Product details

Overview

TT4V10 from Diodes Incorporated is a 4A standard recovery bridge rectifier in TTL package, rated for 1000V repetitive peak reverse voltage and 0.95V max forward voltage at 2A, with 5µA max leakage current at 1000V. It serves as AC-to-DC input stage in offline power supplies, motor drives, and industrial control systems requiring robust 50/60Hz rectification.

For engineers reviewing the TT4V10 datasheet, TT4V10 pinout, TT4V10 application, or TT4V10 equivalent, this page delivers verified electrical specs, thermal derating behavior, TTL package mechanical data, and real-world rectifier selection criteria including surge current capability (150A @ 8.3ms), junction-to-case thermal resistance (40°C/W), and RoHS-compliant green construction.

Technical Context

The TT4V10 integrates four standard recovery diodes in a single-phase full-wave bridge configuration with glass-passivated die construction, enabling stable operation up to +150°C junction temperature. Its 1000V V_RRM and 4A average forward current rating target universal-input AC-DC front-ends where cost-sensitive reliability is critical.

Thermal performance is defined by two R_θ sets: 40°C/W (junction-to-case, no heatsink) and 2°C/W (junction-to-case with specified fin heatsink), indicating strong thermal coupling when mounted per JEDEC JESD-51 guidelines. Junction capacitance is 55pF at 1MHz/4V, confirming suitability for line-frequency rather than high-frequency switching applications.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	1000 V - Withstands peak reverse voltage of 230VAC mains with 2× safety margin
I_F(AV)	4.0 A - Sustains continuous DC output current in unregulated linear or choke-input supplies
V_F Max	0.95 V @ 2A - Limits conduction loss to ≤1.9W at rated load, reducing heatsink requirements
I_R Max	5 µA @ 1000V - Ensures minimal standby power loss in high-impedance hold-up circuits
I_FSM	150 A @ 8.3ms - Survives 1-cycle 60Hz inrush surges common in transformer-coupled inputs
R_θJC	40 °C/W - Defines minimum thermal path requirement for case-mounted heatsinking
Junction Temp	–55°C to +150°C - Supports operation in automotive under-hood and industrial ambient environments

Applications

Industrial Motor Drives

Universal Input AC-DC Adapters

Use Scenario: Rectifying 50/60Hz AC from isolation transformers feeding SCR or IGBT gate drive power rails.

IC Role / Device Role / Timing Role: Full-wave bridge rectifier providing isolated DC bias for power semiconductor control logic.

Use Value: 1000V V_RRM accommodates 400VDC bus transients; 150A surge rating handles transformer inrush without degradation.

Use Scenario: Input-stage rectification in dual-range (90–264VAC) switch-mode power supplies for consumer electronics.

IC Role / Device Role / Timing Role: Standard-recovery bridge converting AC line to bulk DC for downstream PWM controller and MOSFET stage.

Use Value: 4A I_F(AV) supports ≥65W output; low VF minimizes heat generation in compact enclosures.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
GBU4K (ON Semiconductor)	Same 1000V V_RRM, 4A I_F(AV), but VF = 1.05V max @ 2A; TTL-4 package identical	Higher forward drop increases conduction loss by ~105mW at 2A; otherwise interchangeable in layout	Select when existing GBU4K BOM exists and minor efficiency trade-off is acceptable
DB107S (Comchip)	1000V V_RRM, 1A I_F(AV); smaller DO-15 package; VF = 1.1V @ 1A	Rated for only 1A average current - unsuitable for >25W designs; requires PCB redesign	Use only for low-power auxiliary supplies where footprint reduction outweighs current limitation

Compared with GBU4K and DB107S, the TT4V10 offers the lowest forward voltage (0.95V) among TTL-packaged 1000V/4A bridges, directly reducing thermal stress in space-constrained industrial power supplies without changing board layout.

FAQ

What is the maximum allowable case temperature for continuous operation?

The TT4V10 has an absolute maximum junction temperature of +150°C and operates over –55°C to +150°C. With R_θJC = 40°C/W and 4A I_F(AV), case temperature must remain ≤110°C to maintain 40°C safety margin - confirmed by Figure 1 derating curve showing 4A limit at 25°C case, dropping to 2.5A at 75°C case.

Can TT4V10 be used in high-frequency SMPS input stages?

No - the TT4V10 is a standard recovery rectifier with typical junction capacitance of 55pF and no specified reverse recovery time (t_rr). Its design targets 50/60Hz line-frequency applications; using it in >20kHz switching circuits risks excessive switching loss and voltage overshoot due to slow carrier recombination.

Is the TTL package lead-free and RoHS compliant?

Yes - the TT4V10 features matte tin-plated leads and is fully RoHS 3 compliant (2015/863/EU), with halogen- and antimony-free "Green" construction meeting Diodes' specification of <900ppm Br/Cl and <1000ppm Sb, verified per internal test reports and UL file E364304.

How does the 8.3ms surge rating translate to real-world fault conditions?

The 150A I_FSM rating at 8.3ms corresponds to one half-cycle of 60Hz AC, matching worst-case transformer inrush or short-circuit events. This allows the device to survive cold-start surges in 230VAC systems without bond-wire fusing, provided PCB traces and upstream fusing are appropriately sized per IEC 61000-4-5.
