Product details
Overview
PE2BB from Taiwan Semiconductor is a 2 A, 100 V ultra-fast surface-mount rectifier 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. It serves as a high-efficiency freewheeling or snubber diode in DC/DC converters operating up to several hundred kHz.
For engineers reviewing the PE2BB datasheet, PE2BB pinout, PE2BB application, or PE2BB equivalent, key selection criteria include its 100 V repetitive peak reverse voltage, low 18 °C/W junction-to-lead thermal resistance, 30 pF junction capacitance at 4 V, and suitability for automated SMT assembly with J-STD-020 Level 1 moisture sensitivity rating.
Technical Context
The PE2BB employs planar silicon technology to achieve ultra-fast switching with trr ≤ 20 ns under IF = 0.5 A / IR = 1.0 A / Irr = 0.25 A conditions and Qrr = 17.4 nC. Its single-die configuration supports unidirectional conduction with cathode band polarity marking.
Thermal performance is characterized by RθJL = 18 °C/W and RθJA = 67 °C/W on a 10 mm × 10 mm copper pad PCB, enabling reliable operation up to TJ = 175 °C. The device exhibits VF = 0.72 V at 2 A and 125 °C, confirming stable forward conduction across industrial temperature range.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R010DJF | 100 V VRRM, 2 A IF, trr = 25 ns, DO-214AA, VF = 0.92 V @ 2 A | Slightly higher VF and trr increase conduction and switching loss in >300 kHz designs | Acceptable where 5 ns trr margin is not critical and ST sourcing preferred |
| ES2D | 200 V VRRM, 2 A IF, trr = 35 ns, DO-214AA, VF = 0.95 V @ 2 A | Higher voltage rating but slower recovery and higher VF reduce efficiency in 100 V systems | Only suitable if system requires 200 V margin; otherwise PE2BB offers better dynamic performance |
Compared with STTH2R010DJF and ES2D, the PE2BB delivers superior high-frequency efficiency due to its 20 ns trr and 0.87 V VF, making it optimal for compact, thermally constrained DC/DC converters where loss budget is tight.

FAQ
What is the maximum junction temperature rating for PE2BB?
The PE2BB has a maximum junction temperature (TJ) rating of +175 °C, verified per absolute maximum ratings table. This allows sustained operation in enclosed industrial environments where ambient temperatures exceed 85 °C, provided thermal design meets RθJA = 67 °C/W on a 10 mm × 10 mm Cu pad. Derating curves confirm usable current capacity down to 1.2 A at 125 °C ambient.
Does PE2BB have a specified reverse recovery charge (Qrr)?
Yes, the PE2BB specifies Qrr = 17.4 nC under IF = 2.0 A, di/dt = 200 A/µs, VR = 100 V conditions. This value is measured and published in the Electrical Specifications table and directly impacts snubber loss calculation and EMI filter sizing in high-frequency converters using the PE2BB.
Is PE2BB compatible with lead-free reflow soldering profiles?
Yes, the PE2BB uses matte tin-plated leads compliant with J-STD-002 and is rated for standard IPC/JEDEC J-STD-020 Level 1 moisture sensitivity. It supports peak reflow temperatures up to 260 °C and is qualified for Pb-free soldering without preconditioning or special handling.
What is the cathode marking method on PE2BB?
The PE2BB uses a visible cathode band on the molded plastic body to indicate polarity, consistent with DO-214AA mechanical standard. This band aligns with the cathode terminal and must be oriented toward the positive output rail or clamp capacitor in circuit layout-critical for correct freewheeling path establishment in the PE2BB application.
How does PE2BB's forward voltage compare at elevated temperature?
At TJ = 125 °C, the PE2BB exhibits VF = 0.72 V @ 2 A, which is 0.15 V lower than its 25 °C value of 0.87 V. This negative temperature coefficient improves thermal stability in parallel configurations and reduces conduction loss under high-temperature load conditions typical in the PE2BB deployment.
