Product details

Overview

STTH6010W from STMicroelectronics is an ultrafast recovery, high-voltage silicon rectifier diode in DO-247 package, rated for 1000 V repetitive peak reverse voltage (V_RRM), 60 A average forward current (I_F(AV)), and 49 ns typical reverse recovery time (t_rr) at 125°C under high dI/dt conditions. It serves as a primary freewheeling or output rectifier in industrial switch-mode power supplies and motor drive snubber circuits.

For engineers reviewing the STTH6010W datasheet, STTH6010W pinout, STTH6010W application, or STTH6010W equivalent, key selection criteria include soft reverse recovery (S = 1), low conduction loss (V_F = 1.3 V @ 150°C), high junction temperature capability (T_j = 175°C), and rugged surge rating (I_FSM = 400 A).

Technical Context

This diode employs a platinum-doped lifetime-controlled silicon structure to achieve ultrafast, soft recovery with minimal reverse recovery current (I_RM = 31–40 A) and controlled tail current decay. Its softness factor (S = 1) ensures reduced EMI and lower voltage overshoot during commutation.

The device is optimized for high-frequency hard-switched topologies operating up to several hundred kHz, where low switching losses (t_rr = 49 ns typ., Q_rr = ~5 µC) and thermal robustness (R_th(j-c) = 0.78 °C/W) are critical for efficiency and reliability in continuous-duty industrial systems.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	1000 V - Supports DC bus voltages up to 700 V in three-phase rectification with safety margin
I_F(AV)	60 A @ T_c = 75°C - Sustains continuous conduction in high-power SMPS output stages
t_rr (typ)	49 ns @ I_F = 60 A, dI/dt = −200 A/µs, V_R = 600 V, T_j = 125°C - Enables stable operation in >200 kHz converters
V_F (typ)	1.3 V @ I_F = 60 A, T_j = 150°C - Minimizes conduction loss and thermal stress under full load
S (Softness)	1 - Ensures smooth current zero-crossing without oscillatory ringing or voltage spikes
T_j(max)	175°C - Allows compact heatsinking and extended lifetime in sealed enclosures
R_th(j-c)	0.78 °C/W - Enables direct mounting to heatsink with predictable thermal resistance

Pinout & Package

STTH6010W uses the DO-247 through-hole package with two terminals: anode and cathode. The case is electrically isolated and designed for mechanical torque mounting (0.80 Nm recommended). Thermal performance relies on conductive cooling via the metal tab.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Forward current entry point	Connected to AC input or switching node; must withstand pulsed surge (I_FRM = 450 A)
Cathode	Forward current exit / reverse blocking terminal	Connected to DC output rail; carries full load current and blocks 1000 V reverse bias

Key Features

Feature	Design Value
Ultrafast soft recovery	49 ns t_rr with S = 1 reduces EMI and snubber stress in hard-switched PFC and inverters
High junction temperature rating	175°C max T_j enables operation in thermally constrained industrial environments without derating
Low leakage current	20 µA @ 25°C, ≤200 µA @ 125°C - Improves thermal runaway margin in parallel configurations
Rugged surge capability	400 A non-repetitive surge (10 ms sine) supports motor-start transients and line surges
ECOPACK® lead-free construction	Meets RoHS and JEDEC JESD97 standards; marked on package and inner box label

Applications

Industrial Power Supply Rectification

Motor Drive Freewheeling

Use Scenario: Output rectification in 3 kW three-phase telecom or server SMPS with 400–600 V DC bus.

IC Role / Device Role / Timing Role: Primary unidirectional current path converting transformer secondary AC to regulated DC; handles 60 A continuous and 450 A pulsed current.

Use Value: Low V_F (1.3 V) and soft recovery minimize conduction loss and reduce snubber component count and size.

Use Scenario: Freewheeling path across IGBTs in 7.5 kW variable-frequency drives for HVAC compressors.

IC Role / Device Role / Timing Role: Provides low-loss return path during IGBT turn-off; clamps inductive kickback with controlled dI/dt.

Use Value: 49 ns t_rr and S = 1 prevent voltage overshoot beyond 1200 V, eliminating need for TVS clamping.

Snubber Network Diode

Bootstrap Circuit Diode

Use Scenario: RCD snubber across flyback transformer primary in 1.5 kW industrial auxiliary supply.

IC Role / Device Role / Timing Role: Rapidly conducts stored energy during MOSFET turn-on; blocks reverse voltage during turn-off.

Use Value: Fast t_rr and low Q_rr (~5 µC) limit snubber dissipation and improve efficiency by >1.2%.

Use Scenario: High-side gate driver bootstrap diode in half-bridge motor control ICs driving 30 A BLDC motors.

IC Role / Device Role / Timing Role: Charges bootstrap capacitor during low-side conduction; blocks high-side floating rail voltage (up to 600 V).

Use Value: 1000 V V_RRM and 175°C T_j ensure reliable charge transfer even under high ambient temperatures.

Equivalent & Alternatives

The following parts are listed as comparable options for similar ultrafast high-voltage diode applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IXYS MUR6010CT	TO-247 package, dual common-cathode configuration; t_rr = 60 ns (typ), V_F = 1.45 V @ 60 A	Requires dual-diode layout; higher V_F increases conduction loss in single-diode topologies	Prefer when dual-channel layout exists or paralleling is needed
Vishay VS-60EWH10	DO-247 package, same pinout; t_rr = 55 ns (typ), V_F = 1.35 V @ 60 A, T_j(max) = 150°C	Limited to 150°C junction temperature - requires larger heatsink above 125°C ambient	Acceptable for lower-temperature environments but not drop-in for 175°C-rated designs

Compared with MUR6010CT and VS-60EWH10, STTH6010W offers superior thermal margin (175°C vs. 150°C), lower V_F, and softer recovery-making it optimal for compact, high-reliability industrial power stages where thermal headroom and EMI control are critical.

FAQ

What is the maximum allowable case temperature for continuous operation?

The STTH6010W is rated for I_F(AV) = 60 A at T_c = 75°C. With R_th(j-c) = 0.78 °C/W and T_j(max) = 175°C, the theoretical maximum case temperature is 127°C under full load. However, derating per ST's thermal curves is required above 75°C to maintain reliability and avoid exceeding junction limits.

Does STTH6010W support parallel operation?

Yes-its low and tightly controlled leakage current (20 µA @ 25°C, ≤200 µA @ 125°C) and matched forward voltage characteristics enable stable current sharing. Use matched V_F lots and symmetrical PCB layout with individual current-sense resistors for optimal balancing in parallel configurations.

Can STTH6010W replace standard fast recovery diodes in existing 100 kHz PFC designs?

Yes-its 49 ns t_rr and soft recovery significantly reduce switching losses and EMI compared to standard FRDs (typically >100 ns). No circuit redesign is needed, but verify snubber sizing and gate drive strength, as lower Q_rr may increase dV/dt stress on adjacent switches.

Is the DO-247 package compatible with automated through-hole assembly?

Yes-the DO-247 footprint is standardized for wave soldering and selective soldering processes. ST specifies 0.80 Nm recommended torque for mechanical mounting, and the epoxy body meets UL94 V0 flammability rating. Lead-free solder profiles compliant with JEDEC J-STD-020 are supported.
