Product details
Overview
STTH30L06D from STMicroelectronics is a 600 V, 30 A ultrafast high-voltage rectifier diode in TO-220AC 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 175 °C maximum junction temperature.
For engineers reviewing the STTH30L06D datasheet, STTH30L06D pinout, STTH30L06D application, or STTH30L06D equivalent, key selection criteria include trr ≤ 65 ns at 25 °C, VF ≤ 1.25 V at 30 A/150 °C, Rth(j-c) = 1.1 °C/W, and VRRM = 600 V under high-dI/dt conditions up to 500 A/µs.
Technical Context
This diode employs ST's Turbo 2 silicon technology to achieve soft, ultrafast recovery with low Qrr and controlled dV/dt immunity. Its design targets high-efficiency AC-DC conversion where conduction loss (P ≈ 0.95×IF(AV) + 0.010×IF²(RMS)) and switching loss minimization are critical.
It operates with IR ≤ 800 µA at 150 °C and VR = 600 V, supports IFSM = 160 A (10 ms sine), and maintains stable trr performance across dI/dt from 50–500 A/µs - enabling reliable operation in hard-switched PFC and resonant LLC topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Withstands repetitive reverse voltage up to 600 V, suitable for 400 V DC bus applications with margin. |
| IF(AV) | 30 A at Tc = 125 °C, δ = 0.5 - Sustains average forward current of 30 A with heatsink cooling. |
| trr (max) | 65 ns at IF = 0.5 A, Irr = 0.25 A, VR = 30 V - Enables high-frequency switching (>100 kHz) with minimal turn-off loss. |
| VF (typ) | 1.0 V at IF = 30 A, Tj = 150 °C - Reduces conduction loss in high-current PFC boost diodes. |
| Rth(j-c) | 1.1 °C/W - Enables efficient thermal transfer to heatsink; allows 30 A operation at Tc ≤ 125 °C. |
| IRM (max) | 16 A at dI/dt = 100 A/µs, VR = 400 V - Limits peak reverse recovery current to reduce EMI and snubber stress. |
| Tj (max) | 175 °C - Supports operation in high-ambient industrial environments with derating. |
Pinout & Package
TO-220AC package: isolated tab (cathode), single anode lead, plastic body with UL94 V0 epoxy. Mounting torque: 0.8 Nm recommended (max 1.0 Nm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (lead) | Forward current entry | Connected to AC input or switch node; carries full load current during conduction. |
| Cathode (tab) | Forward current exit / heat path | Electrically isolated metal tab serves as cathode terminal and primary thermal interface to heatsink. |
Key Features
| Feature | Design Value |
|---|---|
| Ultrafast recovery | trr ≤ 65 ns ensures low switching loss in >100 kHz PFC and SMPS designs. |
| Low thermal resistance | Rth(j-c) = 1.1 °C/W enables compact thermal design with standard TO-220 heatsinks. |
| Soft recovery characteristic | S-factor > 1.0 at dI/dt = 100 A/µs reduces EMI generation and voltage overshoot. |
| High surge capability | IFSM = 160 A (10 ms sine) withstands inrush and transient overloads in industrial PSUs. |

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 | trr = 60 ns (typ), VF = 1.15 V (typ) at 30 A/125 °C, Rth(j-c) = 1.2 °C/W | Slightly faster trr but higher VF and thermal resistance; requires larger heatsink area. | Prefer when trr < 60 ns is mandatory and VF penalty is acceptable. |
| Vishay VS-30E60-M3 | trr = 75 ns (max), VF = 1.05 V (typ) at 30 A/125 °C, Rth(j-c) = 1.05 °C/W | Higher trr tolerance but lower VF and marginally better thermal performance. | Prefer when conduction loss dominates and 75 ns trr meets system timing budget. |
Compared with MUR3060PT and VS-30E60-M3, STTH30L06D offers the best balance of trr (65 ns max), VF (1.0 V typ), and thermal resistance (1.1 °C/W), making it optimal for space-constrained industrial PFC designs requiring both speed and efficiency.

FAQ
What is the maximum allowable case temperature for continuous 30 A operation?
The STTH30L06D supports IF(AV) = 30 A only when case temperature (Tc) is held at or below 125 °C with 50% duty cycle (δ = 0.5). Exceeding this Tc requires current derating per Figure 1 in the datasheet; at Tc = 100 °C, full 30 A is permissible with adequate heatsinking.
Does the TO-220AC package provide electrical isolation between the tab and leads?
Yes - the TO-220AC variant used in STTH30L06D features an electrically insulated tab (cathode) rated for 2500 VRMS isolation, verified per DOP3I test conditions. This eliminates need for insulating washers in most heatsink-mounting configurations.
How does reverse recovery softness (S-factor) affect EMI in PFC circuits?
A soft recovery (S > 1.0) limits di/dt during turn-off, reducing high-frequency spectral content and voltage overshoot across switching devices. At dI/dt = 100 A/µs, STTH30L06D maintains S > 1.0 (Figure 7), directly lowering conducted EMI and easing compliance with EN 55022 Class B.
Can STTH30L06D replace older STTH30L06 in existing designs?
Yes - STTH30L06D is a direct replacement for earlier STTH30L06 variants with identical TO-220AC mechanical footprint, pinout, and electrical specifications. The "D" suffix denotes updated packaging and traceability; no circuit or layout changes are required.
