Product details

Overview

BYC58X-600,127 from WeEn is an ultrafast recovery silicon rectifier diode rated for 600 V repetitive peak reverse voltage (V_RRM) and 8 A average forward current (I_F(AV)), with 75 ns reverse recovery time (t_rr) and low 1.85 V forward voltage drop (V_F) at 8 A. It serves as a high-efficiency output rectifier in switched-mode power supplies for industrial UPS and PV inverters.

For engineers reviewing the BYC58X-600,127 datasheet, BYC58X-600,127 pinout, BYC58X-600,127 application, or BYC58X-600,127 equivalent, key selection criteria include its ultrafast t_rr, soft recovery characteristic, junction temperature rating of 175 °C, and TO-220AC package suitability for conduction-loss-sensitive 50–100 kHz SMPS designs.

Technical Context

This diode employs planar passivated silicon technology optimized for low stored charge (Q_rr = 40 nC) and soft reverse recovery to minimize EMI generation and reduce snubber stress in hard-switched topologies. Its 175 °C maximum junction temperature supports operation in thermally constrained environments without derating below full I_F(AV).

The device exhibits a typical reverse leakage current (I_R) of 5 µA at 600 V and 25 °C, and a surge current rating (I_FSM) of 100 A (half-sine, 10 ms), enabling robust handling of transient overloads in motor drive and renewable energy front-end rectification stages.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	600 V - blocks up to 600 V reverse voltage without breakdown, suitable for 400 V DC bus systems with safety margin
I_F(AV)	8 A - continuous forward current capability at case temperature ≤ 95 °C, enabling compact heatsink design
t_rr	75 ns - ultrafast recovery minimizes switching losses and EMI in 50–100 kHz SMPS applications
V_F @ 8 A	1.85 V - low forward drop reduces conduction loss and thermal load in high-current output stages
T_j(max)	175 °C - high junction temperature rating allows reliable operation in sealed or high-ambient environments
Q_rr	40 nC - low recovered charge enables soft switching behavior and reduces voltage overshoot across switching FETs

Pinout & Package

BYC58X-600,127 is housed in a TO-220AC package with isolated tab, featuring two terminals: cathode (pin 1) and anode (pin 2). The metal tab is electrically connected to the cathode and serves as the primary heat dissipation path.

Equivalent & Alternatives

The following parts are listed as comparable options for similar ultrafast rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH8R06DJF	Same 600 V V_RRM, 8 A I_F(AV), but t_rr = 65 ns and V_F = 1.95 V; TO-220FP package with non-isolated tab	Better t_rr but higher V_F and requires insulating hardware due to tab-to-cathode short	Select when lowest possible recovery time is critical and thermal interface permits insulation
IXYS MUR860E	600 V V_RRM, 8 A I_F(AV), t_rr = 70 ns, V_F = 1.8 V; TO-220AC package with isolated tab	Nearly identical specs and mechanical form factor; Q_rr = 35 nC slightly lower	Drop-in replacement where tighter Q_rr tolerance and legacy IXYS qualification are required

Compared with STTH8R06DJF and IXYS MUR860E, BYC58X-600,127 offers balanced trade-offs: softer recovery than STTH8R06DJF (reducing EMI risk), and superior thermal interface flexibility versus MUR860E due to WeEn's standardized isolated-tab construction and AEC-Q101-aligned process control.

FAQ

What is the maximum junction temperature rating for BYC58X-600,127?

The BYC58X-600,127 has a maximum junction temperature (T_j(max)) of 175 °C. This rating allows the device to operate reliably at full 8 A average forward current with case temperatures up to 95 °C, making it suitable for thermally demanding applications such as enclosed UPS units and solar microinverters where ambient temperatures exceed 85 °C.

Is BYC58X-600,127 qualified to AEC-Q101 standards?

Yes, BYC58X-600,127 is part of WeEn's Automotive Grade Rectifiers portfolio and is qualified to AEC-Q101. This qualification confirms its suitability for automotive applications including on-board chargers (OBC), EV charging modules, and body control units where reliability under thermal cycling, humidity, and vibration is mandatory.

What is the reverse recovery time (t_rr) of BYC58X-600,127 and how is it measured?

The BYC58X-600,127 has a typical reverse recovery time (t_rr) of 75 ns, measured under conditions of I_F = 8 A, di/dt = 100 A/µs, and T_j = 25 °C. This value reflects the time required for minority carriers to recombine after forward conduction, directly impacting switching loss and EMI in high-frequency converters.

Does BYC58X-600,127 have an isolated tab in its TO-220AC package?

Yes, BYC58X-600,127 uses a TO-220AC package with electrically isolated metal tab. The tab is connected to the cathode terminal but insulated from the mounting surface, allowing direct heatsink attachment without additional insulating hardware-unlike TO-220FP variants where the tab is internally shorted to the cathode.

What is the surge current rating (I_FSM) of BYC58X-600,127 and under what conditions?

The BYC58X-600,127 has a non-repetitive peak forward surge current (I_FSM) rating of 100 A, specified for a single half-sine wave pulse of 10 ms duration at T_j = 25 °C. This rating ensures robustness against inrush currents and transient overloads in applications like PV inverter startup and motor drive fault clearing.
