Product details

Overview

STTH30L06W from STMicroelectronics is a 600 V, 30 A ultrafast high-voltage rectifier diode in DO-247 package, optimized for discontinuous-mode PFC boost stages and secondary-side rectification in industrial switching power supplies. It delivers 65 ns max reverse recovery time, 1.0 V typical forward voltage at 150 °C, and 1.7 °C/W max junction-to-case thermal resistance.

For engineers reviewing the STTH30L06W datasheet, STTH30L06W pinout, STTH30L06W application, or STTH30L06W equivalent, key selection criteria include ultrafast trr performance under high dIF/dt, low conduction loss at 30 A average current, thermal robustness up to 175 °C junction temperature, and DO-247 mechanical compatibility with high-power heatsink mounting.

Technical Context

The STTH30L06W employs ST's Turbo 2 silicon technology to achieve soft, ultrafast reverse recovery with 65 ns trr (max) at IF = 0.5 A, Irr = 0.25 A, and VR = 30 V. Its dynamic behavior is characterized by low IRM (11.5–16 A) and high softness factor across dIF/dt up to 500 A/µs, minimizing EMI in high-frequency PFC designs.

Static performance includes 1.0–1.25 V VF (typ/max) at 30 A and 150 °C, 80 µA IR at 150 °C/600 V, and absolute ratings of 600 V VRRM, 50 A IF(RMS), and 160 A IFSM (10 ms sine). Thermal design is supported by Rth(j-c) = 1.7 °C/W (DO-247) and Tj(max) = 175 °C.

Key Specifications

Parameter	Value and Actual Design Meaning
VRRM	600 V - Withstands repetitive reverse voltage up to 600 V in bridge or boost configurations without breakdown.
IF(AV)	30 A at Tc = 125 °C, δ = 0.5 - Sustains continuous average forward current of 30 A with proper heatsinking.
trr (max)	65 ns - Enables operation in >100 kHz PFC and SMPS topologies with minimal switching loss and voltage overshoot.
VF (typ)	1.0 V at IF = 30 A, Tj = 150 °C - Reduces conduction loss to ~30 W (P ≈ 0.95×IF + 0.010×IF²) in high-temp operation.
Rth(j-c)	1.7 °C/W - Allows direct thermal path from junction to heatsink in DO-247 package, supporting compact thermal design.
Tj(max)	175 °C - Permits reliable operation in industrial environments with elevated ambient temperatures and transient overloads.
IRM	11.5–16 A - Peak reverse recovery current remains bounded under high dIF/dt (100 A/µs), limiting snubber stress.

Pinout & Package

STTH30L06W uses the DO-247 package: a through-hole, isolated, high-power plastic case with single anode/cathode terminals and insulated creepage distance suitable for 2500 VRMS working voltage. The package features a flat tab for mechanical mounting and thermal conduction.

Pin/Terminal	Circuit Role	Design Meaning
Anode (Lead 1)	Forward current entry point	Connected to input side of boost inductor or transformer secondary; must handle 160 A surge peaks.
Cathode (Tab)	Forward current exit / heat sink interface	Electrically active cathode terminal; serves as primary thermal path to heatsink; requires insulated mounting for isolation compliance.

Key Features

Feature	Design Value
Ultrafast recovery	65 ns trr (max) enables >100 kHz PFC operation with low EMI and reduced snubber losses.
Low VF at high Tj	1.0 V typ at 30 A/150 °C lowers conduction loss by ~15% vs. standard fast diodes at elevated temperature.
Soft recovery characteristic	High softness factor (>1.0) suppresses voltage ringing and dv/dt-induced gate noise in adjacent MOSFETs.
High thermal robustness	175 °C max junction temperature and 1.7 °C/W Rth(j-c) support sustained 30 A operation in confined enclosures.
Isolated package rating	DOP3I-equivalent insulation (2500 VRMS) allows use in reinforced-isolation AC-DC front-ends without external barriers.

Applications

Industrial Switch-Mode Power Supplies

Discontinuous-Mode PFC Boost Stage

Use Scenario: High-efficiency 1–3 kW AC-DC front-end in motor drives and PLC power modules.

IC Role / Device Role / Timing Role: Secondary-side output rectifier replacing slower 600 V diodes to reduce switching loss and improve thermal margin.

Use Value: 65 ns trr cuts turn-off loss by ~40% vs. standard fast diodes, enabling smaller heatsinks and higher power density.

Use Scenario: Boost diode in 300–400 V DC-link PFC stage operating at 65–100 kHz.

IC Role / Device Role / Timing Role: Ultrafast unidirectional current path during inductor discharge phase; critical for soft recovery timing control.

Use Value: Low IRM and high softness factor prevent MOSFET shoot-through and reduce EMI filter size by 25%.

Telecom Rectifier Modules

Uninterruptible Power Supply (UPS) Output Stage

Use Scenario: -48 V DC output rectification in telecom shelf power systems with strict efficiency targets.

IC Role / Device Role / Timing Role: Primary high-current rectifier in full-wave bridge configuration handling 30 A continuous load.

Use Value: 1.0 V VF at 150 °C maintains <1.5% efficiency penalty at full load and 70 °C ambient, meeting NEBS Level 3 thermal specs.

Use Scenario: Battery-charger and inverter output rectification in line-interactive UPS with bi-directional energy flow.

IC Role / Device Role / Timing Role: Bidirectional conduction blocker during battery discharge; withstands 160 A surge during short-circuit events.

Use Value: 175 °C Tj(max) and 160 A IFSM ensure reliability during 10 ms overload transients without thermal runaway.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IXYS MUR3060PT	600 V, 30 A, TO-247; trr = 60 ns (typ), VF = 1.15 V (typ @ 30 A/125 °C); Rth(j-c) = 1.1 °C/W.	Lower thermal resistance but TO-247 footprint differs; no DO-247 mechanical drop-in.	Preferred when board space allows TO-247 and lower thermal impedance is prioritized over isolation voltage.
Vishay VS-30E60-M3	600 V, 30 A, TO-220AC; trr = 75 ns (max), VF = 1.2 V (typ @ 30 A/125 °C); Rth(j-c) = 1.1 °C/W; VISO = 2500 VRMS.	Same isolation rating but larger TO-220AC footprint and slower trr limits usable frequency to ≤65 kHz.	Valid for cost-sensitive 50–65 kHz designs where DO-247 mounting constraints prohibit STTH30L06W.

Compared with MUR3060PT and VS-30E60-M3, STTH30L06W uniquely combines DO-247 mechanical form factor, 2500 VRMS isolation, and 65 ns trr in a single package-enabling compact, high-frequency, reinforced-isolation PFC and SMPS designs without thermal or layout compromise.

FAQ

What is the maximum allowable junction temperature for STTH30L06W?

The absolute maximum junction temperature is 175 °C, validated per ST's datasheet Table 1. Operation at this limit requires strict thermal design: heatsink interface resistance must be ≤0.5 °C/W to maintain Tj ≤ 175 °C at 30 A IF(AV) and 40 °C ambient, given Rth(j-c) = 1.7 °C/W and Rth(c-a) contribution.

Does STTH30L06W have reinforced isolation for AC-DC front-ends?

Yes. The DO-247 package provides 2500 VRMS insulation voltage, matching DOP3I-rated isolation. This meets IEC 62368-1 reinforced insulation requirements for primary-secondary barrier applications in AC-DC converters up to 300 VAC input.

How does STTH30L06W's soft recovery benefit PFC circuit EMI?

Its high softness factor (S > 1.0, per Figure 7) ensures gradual current decay during reverse recovery, reducing di/dt-induced voltage spikes and high-frequency ringing. This directly lowers common-mode noise amplitude by 10–15 dB in 30–100 MHz bands, easing EMI filter design.

Can STTH30L06W replace STTH30L06G in D2PAK-based designs?

No-STTH30L06W (DO-247) and STTH30L06G (D2PAK) differ mechanically and thermally: DO-247 has Rth(j-c) = 1.7 °C/W and through-hole mounting; D2PAK has Rth(j-c) = 1.1 °C/W and surface-mount footprint. Direct substitution requires PCB redesign and thermal revalidation.
