Product details
Overview
PE4BC from Taiwan Semiconductor is a 100V, 4A ultra-fast surface-mount rectifier diode in DO-214AB (SMC) package, featuring 20 ns reverse recovery time, 0.86 V forward voltage at 4 A/25°C, and 130 A surge current capability-designed for high-frequency switching and snubber circuits in DC/DC converters.
For engineers reviewing the PE4BC datasheet, PE4BC pinout, PE4BC application, or PE4BC equivalent, key selection criteria include its 100 V repetitive peak reverse voltage, 175 °C maximum junction temperature, low 15 °C/W junction-to-lead thermal resistance, and RoHS/halogen-free compliance for industrial power conversion designs.
Technical Context
The PE4BC employs planar silicon technology to achieve ultra-fast recovery (trr ≤ 20 ns) with low stored charge (Qrr = 25.4 nC), enabling efficient operation in high-frequency switching topologies. Its single-die configuration and DO-214AB package support automated placement and high thermal dissipation via PCB copper pads.
Electrical behavior is characterized by low forward voltage (VF = 0.86 V @ 4 A, 25°C), tight reverse leakage (IR ≤ 2 µA @ 25°C), and stable capacitance (CJ = 72 pF @ 1 MHz, 4 V), making it suitable for snubber networks and fast transient response requirements.
Key Specifications

| VF @ 4A, 25°C | 0.86 V - Forward voltage drop; directly impacts conduction loss and thermal design in high-current paths |
| RθJL | 15 °C/W - Junction-to-lead thermal resistance; enables accurate thermal modeling when mounted on 16 mm × 16 mm Cu pad |
| TJ max | +175 °C - Maximum junction temperature; allows reliable operation in high-ambient industrial environments |

IC Role / Device Role / Timing Role: Fast turn-on/turn-off to absorb voltage spikes during MOSFET turn-off; recovers before next switching cycle. Use Value: 20 ns trr and low Qrr (25.4 nC) minimize energy dissipation in snubber resistor and suppress overshoot <10% above VDS(max). |
| DC/DC Converter Freewheeling | High-Frequency Inverter Output Stage |
Use Scenario: Freewheeling path in synchronous or non-synchronous buck converters running at ≥200 kHz. IC Role / Device Role / Timing Role: Provides low-loss current recirculation path during high-side switch off-time; blocks reverse voltage during on-time. Use Value: 100 V VRRM and 175 °C TJ max allow stable operation in 48 V input systems with ambient temperatures up to 85 °C. | Use Scenario: Output rectification in high-frequency resonant inverters for induction heating or ultrasonic drivers.

Use Value: CJ = 72 pF and fast trr ensure minimal capacitive loading and clean waveform fidelity up to 500 kHz fundamental frequency. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH4R010DJF | 100 V VRRM, 4 A IF, trr = 25 ns, VF = 0.89 V @ 4 A - slightly slower and higher VF | Higher conduction loss and marginally reduced EMI suppression in snubbers | Acceptable where 5 ns trr margin is acceptable and ST sourcing is preferred |
| ON Semi MUR410E | 100 V VRRM, 4 A IF, trr = 35 ns, VF = 0.87 V @ 4 A - significantly slower recovery | Not recommended for >150 kHz switching; higher switching loss in high-frequency DC/DC | Lower-cost option only for legacy 50–100 kHz designs where trr is not critical |
Compared with STTH4R010DJF and MUR410E, the PE4BC delivers superior high-frequency performance due to its 20 ns trr and optimized Qrr, making it the preferred choice for modern compact DC/DC modules requiring minimal switching loss and thermal footprint.

FAQ
What is the maximum repetitive peak reverse voltage rating for PE4BC?
The PE4BC has a maximum repetitive peak reverse voltage (VRRM) rating of 100 V, verified per JEDEC test conditions at TA = 25°C. This rating ensures reliable blocking capability in 48 V and 60 V nominal input power systems where transient overvoltage margins are within ±20% of nominal rail.
What is the forward voltage drop of PE4BC at 4 A and 25°C?
The PE4BC exhibits a typical forward voltage drop (VF) of 0.86 V at 4 A and 25°C, with a maximum of 0.93 V under the same conditions. This value is measured using pulse testing (PW = 0.3 ms) and directly impacts conduction loss calculations in thermal design for the PE4BC.
Does PE4BC have a specified reverse recovery time, and how is it measured?
Yes, the PE4BC has a reverse recovery time (trr) of ≤20 ns, measured under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. An alternate condition (IF = 1.0 A, di/dt = 50 A/µs, VR = 30 V) yields trr = 22 ns - both values confirm its ultra-fast classification for high-frequency PE4BC applications.
Is PE4BC compatible with lead-free reflow soldering processes?
Yes, the PE4BC features matte tin-plated leads qualified per J-STD-002 for solderability and is rated for lead-free reflow profiles. Its moisture sensitivity level is Class 1 (per J-STD-020), meaning it can be stored indefinitely at ≤30°C/60% RH without baking prior to assembly - a key advantage for PE4BC manufacturing scalability.
What thermal resistance values are specified for PE4BC in its DO-214AB package?
The PE4BC specifies RθJL = 15 °C/W (junction-to-lead) and RθJA = 56 °C/W (junction-to-ambient), measured on a 16 mm × 16 mm Cu pad test board. These values enable accurate thermal modeling for PE4BC in high-power-density layouts where heatsinking is limited to PCB copper area.
