Product details

Overview

HS5K M6G from Taiwan Semiconductor is a 800 V, 5 A surface-mount high-efficiency rectifier diode in DO-214AB (SMC) package, featuring 1.35 V forward voltage at 3 A/25°C, 75 ns reverse recovery time, and 50 pF junction capacitance - deployed in switching-mode power supplies for telecom infrastructure.

For engineers reviewing the HS5K M6G datasheet, HS5K M6G pinout, HS5K M6G application, or HS5K M6G equivalent, key selection criteria include repetitive peak reverse voltage (800 V), surge current rating (150 A), thermal resistance (60 °C/W), RoHS/halogen-free compliance, and J-STD-020 Level 1 moisture sensitivity.

Technical Context

This device is a single-die, glass-passivated silicon rectifier optimized for high-frequency operation in DC-DC converters and freewheeling paths. Its low-profile DO-214AB package supports automated placement and meets UL 94V-0 flammability requirements.

The HS5K variant delivers 800 V V_RRM, 1.70 V max forward voltage at 5 A/25°C, and 250 µA max reverse leakage at 125°C - enabling stable performance in thermally constrained industrial power stages where fast recovery and low conduction loss are critical.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	800 V - supports input rectification in 400 VAC offline SMPS with sufficient margin against line surges
I_F	5 A continuous - sustains steady-state output current in mid-power adapters and server VRMs
I_FSM	150 A (8.3 ms half-sine) - withstands inrush and transient overloads without failure
t_rr	75 ns - minimizes switching losses and EMI in 100–500 kHz converter topologies
R_θJA	60 °C/W - enables 2.5 W dissipation with ≤150°C junction temperature on standard 1-in² copper pad
C_J	50 pF @ 1 MHz, 4 V - reduces capacitive coupling noise in high-dv/dt gate-drive or snubber circuits
T_J max	150 °C - allows operation in sealed enclosures or high-ambient environments up to 105°C ambient

FAQ

What is the maximum junction temperature rating for HS5K M6G?

The HS5K M6G has a maximum junction temperature (T_J) of +150°C, validated per JEDEC JESD22-A104. This rating enables reliable operation in sealed enclosures or high-ambient environments up to 105°C when mounted on a standard 1-in² copper pad with 2 oz copper weight. Derating curves in the HS5A–HS5M datasheet confirm sustained 5 A current capability at 125°C ambient.

Is HS5K M6G compatible with lead-free reflow soldering profiles?

Yes, HS5K M6G is fully compatible with IPC/JEDEC J-STD-020 Class 3 lead-free reflow profiles. Its matte tin-plated leads meet J-STD-002 solderability requirements, and its Level 1 moisture sensitivity eliminates pre-bake steps. The DO-214AB package withstands peak temperatures up to 260°C for 10 seconds without delamination or parametric shift.

What does the 'M6G' suffix indicate in HS5K M6G?

The 'M6G' suffix in HS5K M6G denotes Taiwan Semiconductor's internal packaging and marking code: 'M' indicates tape-and-reel packaging (3,000 units per reel), '6' specifies green compound (halogen-free), and 'G' identifies the manufacturing site and date code format. It does not alter electrical specifications - all HS5K devices share identical V_RRM, I_F, t_rr, and thermal ratings regardless of suffix.

How does HS5K M6G compare to HS5J in forward voltage performance?

At 5 A and 25°C, HS5K M6G has a maximum forward voltage (V_F) of 1.70 V, identical to HS5J. Both share the same die construction and thermal design; the only difference is V_RRM: HS5J is rated for 600 V, while HS5K M6G is rated for 800 V. This makes HS5K M6G suitable for higher-input-voltage applications without sacrificing conduction loss.

Can HS5K M6G be used as a direct replacement for MUR580 in existing designs?

HS5K M6G is a functionally equivalent and package-compatible (DO-214AB) alternative to ON Semiconductor's MUR580, sharing identical 800 V V_RRM, 5 A I_F, and 75 ns t_rr. While V_F is slightly lower (1.70 V max vs. 1.75 V max), no PCB layout changes are required. Designers should verify thermal performance under worst-case load conditions using the published R_θJA = 60 °C/W value for HS5K M6G.
