Product details

Overview

PE4DC from Taiwan Semiconductor is a 200V, 4A ultra-fast surface-mount rectifier in DO-214AB (SMC) package, featuring 20 ns reverse recovery time, 0.86 V forward voltage at 4A/25°C, and 130 A surge current capability-designed for high-frequency switching power supplies and snubber circuits.

For engineers reviewing the PE4DC datasheet, PE4DC pinout, PE4DC application, or PE4DC equivalent, key selection criteria include its 200 V repetitive peak reverse voltage, low 15 °C/W junction-to-lead thermal resistance, ultra-fast 16.4 ns typical reverse recovery time, and RoHS/halogen-free compliance for industrial and automotive-grade power conversion designs.

Technical Context

The PE4DC employs planar silicon technology to achieve ultra-fast switching with low stored charge (Qrr = 25.4 nC) and minimal reverse recovery current (IRM = 2.9 A), enabling efficient operation in DC/DC converters operating above 100 kHz. Its single-die configuration and DO-214AB package support automated placement and high thermal reliability up to 175 °C junction temperature.

Thermal performance is optimized for PCB mounting on 16 mm × 16 mm copper pads, delivering R_θJL = 15 °C/W and R_θJA = 56 °C/W. The device exhibits strong temperature stability: VF drops to 0.71 V at 4A/125°C, while IR remains ≤10 µA at TJ = 125°C under rated VR.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH4R02DJF	200 V V_RRM, 4 A I_F, but 35 ns t_rr (vs. PE4DC's 16.4 ns); higher Q_rr = 42 nC	Less suitable for >300 kHz designs due to slower recovery and higher switching loss	Prefer PE4DC where layout space permits and switching frequency exceeds 250 kHz
MBR4200CT	200 V dual common-cathode Schottky; zero reverse recovery but 0.95 V V_F @ 4A and 125 °C derating limit	Lower EMI but higher conduction loss and thermal limitation vs. PE4DC's 175 °C rating	Choose PE4DC for higher ambient temperature or higher efficiency at elevated load

Compared with STTH4R02DJF and MBR4200CT, the PE4DC delivers superior high-frequency performance via its 16.4 ns t_rr and 25.4 nC Q_rr, while maintaining full 175 °C junction operation and lower forward drop than Schottky alternatives at elevated temperatures-making it optimal for thermally constrained, high-switching-frequency rectification.

FAQ

What is the maximum junction temperature rating for the PE4DC?

The PE4DC has a maximum junction temperature (T_JMAX) of +175 °C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet revision A2301. This rating enables reliable operation in high-ambient environments such as enclosed industrial power supplies or under-hood automotive auxiliary converters. Derating curves confirm usable current capacity down to 0 A at 175 °C case temperature. The PE4DC must be mounted on a PCB with adequate copper area to maintain this limit under full load.

Does the PE4DC have a specified reverse recovery time (t_rr) and how is it measured?

Yes, the PE4DC specifies a typical reverse recovery time (t_rr) of 16.4 ns under conditions of I_F = 4.0 A, di/dt = 200 A/µs, and V_R = 100 V. This value is measured using standardized double-pulse test methodology per JEDEC guidelines and appears in the Electrical Specifications table of the PE4DC datasheet. The PE4DC's t_rr is significantly faster than conventional fast recovery diodes, directly supporting high-frequency switching topologies.

Is the PE4DC RoHS compliant and halogen-free?

Yes, the PE4DC is RoHS compliant and halogen-free per IEC 61249-2-21, as explicitly stated in the Features section of the Taiwan Semiconductor datasheet (version A2301). The molding compound meets UL 94V-0 flammability rating, and terminals are matte tin-plated per J-STD-002. These compliance attributes are confirmed for the PE4DC part number-not inferred from family-level statements-and apply to all units shipped under this ordering code.

What is the marking code printed on the PE4DC device body?

The PE4DC is marked "PE4DC" on its molded plastic body, as shown in the Marking Diagram on page 4 of the official datasheet (version A2301). The marking includes the part number, green compound indicator (G), factory code (F), and date code (YW), with cathode polarity indicated by a visible band. No alternate or abbreviated markings are used for the PE4DC; this exact code distinguishes it from PE4BC (marked "PE4BC") and other variants in the series.

What is the thermal resistance from junction to ambient (R_θJA) for the PE4DC and under what conditions is it measured?

The PE4DC has a junction-to-ambient thermal resistance (R_θJA) of 56 °C/W, measured with the device mounted on a standard 16 mm × 16 mm copper pad on FR4 PCB, per JEDEC test board guidelines. This value assumes natural convection cooling and is provided in the Thermal Performance table of the PE4DC datasheet (version A2301). It is not valid for bare-die or heatsink-mounted configurations. For accurate thermal design, users must reference the PE4DC's R_θJL = 15 °C/W when calculating PCB copper thermal paths.
