Product details
Overview
PE2DBH 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 AEC-Q101 qualification for automotive-grade reliability. It serves as a primary output rectifier in high-frequency DC/DC converters and snubber circuits where low conduction loss and fast switching are critical.
For engineers reviewing the PE2DBH datasheet, PE2DBH pinout, PE2DBH application, or PE2DBH equivalent, key selection criteria include its 200 V repetitive peak reverse voltage, 50 A surge current rating, junction-to-lead thermal resistance of 18 °C/W, and compatibility with automated SMT assembly on standard PCB pads.
Technical Context
The PE2DBH employs planar silicon technology to achieve ultra-fast recovery (trr ≤ 20 ns) and low forward voltage (VF = 0.87 V @ 2 A, 25°C), enabling high-efficiency operation in switching power supplies above 100 kHz. Its single-die configuration and DO-214AA package support compact layout and thermal management via copper pad conduction.
AEC-Q101 qualification confirms robustness under automotive temperature cycling (-55°C to +175°C TJ), while moisture sensitivity level 1 (per J-STD-020) and matte tin-plated leads ensure reliable reflow soldering without baking or special handling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum repetitive reverse blocking voltage; defines safe operating limit in flyback or active clamp snubber circuits. |
| IF | 2 A continuous - Rated average forward current; supports sustained load in 12–48 V DC/DC outputs up to ~25 W. |
| trr | 20 ns - Reverse recovery time at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; enables stable operation at ≥500 kHz switching frequencies. |
| VF @ 2A/25°C | 0.87 V max - Forward voltage drop; contributes <1.74 W conduction loss per diode at full load, reducing heatsink requirements. |
| RθJL | 18 °C/W - Junction-to-lead thermal resistance; allows direct heat transfer to PCB copper, supporting >1.5 W dissipation on 10 mm × 10 mm Cu pad. |
| Qrr | 17.4 nC - Reverse recovery charge; minimizes switching losses and EMI generation during turn-off in hard-switched topologies. |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-2EY20 | Same DO-214AA package, 2 A/200 V, but trr = 35 ns (vs. PE2DBH's 20 ns); VF = 0.92 V @ 2 A. | Higher switching loss in >300 kHz designs; suitable for lower-frequency flyback or PFC boost stages. | Prefer PE2DBH where trr-critical timing or EMI reduction is required. |
| ON Semiconductor MUR220 | DO-214AC (SMA) package, smaller footprint; 2 A/200 V, trr = 35 ns, VF = 0.95 V @ 2 A. | Lower thermal mass and higher RθJA (100 °C/W vs. PE2DBH's 67 °C/W); limited to <1.2 W dissipation. | Choose PE2DBH for higher power density and better thermal performance on standard SMB pads. |
Compared with VS-2EY20 and MUR220, the PE2DBH delivers superior high-frequency performance due to its 20 ns trr and lower VF, while its DO-214AA package and 18 °C/W RθJL enable more robust thermal management in automotive and industrial power supplies.

FAQ
What is the maximum junction temperature rating for the PE2DBH?
The PE2DBH has a maximum junction temperature (TJ) rating of +175°C, verified per AEC-Q101 stress testing. This allows operation in under-hood automotive environments and high-ambient industrial settings. Derating begins above 125°C ambient, and thermal design must maintain TJ ≤ 175°C under worst-case load and airflow conditions using the specified RθJL = 18 °C/W path.
Is the PE2DBH pin-compatible with other DO-214AA rectifiers like the MUR220?
No - while both PE2DBH and MUR220 use DO-214AA (SMB) packages, the MUR220 is actually packaged in DO-214AC (SMA), which has smaller dimensions and different pad layout. The PE2DBH matches true DO-214AA mechanical outlines per JEDEC issue D, including 4.60 mm length and 3.95 mm width, ensuring correct fit on SMB-designated footprints.
Does the PE2DBH support lead-free reflow soldering per J-STD-020?
Yes - the PE2DBH features matte tin-plated leads qualified per J-STD-002 for solderability and meets J-STD-020 moisture sensitivity level 1, meaning it can be placed directly into standard lead-free reflow profiles (peak 260°C) without pre-baking. Its UL 94V-0 molding compound also withstands multiple reflow cycles without delamination.
How does the PE2DBH's reverse recovery charge compare to standard fast recovery diodes?
The PE2DBH specifies Qrr = 17.4 nC, measured under IF = 2.0 A, di/dt = 200 A/µs, VR = 100 V. This is approximately 40% lower than typical Qrr values (≥30 nC) of legacy FRD diodes like the BYV26E, directly reducing turn-off loss and associated EMI in high-frequency converters where switching occurs above 200 kHz.
Can the PE2DBH be used in place of the PE2BBH in a design?
Yes - the PE2DBH shares identical package (DO-214AA), thermal characteristics (RθJL = 18 °C/W), and forward parameters (IF = 2 A, VF ≈ 0.87 V) with the PE2BBH, differing only in VRRM (200 V vs. 100 V). Substituting PE2DBH provides higher reverse voltage margin without layout or thermal changes, provided system transients justify the 200 V rating.
