Product details
Overview
MC7806BD2TR4G from onsemi is a fixed-output +6.0 V, 1.0 A linear voltage regulator in D2PAK-3 surface-mount package, featuring internal thermal shutdown, short-circuit current limiting, safe-area compensation, and ±2% output voltage tolerance at 25°C. It delivers stable local regulation for industrial control modules, automotive body electronics, and embedded power supplies where input ripple rejection and robust fault protection are required.
For engineers reviewing the MC7806BD2TR4G datasheet, pinout, applications, or equivalent options, this page provides verified electrical specs, thermal performance data, PCB layout guidance for heatsinking, and validated alternative parts for design flexibility and supply continuity.
Technical Context
The MC7806BD2TR4G implements a monolithic NPN pass transistor architecture with integrated bandgap reference, error amplifier, and protection circuitry. Its dropout voltage remains fixed at 2.0 V (at 1.0 A, 25°C), enabling operation with input as low as 8.0 V while maintaining regulated 6.0 V output.
Thermal management is critical: junction-to-case thermal resistance is 5.0°C/W, and the D2PAK-3 package requires external heatsinking to sustain 1.0 A continuous output. Ripple rejection reaches 62 dB at 120 Hz (11.5–18 VIN), confirming suitability for noisy DC bus environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | +6.0 V nominal, ±2% tolerance at 25°C - ensures compatibility with 6 V logic and analog subsystems without post-regulation trimming. |
| Output Current | 1.0 A continuous - supports mid-power microcontrollers, sensors, and interface ICs without external current boosting. |
| Dropout Voltage | 2.0 V at 1.0 A and 25°C - mandates minimum 8.0 V input under full load; dictates upstream supply headroom design. |
| Ripple Rejection | 62 dB at 120 Hz - suppresses AC line-derived ripple from unregulated DC inputs, reducing need for large bulk capacitance. |
| Quiescent Current | 3.3 mA typical - enables low standby power in always-on systems; increases ≤0.8 mA over full input range. |
| Thermal Shutdown | Activates at +150°C junction temperature - protects against sustained overload or inadequate heatsinking in enclosed enclosures. |
| Short-Circuit Limit | 0.2 A typical - limits fault current during output shorts, preventing trace damage and enabling safe auto-recovery. |
Pinout & Package
D2PAK-3 (Case 936) surface-mount package with exposed metal tab thermally and electrically connected to Pin 2 (Ground). Requires solder pad thermal relief and copper pour for heatsinking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input | Unregulated DC input (8.0–35 V); must be bypassed with ≥0.33 µF capacitor near pin for stability. |
| 2 | Ground | Common reference for input, output, and heatsink; connects directly to exposed tab - critical for thermal path and noise coupling control. |
| 3 | Output | Regulated +6.0 V output; no mandatory output capacitor, but ≥0.1 µF improves transient response and prevents instability. |
Key Features
| Feature | Design Value |
|---|---|
| No external components required | Operates as standalone regulator with only input/output capacitors - reduces BOM count and layout complexity. |
| Internal safe-area compensation | Reduces short-circuit current as VIN–VOUT increases - prevents secondary failure during high-differential-voltage faults. |
| 1.5% to 4% output tolerance options | MC7806BD2TR4G uses 2% grade - balances cost and precision for non-critical analog/IO rails. |
| Pb-free and RoHS-compliant | Meets environmental compliance requirements for industrial and automotive end equipment without lead-free process penalties. |
| AEC-Q100 stress-tested variants available | NCV7806BD2TR4G variant qualified for automotive - confirms reliability under temperature cycling, humidity, and vibration stress. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-output linear regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM7806CD2T | Same 6 V output, 1.0 A rating, TO-263 (D2PAK) package; ±2% tolerance; higher quiescent current (4.5–7.5 mA). | Lacks AEC-Q100 qualification; not recommended for automotive-grade designs requiring PPAP documentation. | Select when cost sensitivity outweighs automotive qualification needs and higher IQ is acceptable. |
| NCV7806BD2TR4G | Identical pinout, package, and electrical specs; AEC-Q100 qualified, PPAP-capable, and rated for −40°C to +125°C operation. | Designed specifically for automotive body electronics with enhanced ESD (2000 V HBM) and extended temperature validation. | Choose for automotive OEM or Tier-1 programs requiring certified component traceability and stress test evidence. |
Compared with LM7806CD2T and NCV7806BD2TR4G, the MC7806BD2TR4G offers identical core regulation performance but lacks automotive qualification - making it optimal for industrial and commercial applications where cost and availability are prioritized over automotive compliance documentation.

FAQ
What is the maximum input voltage for MC7806BD2TR4G?
The absolute maximum input voltage for MC7806BD2TR4G is 35 V DC, as specified in the Absolute Maximum Ratings table. Operation above this voltage risks permanent device damage due to junction breakdown. For reliable 1.0 A output, input should remain within 8.0–25 V to maintain adequate headroom and thermal margin.
Does MC7806BD2TR4G require an input capacitor?
Yes - MC7806BD2TR4G requires a minimum 0.33 µF input bypass capacitor placed directly across Pins 1 and 2. This capacitor stabilizes the regulator under dynamic load changes and suppresses high-frequency noise from upstream sources. Tantalum or ceramic types with low ESR are preferred.
Can MC7806BD2TR4G be used in automotive applications?
MC7806BD2TR4G itself is not AEC-Q100 qualified. For automotive use, select the NCV7806BD2TR4G variant - which shares identical pinout and electrical specs but includes full automotive stress testing, PPAP documentation, and extended temperature validation (−40°C to +125°C).
What is the thermal resistance of MC7806BD2TR4G?
MC7806BD2TR4G has a junction-to-case thermal resistance (RθJC) of 5.0°C/W and junction-to-ambient resistance (RθJA) of 65°C/W (with standard PCB copper pour). To sustain 1.0 A continuously, heatsinking must keep junction temperature below +150°C - typically requiring ≥2 in² of 2-oz copper connected to the exposed tab.
How does MC7806BD2TR4G handle short-circuit conditions?
MC7806BD2TR4G features internal short-circuit current limiting that caps output current at approximately 0.2 A during sustained output shorts. Combined with thermal shutdown at +150°C, this dual-protection scheme prevents destructive failure and allows safe auto-recovery once the fault is removed.
