operation, but steady-state current above 100 mA needs a thermal check against the actual ambient. ## Switching or linear — the Vce(sat) and hFE tell the story The 500 mV saturation voltage at 20 mA is typical for a high-voltage PNP — it is not a 100 mV saturation part, so the designer should verify that the collector-emitter drop at the load current does not steal too much voltage from the load. The 100 nA maximum collector cutoff current is tight enough for high-impedance nodes in analog bias circuits.","metaTitle":"Infineon BFN39H6327 PNP Transistor, 300 V, 0.2 A, SOT-223","metaDescription":"Infineon BFN39H6327 PNP transistor: 300 V Vce breakdown, 200 mA Ic, 100 MHz fT, 1.5 W max power, SOT-223 surface mount.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"Not applicable","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Package":"Bulk","Power - Max":"1.5 W","Mounting Type":"Surface Mount","Package / Case":"TO-261-4, TO-261AA","Transistor Type":"PNP","lifecycle_stage":"eol_hot","Operating Temperature":"150°C (TJ)","Frequency - Transition":"100MHz","Supplier Device Package":"SOT-223","Vce Saturation (Max) @ Ib, Ic":"500mV @ 2mA, 20mA","Current - Collector (Ic) (Max)":"200 mA","Current - Collector Cutoff (Max)":"100nA (ICBO)","DC Current Gain (hFE) (Min) @ Ic, Vce":"40 @ 10mA, 10V","Voltage - Collector Emitter Breakdown (Max)":"300 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.17","stockQuantity":0,"priceTiers":[{"qty":1775,"price":"$0.17000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/84b88e790d10e70d7110a0cd1aa2271d.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the Vce max for BFN39H6327?","answer":"The collector-emitter breakdown voltage is 300 V maximum.
