Product details

Overview

PDU620-13 from Diodes Incorporated is an ultra-fast recovery rectifier diode in PowerDI5 package, rated for 200 V peak repetitive reverse voltage, 6 A average forward current, and 25 ns reverse recovery time; used in low-voltage, high-frequency inverters, freewheeling paths, and polarity protection circuits.

For engineers reviewing the PDU620-13 datasheet, PDU620-13 pinout, PDU620-13 application, or PDU620-13 equivalent, key selection criteria include reverse recovery time, thermal resistance (R_JS = 1.5 °C/W), forward voltage at 6 A/150 °C (0.860 V), junction temperature range (–65 to +175 °C), and AEC-Q101 qualification for automotive reliability.

Technical Context

This device employs glass-passivated die construction to achieve ultra-fast switching with trr = 25 ns under IF = 0.5 A, IR = 1.0 A, IRR = 0.25 A test conditions. Its 200 V V_RRM and 6 A I_O rating target medium-power DC/DC and AC/DC secondary-side rectification where efficiency and thermal management are critical.

The PowerDI5 package provides low thermal resistance to soldering point (R_JS = 1.5 °C/W) and supports high surge capability (I_FSM = 150 A, 8.3 ms half-sine). It is qualified to AEC-Q101 and uses lead-free, RoHS-compliant "green" molding compound with UL 94V-0 flammability rating.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	200 V - Maximum repetitive reverse blocking voltage; defines safe operating limit in bridge or freewheeling configurations.
I_O	6 A - Average rectified output current at TA = 25 °C; derated per PCB layout (FR-4: R_JA = 95 °C/W; Polyimide w/ large cathode pad: R_JA = 40 °C/W).
t_rr	25 ns - Measured reverse recovery time; enables high-frequency operation (>100 kHz) with minimal switching loss.
V_FM	0.860 V @ 6 A, 150 °C - Forward voltage drop at elevated junction temperature; directly impacts conduction loss and thermal design margin.
R_JS	1.5 °C/W - Junction-to-soldering-point thermal resistance; enables direct thermal coupling to copper pour for high-power density layouts.
T_j Range	–65 to +175 °C - Extended junction temperature range supports under-hood automotive and industrial environments without derating.

Pinout & Package

PowerDI5 surface-mount package with two terminals: anode and cathode. Cathode marked by band on top surface; bottom-side exposed copper pad serves as thermal and electrical cathode connection. Pins must be electrically connected to common copper pour on PCB for thermal performance.

Pin/Terminal	Circuit Role	Design Meaning
Anode (Top Left)	Forward current entry	Connected to input/source side of rectifier; small pad (2.7 mm × 1.6 mm) minimizes parasitic inductance.
Cathode (Top Right + Bottom Pad)	Forward current exit / Heat sink node	Top-right terminal and large bottom copper area (9.4 mm × 7.2 mm) jointly conduct current and dissipate heat; requires full-solder coverage.

Key Features

Feature	Design Value
Glass-passivated die	Enables stable reverse characteristics and long-term reliability under high dv/dt and humidity stress.
AEC-Q101 qualification	Validated for automotive-grade applications including engine control modules and body electronics.
Ultra-low R_JS (1.5 °C/W)	Allows >5 W continuous dissipation with minimal board-area thermal solution-no external heatsink required.
Lead-free & halogen-free	Complies with RoHS Directive Annex exemptions and JEDEC MSL Level 1; suitable for reflow assembly without moisture sensitivity concerns.

Applications

Automotive Engine Control Unit (ECU)

Industrial DC/DC Converter Secondary Side

Use Scenario: Freewheeling diode across solenoid drivers and fuel injector coils in 12 V/24 V ECU power stages.

IC Role / Device Role / Timing Role: Fast-recovery freewheeling diode suppressing inductive kickback during MOSFET turn-off.

Use Value: 25 ns t_rr limits voltage overshoot to <10% above supply rail, reducing snubber losses and EMI generation.

Use Scenario: Output rectifier in isolated 48 V to 12 V flyback converter for PLC I/O modules.

IC Role / Device Role / Timing Role: Synchronous rectification alternative where cost-sensitive designs avoid gate-drive complexity.

Use Value: 0.860 V V_FM at 150 °C enables >92% efficiency at full load while maintaining T_j < 140 °C on 2 oz. FR-4.

USB-C PD Adapter Polarity Protection

Photovoltaic Microinverter DC Link

Use Scenario: Reverse-polarity protection diode at USB-C PD input stage before buck controller.

IC Role / Device Role / Timing Role: Unidirectional blocking element preventing damage from miswired adapters.

Use Value: 200 V V_RRM accommodates transient surges up to ±150 V; 6 A rating supports 65 W adapter designs.

Use Scenario: Bypass diode across PV cell strings in microinverters to prevent hot-spot heating.

IC Role / Device Role / Timing Role: String-level bypass path during partial shading or cell failure.

Use Value: –65 to +175 °C T_j range ensures reliable operation under desert ambient extremes (T_A up to 85 °C).

Equivalent & Alternatives

The following parts are listed as comparable options for similar ultra-fast rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH6L06S	TO-277 package; 600 V V_RRM; 20 ns t_rr; higher V_F (1.15 V @ 6 A)	Higher voltage rating suits 400 V bus systems; less optimal for 200 V-class designs due to excess voltage margin and larger footprint.	Select when 600 V blocking is required and TO-277 mounting is preferred over PowerDI5's low-profile SMT fit.
MBR620CT	TO-220AB package; dual Schottky; 20 V V_R; 0.62 V V_F @ 6 A; no reverse recovery	Lower voltage, lower loss, but unsuitable for 200 V reverse blocking; limited to <30 V applications.	Choose only for low-voltage (<30 V) synchronous rectification where zero t_rr is mandatory and reverse voltage is ≤20 V.

Compared with STTH6L06S and MBR620CT, PDU620-13 uniquely balances 200 V blocking, 25 ns speed, and PowerDI5 thermal performance-making it optimal for space-constrained, thermally demanding 12–48 V automotive and industrial rectification where TO-220 or TO-277 packages are prohibitive.

FAQ

What is the maximum allowable junction temperature for continuous operation?

The PDU620-13 has a specified operating junction temperature range of –65 °C to +175 °C. For continuous operation, the absolute maximum steady-state T_j is +175 °C. Derating curves in Figure 4 confirm 6 A I_O is valid up to +125 °C ambient on FR-4, assuming proper thermal pad layout per AP02001.

Is the PowerDI5 package compatible with standard reflow soldering profiles?

Yes-the PDU620-13 uses matte tin–annealed terminals and is qualified for lead-free reflow per J-STD-020C. Its MSL Level 1 rating means it can be stored indefinitely at ≤30 °C/60% RH without baking. Standard IPC/JEDEC J-STD-020D profile with peak temperature ≤260 °C is fully supported.

Does the device require a heatsink for 6 A DC operation?

No external heatsink is required. With the recommended cathode pad layout (9.4 mm × 7.2 mm on polyimide PCB), R_JA drops to 40 °C/W, enabling 6 A DC operation at T_A = 75 °C while holding T_j < 155 °C. On FR-4, use thermal vias under the cathode pad to maintain R_JA ≤ 60 °C/W.

How does the 25 ns reverse recovery time impact EMI in high-frequency converters?

A 25 ns t_rr reduces high-frequency ringing amplitude and duration during diode turn-off, lowering broadband EMI emissions by 6–10 dB compared to standard recovery diodes. This allows simpler filtering and helps meet CISPR-25 Class 5 requirements in automotive power supplies without added snubbers.
