Product details

Overview

STTH30L06GY-TR from STMicroelectronics is an AEC-Q101-qualified ultrafast recovery power rectifier in D²PAK 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 - engineered for PFC boost stages in on-board chargers and EV/HEV charging stations.

For engineers reviewing the STTH30L06GY-TR datasheet, STTH30L06GY-TR pinout, STTH30L06GY-TR application, or STTH30L06GY-TR equivalent, key selection criteria include ultrafast soft recovery (S factor > 0.8), high T_j capability (–40 to +175 °C), low conduction loss (P = 0.95 × I_F(AV) + 0.010 × I_F(RMS)²), and AEC-Q101 qualification for automotive-grade reliability.

Technical Context

This diode employs a platinum-doped silicon process to achieve ultrafast, soft reverse recovery with t_rr ≤ 65 ns and I_RM ≤ 16 A under 100 A/µs dI_F/dt - critical for minimizing switching losses and EMI in continuous-conduction-mode (CCM) PFC circuits. Its low Q_RR (< 3 µC typical at 125 °C) and high surge rating (I_FSM = 300 A, 10 ms) support robust operation during line transients.

The device features dual thermal paths: R_th(j–c) = 1.1 °C/W (D²PAK) enables direct heatsink mounting, while junction temperature remains stable up to +175 °C - validated across –40 to +175 °C V_RRM guarantee and low leakage (≤ 800 µA at 150 °C).

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	600 V - supports 400 V AC input PFC designs with ≥1.5× safety margin against line surges
I_F(AV)	30 A - delivers sustained output rectification in 3.3–22 kW OBC systems at T_c = 125 °C
t_rr (max)	65 ns - enables high-frequency (>100 kHz) PFC operation with minimal turn-off loss and voltage overshoot
V_F (typ)	1.10 V @ 25 °C - reduces conduction loss to ~33 W at 30 A average current (δ = 0.5 square wave)
R_th(j–c)	1.1 °C/W - allows 50 W dissipation with ≤55 K rise above case temperature when mounted to heatsink
I_FSM	300 A (10 ms sine) - withstands inrush and fault currents in uncontrolled rectifier front-ends
T_j (max)	+175 °C - ensures functional stability in engine-bay-mounted OBC modules without derating

Pinout & Package

STTH30L06GY-TR uses the D²PAK (TO-263) surface-mount package: 3-terminal, single-diode configuration with cathode (pin 1), anode (pin 2), and exposed thermal pad (pin 3, electrically connected to cathode). The package supports high-current PCB routing and direct heatsink attachment via the thermal pad.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Tab)	Cathode	Primary current return path; thermally coupled to heatsink via soldered copper area
Pin 2	Anode	Input terminal for forward conduction; routed with low-inductance trace in PFC boost leg
Pin 3 (Exposed Pad)	Cathode (internally tied)	Provides dominant thermal path (R_th(j–c) = 1.1 °C/W); must be soldered to ≥25 cm² copper pour

Key Features

Feature	Design Value
AEC-Q101 qualification	Validated for automotive powertrain and charging systems per stress test requirements (HTOL, TC, HAST, UHAST)
Ultrafast soft recovery	t_rr ≤ 65 ns with S factor > 0.8 - suppresses voltage ringing and reduces snubber losses in hard-switched PFC
Low conduction loss	V_F = 1.10 V (typ) @ 25 °C - enables >98% efficiency in 11 kW PFC stage at full load
High surge capability	I_FSM = 300 A (10 ms) - survives repeated cold-start surges in 3-phase OBC front-ends
Extended temperature range	V_RRM guaranteed from –40 to +175 °C - eliminates need for voltage derating in under-hood environments

Applications

Use Scenario: Secondary-side rectification in modular 150–350 kW liquid-cooled DC fast chargers.

IC Role / Device Role / Timing Role: High-current freewheeling diode in interleaved LLC resonant converters feeding 800 V battery stacks.

Use Value: 175 °C max junction temperature and 300 A surge rating ensure uninterrupted operation during grid-voltage dips and thermal cycling.

Industrial PFC Module

Use Scenario: Three-phase active PFC in 15 kW industrial UPS and motor drives.

IC Role / Device Role / Timing Role: Output rectifier in Vienna rectifier topology, operating at 100 kHz with 30 A phase current.

Use Value: Low Q_RR (< 3 µC) and 1.10 V V_F reduce total power loss to < 45 W per diode, enabling natural convection cooling.

Use Scenario: Grid-tied solar inverter with two-stage conversion (boost + inverter) for commercial PV farms.

IC Role / Device Role / Timing Role: DC-link clamp diode in boost stage, clamping transient overvoltage during islanding detection events.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH30L06WY	Same die, DO-247 through-hole package; R_th(j–c) = 0.9 °C/W; higher I_FSM (350 A)	Better suited for prototyping, high-reliability industrial supplies, and manual assembly	Select when board-level thermal management favors bolt-down heatsinking or when tape-and-reel is not required
IXYS MUR3060CT	600 V, 30 A dual common-cathode; t_rr = 75 ns (max); V_F = 1.75 V (typ); no AEC-Q101 qualification	Acceptable for non-automotive PFC but lacks soft recovery and automotive temp range guarantee	Choose only for cost-sensitive industrial designs where AEC-Q101 and soft recovery are not mandatory

Compared with STTH30L06WY, the STTH30L06GY-TR offers superior manufacturability in automated SMT lines and tighter thermal control via D²PAK's defined thermal pad layout; versus MUR3060CT, it delivers lower conduction loss, softer recovery, and certified automotive reliability - critical for OBC lifetime validation.

FAQ

What is the maximum allowable case temperature for continuous operation?

The STTH30L06GY-TR supports continuous operation with case temperature (T_c) up to 125 °C, as specified for its 30 A I_F(AV) rating. At higher T_c, derating applies per Figure 1 in DS7255; operation beyond 125 °C requires thermal modeling using R_th(j–c) = 1.1 °C/W and verified junction temperature monitoring.

Is the D²PAK thermal pad electrically isolated?

No - the exposed thermal pad (Pin 3) is internally connected to the cathode (Pin 1). It must be soldered to a cathode-referenced copper pour on the PCB. Electrical isolation is not possible without external insulation layers, which would severely degrade thermal performance.

Does this diode require a snubber circuit in PFC applications?

A snubber is not mandatory due to its soft recovery (S factor > 0.8) and low Q_RR, but a small RC snubber (e.g., 100 Ω + 100 pF) is recommended across anode–cathode in high-dI/dt (>150 A/µs) CCM PFC designs to further damp residual ringing and protect MOSFETs from voltage overshoot.

How does the DO-247 variant (STTH30L06WY) differ electrically from STTH30L06GY-TR?

Electrically identical - both share the same silicon die, V_RRM, I_F(AV), t_rr, V_F, and thermal characteristics. The only differences are mechanical: DO-247 has lower R_th(j–c) (0.9 °C/W), higher I_FSM (350 A), and through-hole mounting; D²PAK offers SMT compatibility and tighter assembly control.
