Product details

Overview

STTH30L06WY from STMicroelectronics is an AEC-Q101-qualified ultrafast recovery power rectifier in DO-247 package, rated 600 V V_RRM, 30 A I_F(AV), 65 ns t_rr (max), and 1.10 V V_F (typ) at 25 °C - designed specifically for PFC boost stages in on-board chargers and EV/HEV charging infrastructure.

For engineers reviewing the STTH30L06WY datasheet, STTH30L06WY pinout, STTH30L06WY application, or STTH30L06WY equivalent, key selection criteria include junction-to-case thermal resistance (1.1 °C/W), surge capability (300 A I_FSM), high-temperature operation (–40 to +175 °C), low leakage (<25 µA at 25 °C), and automotive-grade reliability per AEC-Q101.

Technical Context

This diode employs a planar edge-terminated silicon structure optimized for ultrafast soft recovery, minimizing switching losses and EMI in high-frequency PFC converters. Its dynamic parameters-including 11.5–16 A I_RM, 500 ns t_fr, and 2.5 V V_FP-are characterized under controlled dI_F/dt (100 A/µs) and T_j = 125 °C conditions.

The device supports dual-package deployment: DO-247 (4.36 g, tube, 30 pcs) for high-power bolt-down mounting with 0.8 N·m torque spec, and D²PAK (1.48 g, tape-and-reel) for surface-mount assembly - both ECOPACK2-compliant and rated for continuous operation up to 175 °C junction temperature.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	600 V - guarantees reverse blocking across full automotive temperature range (–40 to +175 °C)
I_F(AV)	30 A - average forward current at T_c = 125 °C with 50% duty cycle square wave
t_rr (max)	65 ns - ultrafast recovery time measured at I_F = 0.5 A, I_R = 1 A, I_RR = 0.25 A
V_F (typ)	1.10 V - forward voltage drop at I_F = 30 A and T_j = 25 °C, enabling low conduction loss
R_th(j-c)	1.1 °C/W - thermal resistance from junction to case, critical for heatsink sizing in OBC designs
I_FSM	300 A - non-repetitive surge current rating (10 ms sinusoidal), supporting inrush and fault tolerance
I_R (max)	800 µA - maximum reverse leakage at T_j = 150 °C and V_R = V_RRM, ensuring stability in high-temp PFC

Pinout & Package

STTH30L06WY is housed in a DO-247 through-hole package with two terminals: anode and cathode. The package features a metal tab for direct heatsink mounting, UL94 V0 epoxy molding, and mechanical dimensions compliant with ST's drawing (A = 4.85–5.15 mm, H = 15.45–15.75 mm, L = 19.85–20.15 mm).

Pin/Terminal	Circuit Role	Design Meaning
Anode	Forward current entry point	Connected to AC input or switch node in boost PFC; must withstand peak reverse voltage during off-state
Cathode	Forward current exit / output node	Connects to DC bus capacitor; carries continuous 30 A average current and handles 300 A surge transients
Metal tab	Thermal and electrical connection to cathode	Electrically tied to cathode; provides low-impedance thermal path to heatsink (R_th(j-c) = 1.1 °C/W)

Key Features

Feature	Design Value
AEC-Q101 qualification	Validated for automotive power electronics including OBC and charging stations, covering stress tests across –40 to +175 °C
Ultrafast soft recovery	t_rr ≤ 65 ns with S-factor > 0.8 at 125 °C, reducing EMI and voltage overshoot in hard-switched PFC
Low conduction loss	V_F = 1.10 V (typ) at 30 A/25 °C enables <15 W conduction loss in 3.3 kW PFC stage
High surge robustness	300 A I_FSM (10 ms) supports repeated line surges and startup inductance energy dump
High-temperature operation	Rated for continuous 175 °C junction temperature, enabling compact thermal design without derating in confined OBC enclosures

Applications

IC Role / Device Role / Timing Role: Ultrafast power rectifier in boost diode position, conducting during MOSFET off-time and recovering before next switching cycle.

Use Value: 65 ns t_rr and soft recovery minimize reverse recovery loss and snubber requirements, improving system efficiency by ≥0.4% at full load.

Use Scenario: 150 kW DC fast charger using multi-phase SiC-based PFC followed by LLC isolation and synchronous rectification.

IC Role / Device Role / Timing Role: Secondary-side output rectifier handling 30 A DC output current at 400–1000 V bus, operating continuously at elevated ambient temperatures.

Use Value: 175 °C T_j(max) and 800 µA I_R at 150 °C ensure stable regulation and low standby loss over lifetime in outdoor-rated enclosures.

Industrial PFC Module for EVSE

Automotive Auxiliary Power Supply

Use Scenario: DIN-rail mounted 3.3 kW single-phase PFC module used in Level 2 EVSE with active cooling.

IC Role / Device Role / Timing Role: Main rectifier in boost converter, selected for low V_F and high I_FSM to handle grid transients and unbalanced loads.

Equivalent & Alternatives

The following parts are listed as comparable options for similar ultrafast 600 V power rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH30L06GY	D²PAK package (vs. DO-247); identical electrical specs; R_th(j-c) = 1.1 °C/W; 1.48 g weight	Suitable for automated SMT assembly; requires PCB copper area for thermal management instead of bolt-on heatsink	Select when board space allows SMT integration and thermal interface uses soldered copper pour rather than mechanical clamping.
IXYS MUR3060CT	TO-247AC package; 600 V/30 A; t_rr = 75 ns (max); V_F = 1.25 V (typ); not AEC-Q101 qualified	Lacks automotive qualification; higher V_F increases conduction loss; same surge rating (300 A)	Acceptable for industrial PFC where AEC-Q101 is not mandated; verify thermal layout due to different R_th(j-c) (1.3 °C/W).

Compared with STTH30L06GY and IXYS MUR3060CT, STTH30L06WY uniquely combines DO-247 mechanical robustness, AEC-Q101 compliance, and lowest V_F among 600 V/30 A ultrafast diodes - making it optimal for bolt-mounted, high-reliability automotive PFC where thermal cycling and vibration endurance are critical.

FAQ

What is the maximum recommended torque for mounting STTH30L06WY in DO-247 package?

The DO-247 package specifies a recommended torque value of 0.8 N·m and a maximum torque of 1.0 N·m for the mounting screw. Exceeding 1.0 N·m risks damaging the internal bond wires or deforming the metal tab, compromising thermal performance and long-term reliability under thermal cycling.

Does STTH30L06WY require a heatsink in a 30 A continuous application?

Yes - at 30 A I_F(AV), junction temperature rise is ~33 °C above case temperature (P ≈ 33 W × 1.1 °C/W). Without a heatsink, case temperature would exceed safe limits. A heatsink maintaining T_c ≤ 125 °C is mandatory to stay within the 175 °C T_j(max) rating.

How does STTH30L06WY's soft recovery reduce EMI in PFC circuits?

Its soft recovery (S-factor > 0.8 at 125 °C) limits the rate of change of reverse current (di/dt) during turn-off, suppressing high-frequency ringing and voltage spikes across parasitic inductances. This directly lowers conducted EMI in the 150 kHz–30 MHz band, easing EMC filter design in automotive OBCs.

Is STTH30L06WY pin-compatible with other DO-247 rectifiers like STTH30L06GY?

No - STTH30L06GY uses D²PAK (surface-mount), while STTH30L06WY uses DO-247 (through-hole with screw mount). They share identical electrical characteristics but differ mechanically: DO-247 has a metal tab for bolt-down heatsinking; D²PAK relies on PCB copper for thermal transfer. Footprint and assembly processes are not interchangeable.
