STMicroelectronics STTH16L06CGY-TR

Overview

STTH16L06CGY-TR from STMicroelectronics is an AEC-Q101-qualified ultrafast high-voltage dual common-cathode rectifier diode in D²PAK package, rated for 600 V repetitive peak reverse voltage, 16 A average forward current (per device), and 35 ns maximum reverse recovery time. It serves as a discontinuous-mode PFC boost diode and output rectifier in automotive switching power supplies.

For engineers reviewing the STTH16L06CGY-TR datasheet, STTH16L06CGY-TR pinout, STTH16L06CGY-TR application, or STTH16L06CGY-TR equivalent, key selection criteria include ultrafast trr performance, low VF at 150 °C (1.05 V typ.), thermal resistance (Rth(j–c) = 1.6 °C/W total), AEC-Q101 qualification, and D²PAK surface-mount compatibility for high-power density automotive designs.

Technical Context

This dual-diode rectifier integrates two independent ultrafast silicon junctions sharing a common cathode terminal, enabling synchronous operation in bridge or dual-phase PFC topologies. Its design targets minimized reverse recovery charge (Qrr) and soft recovery behavior-critical for reducing EMI and switching losses in 100–500 kHz automotive SMPS.

The device operates across –40 °C to +175 °C junction temperature range with low thermal resistance (1.6 °C/W total junction-to-case) and supports PPAP-compliant production. Dynamic parameters-including trr = 35 ns (max), IRM = 4.5–6.5 A, and tfr = 200 ns-are characterized under standardized dIF/dt conditions (up to 100 A/µs) and elevated temperature (125 °C).

Key Specifications

Pinout & Package

FAQ

What is the maximum allowable case temperature for continuous operation?

The STTH16L06CGY-TR supports continuous operation with case temperature (TC) up to 130 °C for 10 A per diode (20 A per device), as specified in Table 2. At TC = 135 °C, the rated average forward current is 16 A per device. Derating curves in Figure 1 confirm stable conduction loss up to TC = 140 °C under pulse conditions.

Is the D²PAK tab electrically isolated or connected to a terminal?

The exposed metal tab in the D²PAK package is electrically connected to the common cathode (K) terminal and must be treated as a live circuit node. It is not isolated; PCB layout must maintain clearance to adjacent traces and planes per 600 V working voltage requirements.

How does the dual-diode configuration affect thermal coupling between channels?

Thermal coupling between diodes is modeled via Rth(c) = 0.7 °C/W (Table 3). When both diodes conduct simultaneously, junction temperature rise of Diode 1 equals P₁ × 2.5 °C/W + P₂ × 0.7 °C/W, confirming asymmetric thermal interaction that must be accounted for in multi-phase PFC thermal simulation.

Can STTH16L06CGY-TR replace STTH16L06CTY in a TO-220AB design?

No-STTH16L06CGY-TR uses D²PAK (surface-mount) packaging with different footprint, thermal pad layout, and mechanical mounting. While electrically identical, the package change requires PCB redesign, requalification of thermal performance, and updated assembly processes (reflow vs. through-hole).
