Product details
Overview
MIC94030YM4-TR from Micrel is a 4-terminal P-channel MOSFET designed for high-side switching in space-constrained applications, featuring 0.75Ω typical RDS(on) at VGS = 4.5V, −13.5V VBDSS, and operation down to VGS = −2.7V; used in PCMCIA sleep-mode power control and distributed power management.
For engineers reviewing the MIC94030YM4-TR datasheet, MIC94030YM4-TR pinout, MIC94030YM4-TR application, or MIC94030YM4-TR equivalent, key selection criteria include its SOT-143 4-terminal package with isolated substrate, low-threshold P-channel switching capability, and thermal performance enabled by separate substrate-to-PCB heat sinking.
Technical Context
This device implements a silicon-gate P-channel enhancement-mode MOSFET architecture with a dedicated substrate terminal electrically isolated from source, enabling independent thermal and signal reference paths. Its gate threshold voltage (−0.6V to −1.4V) and sub-3V turn-on capability support direct interfacing with 3.3V logic without level shifting.
The 4-terminal SOT-143 configuration reduces θJA to 220°C/W and supports analog switch functionality by decoupling substrate bias from source potential-critical for minimizing charge injection and maintaining channel symmetry in bidirectional signal routing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBDSS | −13.5V minimum drain-source breakdown: ensures safe operation under transient overvoltage up to −16V pulse in 3.3V/5V rail systems. |
| RDS(on) @ VGS = −4.5V | 0.75Ω typical: enables ≤75mW conduction loss at 100mA load, suitable for low-power always-on circuitry. |
| RDS(on) @ VGS = −2.7V | 1.20Ω maximum: guarantees functional switching with 3.3V GPIOs even under worst-case process/temp corners. |
| ID Continuous @ TA = 25°C | −1A: supports single-load switching in portable peripherals without external heatsinking. |
| θJA | 220°C/W: requires minimal PCB copper area for thermal relief due to substrate-terminal heat path optimization. |
| VGS(th) | −0.6V to −1.4V: allows reliable turn-on with standard CMOS outputs while avoiding unintended conduction near ground. |
Pinout & Package
Package: SOT-143 (M4), 4-terminal surface-mount package with exposed substrate pad for enhanced thermal dissipation and analog switch integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Drain (D) | High-side switched output node | Connects to load supply rail; carries full load current when on; rated for −16V pulsed drain-source voltage. |
| Source (S) | Reference node for channel conduction | Biased at system ground or intermediate rail; defines VGS control voltage relative to gate. |
| Gate (G) | Control input for channel modulation | Accepts negative-going logic signals; internal ESD diode clamps positive excursions above VS. |
| Substrate (SS) | Independent bulk connection | Must be tied to source externally per datasheet; enables optimized thermal path and reduced body diode forward voltage in analog switch mode. |
Key Features
| Feature | Design Value |
|---|---|
| Separate substrate terminal | Enables independent thermal anchoring to PCB plane and eliminates source–bulk coupling in analog switch configurations. |
| Low VGS(th) range (−0.6V to −1.4V) | Guarantees robust turn-on with 3.3V microcontroller GPIOs without external level shifters or pull-down resistors. |
| 0.75Ω RDS(on) @ −4.5V | Reduces I²R losses below 75mW at 100mA, extending battery life in handheld scanners and PCMCIA cards. |
| −13.5V VBDSS | Provides 2.5× margin over 5V rail systems and withstands common 12V transient spikes in peripheral power domains. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel high-side switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMG2305UX-7 | RDS(on) = 0.45Ω @ −4.5V; SOT-23-3 package; no substrate terminal; higher ID rating (−4.2A). | Lacks isolated substrate; unsuitable for analog switch use; better for high-current digital load switching only. | Select when higher current capacity is required and thermal/analog performance is secondary. |
| SI2301DS-T1-E3 | RDS(on) = 0.115Ω @ −4.5V; SOT-23-3; no substrate terminal; VBDSS = −20V. | No substrate pin; higher VBDSS margin but incompatible with analog switch layouts requiring bulk isolation. | Prefer for cost-sensitive 5V/12V rail switching where substrate decoupling is unnecessary. |
Compared with DMG2305UX-7 and SI2301DS-T1-E3, the MIC94030YM4-TR uniquely provides a dedicated substrate terminal in SOT-143 for thermal and analog performance-making it irreplaceable in PCMCIA sleep control and bidirectional signal switching where bulk-source separation is mandatory.

FAQ
What is the maximum continuous drain current for MIC94030YM4-TR at 100°C ambient temperature?
The MIC94030YM4-TR supports −0.5A continuous drain current at TA = 100°C, as specified in its Absolute Maximum Ratings table. This derating reflects thermal limitations of the SOT-143 package and must be observed to maintain reliability. The device's 220°C/W θJA and substrate thermal path enable this performance without additional heatsinking on standard FR-4 PCBs.
Does MIC94030YM4-TR have an integrated gate pull-up resistor like MIC94031?
No, MIC94030YM4-TR does not include an internal gate pull-up resistor. That feature is exclusive to the MIC94031 variant. The MIC94030YM4-TR is the base 4-terminal P-channel MOSFET and requires external gate control circuitry-such as a microcontroller GPIO or open-drain driver-to ensure defined turn-on/off states.
Can MIC94030YM4-TR be used as an analog switch, and what is required for proper operation?
Yes, MIC94030YM4-TR supports analog switch operation due to its 4-terminal SOT-143 structure with isolated substrate. For correct function, the substrate (SS) pin must be externally connected to the source (S) pin, as mandated in the datasheet. This configuration minimizes charge injection and maintains symmetric on-resistance in bidirectional signal paths, such as in PCMCIA interface isolation.
What is the gate threshold voltage range for MIC94030YM4-TR, and how does it affect 3.3V logic compatibility?
The MIC94030YM4-TR has a gate threshold voltage range of −0.6V to −1.4V, meaning it reliably turns on with gate voltages ≤ −1.4V relative to source. When driven by a 3.3V GPIO referenced to ground, applying 0V to gate yields VGS = −3.3V-well within the turn-on range. This ensures full enhancement without level-shifting circuitry in standard 3.3V systems.
Is MIC94030YM4-TR RoHS-compliant and lead-free?
Yes, MIC94030YM4-TR is Pb-free and RoHS-compliant, as confirmed by its "YM4" ordering suffix and Micrel's July 2006 datasheet designation. The "Y" prefix indicates lead-free packaging, and the device meets JEDEC J-STD-020 moisture sensitivity level 1 requirements for standard SMT assembly processes.
