Product details
Overview
FERD60M45CT from STMicroelectronics is a dual-field-effect rectifier in TO-220AB package, designed for high-frequency switching power supplies and automotive auxiliary systems. It delivers 2 × 30 A average forward current per diode, 45 V repetitive peak reverse voltage, and typ. 0.39 V forward voltage drop at 125 °C/30 A - enabling low conduction loss in DC-DC converters and alternator rectification.
For engineers reviewing the FERD60M45CT datasheet, FERD60M45CT pinout, FERD60M45CT application, or FERD60M45CT equivalent, key selection criteria include thermal coupling between dual diodes, junction-to-case thermal resistance (1.1 °C/W total), stable leakage (<50 mA at 125 °C/VRRM), and TO-220AB mechanical mounting torque (0.4–0.6 N·m).
Technical Context
This dual common-cathode rectifier uses ST's proprietary field-effect process to minimize VF/IR trade-off across temperature. Each diode operates independently with shared case thermal path, and conduction loss follows P = 0.39 × IF(AV) + 0.0067 × IF²(RMS).
Thermal design requires accounting for coupling: ΔTj(diode1) = P(diode1) × Rth(j-c) + P(diode2) × Rth(c), where Rth(c) = 0.5 °C/W couples heat between die. Junction temperature must stay ≤175 °C to avoid thermal runaway under continuous operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 45 V - maximum repetitive reverse blocking voltage per diode; defines safe operating range in buck/flyback clamp circuits |
| IF(AV) per diode | 30 A at Tc = 135 °C - continuous DC output capability per anode leg in dual-output SMPS |
| VF(typ) | 0.39 V at 30 A / 125 °C - enables <11.7 W conduction loss per diode at full rated current |
| Rth(j-c) total | 1.1 °C/W - thermal resistance from both junctions to case; critical for heatsink sizing in dual-diode layout |
| IR max | 50 mA at 125 °C / VRRM - low leakage preserves efficiency in high-temp automotive cabin environments |
| IFSM | 275 A (10 ms sine) - surge rating supports cold-crank and load-dump transient immunity |
| Tj max | 175 °C - maximum junction temperature; sets upper limit for thermal derating curves |
Pinout & Package
Package: TO-220AB, epoxy-molded, UL94 V0 compliant, with metal tab electrically connected to cathode (K). Mounting torque: 0.4–0.6 N·m.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| K (Tab) | Common Cathode | Electrically tied to both diode cathodes; serves as primary thermal and electrical return path |
| A1 | Anode 1 | Input terminal for first rectifier leg; used with K for single-phase half-wave or dual-output configuration |
| A2 | Anode 2 | Input terminal for second rectifier leg; enables independent AC input routing or interleaved conduction |
Key Features
| Feature | Design Value |
|---|---|
| Field-effect rectifier process | ST proprietary silicon technology achieving best-in-class VF/IR balance without Schottky limitations |
| Stable IR over temperature | Leakage remains <50 mA at 125 °C/VRRM - avoids thermal runaway in unregulated automotive battery systems |
| Low VF at high current/temp | 0.39 V typ. at 30 A/125 °C - reduces conduction loss by ~25% vs. standard fast recovery diodes in same package |
| High-frequency operation | Low junction capacitance (typ. 1000 pF @ 1 V) and fast recovery enable >100 kHz SMPS use without snubber penalties |
Applications
| Automotive Alternator Rectification | Server PSU Output Stage |
|---|---|
Use Scenario: Converting three-phase AC from vehicle alternator into regulated 12–14 V DC bus. IC Role / Device Role / Timing Role: Dual common-cathode rectifier replacing discrete diode pairs; handles bidirectional current sharing during phase commutation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-field-effect rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH60R04DJF | Same TO-220AB, 40 V VRRM, 0.42 V VF @ 30 A/125 °C, higher IR (120 mA @ 125 °C) | Suitable for lower-voltage 12 V systems only; less margin for 45 V transients | Prefer when cost sensitivity outweighs leakage and transient robustness requirements |
| VS-60CPH045 | TO-247AC package, 45 V VRRM, 0.44 V VF @ 30 A/125 °C, Rth(j-c) = 0.9 °C/W but no integrated dual cathode | Requires external cathode tie; better thermal performance but larger footprint and layout complexity | Choose when thermal budget is tighter than board space, and discrete cathode routing is acceptable |
Compared with STTH60R04DJF and VS-60CPH045, FERD60M45CT uniquely combines dual common-cathode integration, lowest VF at high temperature, and optimized thermal coupling - making it optimal for space-constrained, thermally demanding dual-rail SMPS designs.

FAQ
Is FERD60M45CT pin-compatible with standard TO-220AB dual diodes?
Yes - it uses the standard TO-220AB outline with A1, A2, and K (tab) terminals in identical mechanical positions. The cathode tab is internally common to both diodes, matching industry-standard dual common-cathode pinout. No PCB redesign is needed when upgrading from legacy parts like BYV26E or STTH30L06.
What is the maximum recommended heatsink thermal resistance for continuous 60 A operation?
At 60 A total (30 A per diode), power dissipation is ~23.4 W. With Rth(j-c) = 1.1 °C/W and max Tj = 175 °C, ambient must be ≤75 °C for Rth(c-a) ≤ 4.3 °C/W. For 25 °C ambient, Rth(c-a) must be ≤ 1.1 °C/W - achievable with a 30 mm × 30 mm × 20 mm aluminum heatsink and thermal interface pad.
Can FERD60M45CT be used in synchronous rectification topologies?
No - it is a passive rectifier, not a MOSFET-based synchronous device. Its field-effect structure improves VF/IR but does not support gate control. It functions as a high-performance replacement for Schottky or fast-recovery diodes in non-controlled freewheeling paths, not as a driven switch.
Does FERD60M45CT meet AEC-Q101 for automotive use?
No - while qualified for automotive environments per datasheet operating conditions (Tj up to 175 °C, tested per JESD22), it is not AEC-Q101 stress-qualified. ST offers AEC-Q101 variants (e.g., FERD60M45CTQ) for safety-critical automotive applications; this part is intended for non-safety-critical auxiliary systems.
