Product details

Overview

TPUH6JH from Taiwan Semiconductor is a 600 V, 6 A ultrafast recovery rectifier diode in TO-277 package, with 50 ns reverse recovery time (t_rr), 1.85 V forward voltage (V_F) at 6 A, and 150 °C maximum junction temperature - used in high-frequency PFC stages and auxiliary power supplies.

For engineers reviewing the TPUH6JH datasheet, TPUH6JH pinout, TPUH6JH application, or TPUH6JH equivalent, key selection criteria include reverse recovery performance under 100 kHz–1 MHz switching, thermal derating above 100 °C, and compatibility with surface-mount reflow profiles for industrial SMPS designs.

Technical Context

The TPUH6JH employs a platinum-doped silicon epitaxial structure to achieve ultrafast soft recovery with low reverse recovery charge (Q_rr = 35 nC typical at I_F = 6 A, V_R = 400 V, dI/dt = 100 A/μs). Its design targets reduced EMI and switching losses in continuous conduction mode (CCM) boost PFC circuits.

Thermal performance is defined by R_θJA = 50 °C/W (standard FR-4, 1 in² copper pad) and R_θJC = 1.5 °C/W (junction-to-case), enabling operation up to 150 °C junction temperature with appropriate PCB copper area and airflow.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	600 V - maximum repetitive peak reverse voltage; supports 400 V AC input rectification with safety margin in universal-input PFC.
I_F(AV)	6 A - average forward current at T_C = 110 °C; requires ≥1.5 in² 2-oz copper for full-rated conduction.
t_rr	50 ns - measured at I_F = 1 A, I_R = 1 A, dI/dt = 100 A/μs; enables stable operation up to 1 MHz switching frequency.
V_F	1.85 V @ I_F = 6 A, T_J = 25 °C - forward drop directly impacts conduction loss and thermal rise in high-current paths.
Q_rr	35 nC typical @ I_F = 6 A, V_R = 400 V, dI/dt = 100 A/μs - low stored charge reduces turn-off spike and snubber stress.
T_J max	150 °C - maximum junction temperature; allows operation in sealed enclosures with limited airflow when properly heatsinked.

Pinout & Package

TO-277 (SMP) molded plastic package per JEDEC standard: single-side heat-sinkable surface-mount outline with cathode indicator band; case serves as cathode terminal.

Pin/Terminal	Circuit Role	Design Meaning
Anode (Lead 1)	Forward current entry point	Connected to AC input or switch node; must withstand surge currents up to 80 A (8.3 ms half-sine).
Cathode (Case)	Forward current exit / heat path	Electrically and thermally connected to PCB copper pour; requires solder mask opening and thermal vias for R_θJA optimization.

Key Features

Feature	Design Value
Ultrafast soft recovery	50 ns t_rr with low Q_rr minimizes voltage overshoot and EMI during diode turn-off in hard-switched converters.
Platinum-doped silicon	Enables consistent t_rr stability across temperature (25–125 °C) without significant increase in V_F.
TO-277 surface-mount package	Low-profile (1.4 mm height), high-current capable package compatible with automated pick-and-place and reflow soldering.
150 °C junction rating	Supports operation in high-ambient environments (e.g., enclosed LED drivers, industrial PLC power modules) without forced cooling.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH6L06D	600 V, 6 A, t_rr = 60 ns, V_F = 1.9 V @ 6 A - slightly higher recovery time and forward drop.	Designed for automotive-grade reliability; qualified to AEC-Q101 but larger TO-220AC package.	Prefer TPUH6JH for space-constrained SMT designs; STTH6L06D where automotive qualification or through-hole assembly is required.
ES6J	600 V, 6 A, t_rr = 75 ns, V_F = 1.7 V @ 6 A - lower V_F but slower recovery and no 150 °C rating.	Optimized for cost-sensitive consumer adapters; rated only to 125 °C junction temperature.	Choose TPUH6JH for high-temp industrial use; ES6J where lower conduction loss dominates and ambient stays ≤60 °C.

Compared with STTH6L06D and ES6J, the TPUH6JH delivers superior thermal capability (150 °C vs. 125–175 °C), tighter t_rr consistency across temperature, and a surface-mount footprint that reduces board area by 65% versus TO-220AC alternatives.

FAQ

What is the maximum surge current rating for TPUH6JH?

The TPUH6JH is rated for 80 A non-repetitive peak forward surge current (I_FSM) using an 8.3 ms single half-sine wave test condition. This rating applies at T_J = 25 °C and validates its suitability for inrush current handling in AC-DC front-end stages without additional series limiting.

Does TPUH6JH have a specified reverse recovery charge (Q_rr) value?

Yes, the TPUH6JH has a typical reverse recovery charge of 35 nC measured at I_F = 6 A, V_R = 400 V, and dI/dt = 100 A/μs. This low Q_rr contributes directly to reduced switching losses and EMI in high-frequency PFC circuits.

Is TPUH6JH compatible with lead-free reflow soldering processes?

Yes, the TPUH6JH TO-277 package is qualified for lead-free reflow soldering per J-STD-020, with a peak reflow temperature of 260 °C for 30 seconds. The molding compound and internal wire bonds meet IPC/JEDEC standards for thermal cycling reliability.

What is the thermal resistance from junction to case (R_θJC) for TPUH6JH?

The TPUH6JH has a junction-to-case thermal resistance of 1.5 °C/W when mounted on a standard 1 in² copper pad with 2-oz copper thickness. This value assumes full case contact and is critical for calculating allowable power dissipation in thermally constrained layouts.

How does the marking code on TPUH6JH identify the date code?

The TPUH6JH marking includes a 3-character code: first two characters (e.g., "YW") represent the year-week date code per Taiwan Semiconductor's internal system, and the third character ("F") identifies the manufacturing factory. Full decoding requires referencing TSC's published marking guide revision B2309.
