Product details
Overview
STTH30L06G-TR from STMicroelectronics is a 600 V, 30 A ultrafast high-voltage rectifier diode in D2PAK (TO-263) package, optimized for discontinuous-mode PFC boost stages and secondary-side rectification in industrial SMPS. It delivers 1.0 V typical forward voltage at 150 °C, 65 ns max reverse recovery time, and 1.1 °C/W junction-to-case thermal resistance.
For engineers reviewing the STTH30L06G-TR datasheet, STTH30L06G-TR pinout, STTH30L06G-TR application, or STTH30L06G-TR equivalent, key selection criteria include conduction loss modeling (P = 0.95×IF(AV) + 0.010×IF²(RMS)), soft-recovery behavior under dIF/dt up to 500 A/µs, and thermal derating above Tc = 125 °C in D2PAK mounting configurations.
Technical Context
This diode implements ST's Turbo 2 silicon technology, enabling ultrafast switching with low Qrr (typ. 1800 nC at dIF/dt = 100 A/µs, VR = 400 V) and soft reverse recovery (S factor > 1.0). Its 175 °C maximum junction temperature supports high-power density designs without forced air cooling.
Designed for hard-switched topologies, it exhibits stable trr < 90 ns across 25–150 °C and maintains IR ≤ 800 µA at 150 °C/600 V - critical for maintaining efficiency in high-temperature PFC front-ends and welder power supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - withstands peak line transients in 400 VAC industrial mains inputs without avalanche breakdown |
| IF(AV) | 30 A at Tc = 125 °C, δ = 0.5 - supports continuous 1.5 kW output in D2PAK-mounted 100 kHz flyback or boost converters |
| VF (typ) | 1.0 V at Tj = 150 °C, IF = 30 A - reduces conduction loss by ~15% vs. standard fast diodes in same package |
| trr (max) | 65 ns at Tj = 25 °C, IF = 0.5 A, dIF/dt = 50 A/µs - enables clean turn-off in 100–300 kHz SMPS with minimal EMI generation |
| Rth(j-c) | 1.1 °C/W - allows 30 W dissipation with ≤33 °C case-to-junction rise when mounted on ≥20 cm² copper area |
| IRM | 11.5–16 A peak reverse recovery current - defines snubber sizing requirements for clamp circuits in high-dI/dt applications |
| Qrr | ~1800 nC (typ.) at Tj = 125 °C, VR = 400 V - directly impacts switching loss in PFC boost diodes and must be modeled in loss budgets |
Pinout & Package
D2PAK (TO-263) surface-mount package with isolated tab (pin 1 = anode, pin 2 = cathode, tab = cathode). Requires minimum 2 mm flat zone on PCB for thermal pad soldering per Figure 13.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Input terminal for forward conduction path | Connected to switch node in boost PFC or transformer secondary in flyback; must handle 160 A surge |
| Cathode (Pin 2 + Tab) | Output terminal and primary thermal path | Tab is electrically tied to cathode and serves as main heat sink interface; requires full-solder thermal pad (≥10 cm² recommended) |
Key Features
| Feature | Design Value |
|---|---|
| Ultrafast switching (trr ≤ 65 ns) | Enables operation up to 300 kHz without excessive switching loss or EMI filter oversizing |
| Low VF (1.0 V typ. @ 150 °C) | Reduces average conduction loss by 0.45 W vs. 1.45 V diode at 30 A DC, improving 12 V/30 A rail efficiency by ~0.8% |
| Soft recovery (S factor > 1.0) | Minimizes voltage overshoot and ringing during turn-off, reducing snubber losses and RFI emissions |
| 175 °C max junction temperature | Supports operation in sealed enclosures or high-ambient environments (e.g., motor drives, UPS) without thermal throttling |
| Isolated D2PAK package (DOP3I variant available) | D2PAK version provides cost-effective surface-mount solution; DOP3I offers 2500 VRMS insulation for safety-critical AC/DC inputs |
Applications
| Industrial Switch-Mode Power Supplies | Discontinuous-Mode PFC Boost Stage |
|---|---|
Use Scenario: 3 kW telecom rectifier with 100 kHz half-bridge LLC and synchronous rectification on secondary side. IC Role / Device Role / Timing Role: Secondary-side ultrafast rectifier handling 30 A DC output; replaces slower 600 V FREDs to reduce voltage stress on MOSFETs during commutation. Use Value: 65 ns trr cuts turn-off dv/dt-induced gate drive coupling, lowering risk of false triggering in synchronous controllers. | Use Scenario: 2.2 kW server PSU front-end using boost PFC with 65 kHz switching frequency. IC Role / Device Role / Timing Role: Discontinuous-mode boost diode conducting peak currents up to 160 A during line peaks; operates at Tj ≈ 140 °C under full load. Use Value: 1.0 V VF at 150 °C reduces conduction loss by 1.35 W vs. legacy 1.35 V diode, improving PFC stage efficiency by 0.4% at 230 VAC input. |
| Welder Power Supplies | High-Temperature Motor Drive Rectification |
Use Scenario: IGBT-based inverter welder with 10 ms duty-cycle bursts and ambient up to 70 °C. IC Role / Device Role / Timing Role: Input rectifier feeding DC link capacitor; subjected to repetitive 160 A surges and high ripple current. Use Value: 175 °C Tj rating ensures reliable operation without derating, while 1.1 °C/W Rth(j-c) enables passive heatsinking even during 100% duty-cycle testing. | Use Scenario: 7.5 kW HVAC inverter with integrated DC bus rectification and forced-air-cooled heatsink. IC Role / Device Role / Timing Role: DC bus freewheeling diode clamping regenerative energy during motor deceleration; sees high dIF/dt (>300 A/µs). Use Value: Soft recovery (S > 1.0) suppresses voltage spikes > 800 V, eliminating need for TVS clamps and reducing BOM count by one component. |
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 = 1.25 V (typ) @ 150 °C; Rth(j-c) = 0.9 °C/W | Through-hole mounting only; higher VF increases conduction loss by ~0.75 W at 30 A | Select for higher thermal margin in forced-air systems where TO-247 mechanical robustness is prioritized over board space |
| Vishay V30100CI | 100 V, 30 A, D2PAK; trr = 35 ns (typ); VF = 0.82 V (typ) @ 150 °C - not voltage-compatible | Rated only for ≤100 V reverse; unsuitable for 400 VAC-derived 600 V bus applications | Reject for this voltage class; consider only for low-VR applications such as 12 V/48 V DC-DC secondaries |
Compared with MUR3060PT, STTH30L06G-TR offers superior board-level integration via D2PAK and lower VF, but trades 0.2 °C/W higher thermal resistance; versus V30100CI, it provides essential 600 V rating at the cost of slightly slower recovery - making it the only valid alternative among the three for industrial PFC use.

FAQ
What is the maximum allowable case temperature for continuous 30 A operation?
The datasheet specifies IF(AV) = 30 A at Tc = 125 °C with 50% duty cycle (δ = 0.5). Exceeding 125 °C case temperature requires linear derating: at Tc = 135 °C, maximum average current drops to 27 A. Thermal design must ensure tab solder joint remains below 125 °C under worst-case airflow and ambient conditions.
Does STTH30L06G-TR have insulated package options?
Yes - the DOP3I variant (STTH30L06PI) provides reinforced insulation rated at 2500 VRMS between cathode tab and PCB, meeting basic isolation requirements for AC/DC front-end rectifiers. The STTH30L06G-TR uses standard D2PAK with non-isolated cathode tab, requiring proper creepage/clearance layout per IEC 62368-1.
How does reverse recovery softness affect snubber design?
A softness factor S > 1.0 indicates gradual current decay during turn-off, reducing di/dt-induced voltage overshoot. This allows smaller RC snubbers - e.g., 100 Ω + 100 pF instead of 47 Ω + 220 pF - lowering power dissipation and component count in high-frequency PFC stages.
Can STTH30L06G-TR replace STTH30L06D in existing TO-220AC designs?
No - D2PAK (STTH30L06G-TR) and TO-220AC (STTH30L06D) packages are mechanically and thermally incompatible. D2PAK requires surface-mount footprint and thermal pad; TO-220AC uses through-hole leads and screw-mount heatsink. Board redesign and thermal validation are mandatory for substitution.
