Product details
Overview
MC7806BD2TR4 from onsemi is a fixed-output +6.0 V, 1.0 A linear voltage regulator in D2PAK-3 (TO-263) package with internal thermal shutdown, short-circuit current limiting, and safe-area compensation. It delivers stable output under input voltages from 8.5 V to 35 V, supports ≥1.0 A continuous load with adequate heatsinking, and is used for local regulation in industrial power supplies and embedded control modules.
For engineers reviewing the MC7806BD2TR4 datasheet, pinout, applications, or equivalent options, key selection criteria include guaranteed ±2% output tolerance at 25°C, 2.0 V dropout at 1.0 A, 68 dB ripple rejection at 120 Hz, and compatibility with standard 0.33 µF input / optional 0.1 µF+ output capacitors for transient stability.
Technical Context
The MC7806BD2TR4 implements a monolithic series-pass transistor architecture with built-in current-limiting circuitry that reduces short-circuit current as pass-device voltage increases, preventing thermal runaway. Its safe-area compensation dynamically adjusts current limit versus VCE, enabling robust operation across wide input-output differentials.
Thermal overload protection activates at +150°C junction temperature, forcing shutdown until cooldown; recovery is automatic. Quiescent current remains stable at 3.2–6.0 mA across 7.5–25 V input and 5–1500 mA load, ensuring predictable bias consumption in low-power standby modes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | +6.0 V nominal, ±2% tolerance at TJ = 25°C - ensures precise rail generation for 5 V-tolerant logic and analog circuits |
| Output Current | ≥1.0 A continuous (with heatsink), 2.2 A peak - supports motor drivers, solenoid interfaces, and multi-rail subsystems |
| Dropout Voltage | 2.0 V at IO = 1.0 A, TJ = 25°C - requires minimum 8.5 V input for regulated 6 V output under full load |
| Ripple Rejection | 68 dB at f = 120 Hz, VIN = 11 V - suppresses line-frequency noise from unregulated AC/DC stages |
| Quiescent Current | 3.2–6.0 mA (typ/max) - enables low-static-power designs where idle current impacts battery life or thermal budget |
| Thermal Shutdown | Activates at TJ = +150°C - prevents permanent damage during sustained overload or poor heatsinking |
| Short-Circuit Limit | 0.2 A typical (TA = 25°C) - provides controlled fault current for fuse coordination and PCB trace safety |
Pinout & Package
D2PAK-3 (TO-263) surface-mount package with exposed thermal pad connected to Pin 2 (Ground); heatsink surface must be electrically tied to system ground for optimal thermal performance and EMI control.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input | Unregulated DC input (8.5–35 V); requires 0.33 µF bypass capacitor mounted directly across Pins 1–2 |
| 2 | Ground | Common reference for input, output, and thermal pad; all grounds must share low-impedance path to avoid regulation error |
| 3 | Output | Stable +6.0 V output; optional ≥0.1 µF ceramic capacitor improves transient response but not required for stability |
Key Features
| Feature | Design Value |
|---|---|
| No external components required | Self-contained regulation with integrated pass transistor, error amplifier, and protection - eliminates BOM cost and layout complexity |
| Internal thermal overload protection | Automatic shutdown at +150°C junction temperature with hysteresis - prevents irreversible silicon damage during fault conditions |
| Safe-area compensated output transistor | Current limit decreases as VCE rises - maintains SOA compliance across full input range without external foldback circuitry |
| ±2% output voltage tolerance | Tight initial accuracy at 25°C - reduces need for post-regulation trimming in precision analog or sensor signal chains |
| Pb-free and RoHS-compliant | Meets EU Directive 2011/65/EU - suitable for consumer, industrial, and automotive applications requiring environmental compliance |

FAQ
What is the maximum input voltage rating for MC7806BD2TR4?
The absolute maximum input voltage for MC7806BD2TR4 is 35 V DC, as specified in the "Maximum Ratings" table of the official onsemi datasheet. Operation above this voltage risks permanent device failure due to junction breakdown. For reliable long-term use, design input voltage to remain ≤30 V under worst-case ripple and surge conditions.
Does MC7806BD2TR4 require an input bypass capacitor?
Yes, MC7806BD2TR4 requires a 0.33 µF or larger low-ESR capacitor (e.g., tantalum or ceramic) placed directly between Pin 1 (Input) and Pin 2 (Ground). This capacitor stabilizes the regulator under fast load transients and prevents oscillation when input traces are long or inductive. Mounting it with minimal lead length is critical for effectiveness.
Can MC7806BD2TR4 be used without a heatsink?
MC7806BD2TR4 can deliver up to ~350 mA continuously without a heatsink at 25°C ambient, assuming sufficient PCB copper area (≥2 in² of 2 oz copper) under the thermal pad. At full 1.0 A load with 12 V input, power dissipation reaches ~6 W - requiring a heatsink to maintain TJ < 125°C. Thermal resistance junction-to-ambient is 65°C/W in D2PAK-3 with no heatsink.
What is the output voltage tolerance of MC7806BD2TR4 over temperature?
MC7806BD2TR4 maintains ±4% output voltage tolerance over its full operating junction temperature range (−40°C to +125°C), with ±2% guaranteed at 25°C. The average temperature coefficient is −0.4 mV/°C, meaning output drifts downward by ~0.4 mV per degree rise - a total shift of ~60 mV from −40°C to +125°C.
Is MC7806BD2TR4 pin-compatible with older TO-220 versions of the 7806 regulator?
MC7806BD2TR4 uses the D2PAK-3 (TO-263) package with identical pinout (Input-Ground-Output) as TO-220, but physical dimensions and thermal pad layout differ. While electrical pin functions match, PCB footprint and solder reflow profile must be redesigned for surface-mount assembly. It is not a drop-in mechanical replacement for through-hole TO-220 boards.
