Nexperia USA Inc. PMBD6050,235

Overview

PMBD6050 from Nexperia is a high-speed switching diode in SOT23 package, designed for fast signal routing and clamping in compact analog and digital circuits. It delivers 4 ns reverse recovery time, 70 V continuous reverse voltage, 500 mA peak forward current, and 1.5 pF junction capacitance at 0 V - enabling use in RF detector stages and high-frequency sample-and-hold circuits.

For engineers reviewing the PMBD6050 datasheet, PMBD6050 pinout, PMBD6050 application, or PMBD6050 equivalent, key selection criteria include reverse recovery speed under 10 mA switching conditions, low capacitance at zero bias, thermal resistance to ambient (500 K/W), and compatibility with FR4 PCB layouts in space-constrained SMD designs.

Technical Context

The PMBD6050 employs planar silicon technology optimized for minimal carrier storage, achieving sub-4 ns trr with 10 mA IF→IR transition and 100 Ω load. Its anode–cathode–NC pin configuration isolates unused terminal to reduce parasitic coupling in high-density routing.

Thermal performance is defined for FR4 mounting: junction-to-ambient Rth(j-a) = 500 K/W and junction-to-tie-point Rth(j-tp) = 330 K/W, supporting operation up to 150 °C junction temperature with derated forward current above 50 °C ambient.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-speed switching diode applications.

Compared with BAT54C and 1N4148W, the PMBD6050 uniquely balances 70 V VR, 1.5 pF capacitance, and SOT23 size - making it optimal for space-limited, medium-voltage RF and logic protection where both speed and layout density matter.

FAQ

Is PMBD6050 suitable for bidirectional signal clamping?

No - the PMBD6050 is a unidirectional diode with dedicated anode (pin 1) and cathode (pin 3); pin 2 is not connected. For bidirectional clamping, two devices must be used in series-opposed configuration, or a dedicated dual-diode package like PESD5V0S1BA should be selected.

What is the maximum continuous forward current at 85 °C ambient?

Per Figure 2 in the datasheet, the maximum permissible continuous forward current at Tamb = 85 °C is approximately 120 mA when mounted on FR4. This derating ensures junction temperature remains below 150 °C given Rth(j-a) = 500 K/W and Ptot = 250 mW limit.

Can PMBD6050 replace 1N4148 in high-frequency circuits?

Yes - with qualification: PMBD6050 matches 1N4148's 4 ns trr but offers lower capacitance (1.5 pF vs. ~4 pF) and tighter SOT23 footprint. However, its 70 V VR is lower than 1N4148's 100 V, so voltage margin must be verified per circuit.

Does pin 2 require PCB trace routing or grounding?

No - pin 2 is internally not connected and must remain un-routed on the PCB. Adding copper or vias to pin 2 may induce mechanical stress or parasitic coupling; standard SOT23 land pattern assumes no connection to terminal 2.
