Product details

Overview

PE2DB from Taiwan Semiconductor is a 2 A, 200 V ultra-fast surface-mount rectifier diode in DO-214AA (SMB) package, featuring 20 ns reverse recovery time, 0.87 V forward voltage at 2 A/25°C, and 50 A surge current capability - deployed in high-frequency DC/DC converters and snubber circuits.

For engineers reviewing the PE2DB datasheet, PE2DB pinout, PE2DB application, or PE2DB equivalent, key selection criteria include its 200 V repetitive peak reverse voltage, ultra-fast trr ≤20 ns, low VF at elevated temperature, thermal resistance R_θJL = 18 °C/W, and SMB package compatibility with automated placement.

Technical Context

This single-die silicon rectifier uses planar technology to achieve low conduction loss and fast switching performance. Its 20 ns reverse recovery time (trr) and 17.4 nC reverse recovery charge (Q_rr) support operation in high-frequency switching topologies up to several hundred kHz.

The device operates across –55°C to +175°C junction temperature range with R_θJA = 67 °C/W on standard 10 mm × 10 mm PCB copper pad, and features matte tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance.

Key Specifications

Equivalent & Alternatives

The following parts are listed as comparable options for similar ultra-fast rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH2R02	V_RRM = 200 V, I_F = 2 A, t_rr = 25 ns, VF = 0.95 V @ 2 A - higher VF and slower recovery than PE2DB	Suitable for lower-frequency (<100 kHz) designs where efficiency margin is less critical	Choose STTH2R02 only if layout allows higher thermal dissipation or switching frequency is below 150 kHz
ES2D	V_RRM = 200 V, I_F = 2 A, t_rr = 35 ns, VF = 0.92 V @ 2 A - significantly slower and higher VF than PE2DB	Better suited for general-purpose rectification, not optimized for high-frequency snubbers or DC/DC outputs	Select ES2D only when cost is primary driver and trr < 25 ns is not required

Compared with STTH2R02 and ES2D, PE2DB delivers superior high-frequency performance due to its 20 ns t_rr and 0.87 V V_F, making it the preferred choice for compact, thermally constrained DC/DC and snubber designs demanding minimal switching loss.

FAQ

What is the maximum junction temperature rating for PE2DB?

The PE2DB has a maximum junction temperature (T_J) rating of +175°C, verified per absolute maximum ratings table. This allows operation in thermally demanding environments such as enclosed power supplies or motor drive modules. Derating curves confirm usable current capacity down to –55°C ambient, and the device maintains specified electrical parameters within this full range. PE2DB's thermal design leverages R_θJL = 18 °C/W for effective heat transfer to PCB copper.

Does PE2DB have a defined pinout or polarity marking?

Yes, PE2DB uses standard DO-214AA (SMB) polarity convention: the cathode is marked by a visible band on the molded body. The anode is the unmarked end. This polarity must be observed during PCB layout and assembly to ensure correct forward conduction and reverse blocking. No internal pin numbering applies - it is a two-terminal discrete diode, and orientation is solely defined by the cathode band per JEDEC DO-214AA specification.

What is the reverse recovery time (t_rr) specification for PE2DB, and under what test conditions?

The PE2DB reverse recovery time is specified as ≤20 ns, measured under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. An alternate condition yields t_rr = 24 ns at IF = 1.0 A, di/dt = 50 A/µs, VR = 30 V. These values are confirmed in the Electrical Specifications table. PE2DB's t_rr performance is critical for minimizing switching loss in high-frequency DC/DC converters, and the datasheet provides Q_rr = 17.4 nC to further quantify stored charge.

Is PE2DB suitable for use in RoHS-compliant and halogen-free manufacturing processes?

Yes, PE2DB is fully RoHS compliant and halogen-free per IEC 61249-2-21. Its molding compound contains no brominated flame retardants, and terminals are matte tin-plated without lead or antimony. The device carries moisture sensitivity level 1 (per J-STD-020), eliminating pre-bake requirements. PE2DB meets JESD201 Class 2 whisker resistance and J-STD-002 solderability standards - all verified in the Mechanical Data section.

How does PE2DB compare to PE2BB in terms of voltage rating and application suitability?

PE2DB is rated for 200 V repetitive peak reverse voltage (V_RRM), whereas PE2BB is rated for 100 V. Both share identical current (2 A), thermal (R_θJL = 18 °C/W), and speed (t_rr ≤20 ns) specifications. PE2DB is selected for 200 V bus applications like industrial DC/DC, telecom power, or active clamp circuits; PE2BB serves 100 V systems such as low-voltage adapters or auxiliary rails. The "x" in PE2xB denotes voltage grade, and PE2DB is the highest-voltage variant in this family.
