Product details
Overview
HAF2012-92L from Renesas Electronics is a silicon N-channel MOSFET power switch with integrated over-temperature shutdown, logic-level gate drive (4–6 V), 60 V VDSS, 20 A continuous drain current, and 50 mΩ RDS(on) at VGS = 4 V - used in automotive body control modules for high-side load switching.
For engineers reviewing the HAF2012-92L datasheet, HAF2012-92L pinout, HAF2012-92L application, or HAF2012-92L equivalent, key selection criteria include thermal shutdown behavior, latch-type recovery requirement, LDPAK(L) package thermal performance, and short-circuit endurance under 24 V automotive loads.
Technical Context
This device integrates a temperature-sensing circuit and latch-type shutdown logic directly into the gate structure, triggering irreversible gate voltage cutoff when junction temperature exceeds 175 °C. It requires full gate voltage removal (0 V recovery) to reset.
Designed for high-side switching, it features a body-drain diode with 1.0 V forward voltage at 20 A and 110 ns reverse recovery time, alongside 40 A peak drain current capability under 10 µs pulses. Its static RDS(on) is specified at both 4 V and 10 V gate drive, supporting TTL-compatible and enhanced-efficiency operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 60 V - Maximum blocking voltage for 12/24 V automotive systems with load dump margin. |
| ID (continuous) | 20 A - Sustained load current rating at Tc = 25 °C, derated above case temperature. |
| RDS(on) | 50 mΩ max @ VGS = 4 V - Enables low conduction loss in logic-driven high-side switches. |
| Tsd | 175 °C - Junction temperature threshold for automatic thermal shutdown, protecting against overheating. |
| tos1 | 1.8 ms @ VDD = 12 V - Overload detection delay before shutdown activation under typical battery conditions. |
| VOP | 3.5–13 V - Valid gate operating voltage range compatible with 3.3 V and 5 V controllers. |
| Package | LDPAK(L) - Exposed-drain thermal package (PRSS0004AE-A) with 2.50 °C/W θch–c. |
Pinout & Package
Package: LDPAK(L) (Renesas code PRSS0004AE-A), surface-mount, thermally enhanced with exposed drain pad. Dimensions: 10.2 × 8.6 × 1.37 mm (L×W×H), mass 1.40 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Gate) | Control input | Logic-level input accepting 3.5–13 V; internal gate resistor and shutdown sensing circuitry connected here. |
| 2 (Drain) | High-side power output | Exposed metal pad - electrically and thermally connected to drain; must be soldered to PCB copper for thermal management. |
| 3 (Source) | Reference node | Common return path for load current; referenced to system ground in high-side configuration. |
| 4 (Drain) | Redundant drain connection | Second drain terminal - parallel-connected to Pin 2 for lower inductance and improved current sharing in high-frequency switching. |
Key Features
| Feature | Design Value |
|---|---|
| Latch-type thermal shutdown | Requires full gate voltage removal (0 V) to reset - prevents uncontrolled reactivation during fault conditions. |
| Short-circuit robustness | Withstands 40 A peak drain current (10 µs, 1% duty) without degradation - suitable for motor stall and lamp inrush protection. |
| Integrated temperature sensing | Senses junction temperature directly via on-chip circuit - eliminates need for external thermal sensors or compensation networks. |
| Body-diode optimized recovery | 110 ns trr and 1.0 V VDF at 20 A - reduces switching losses and voltage spikes in inductive load commutation. |
| Logic-level gate drive | Turns fully on at VGS = 4 V - compatible with standard microcontroller GPIOs without level-shifting circuitry. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side power switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STL220N6F7 | 60 V, 220 A rated, TO-220FP package; no integrated thermal shutdown - requires external protection circuitry. | Higher current capacity but larger footprint and no self-protection - suited for heatsink-mounted industrial drives, not space-limited automotive modules. | Select only if higher peak current (>40 A) and external thermal management are available; not drop-in for HAF2012-92L's latch-based safety function. |
| Infineon BTS724G | 42 V, 20 A, integrated diagnostics and PWM control; includes current sense and open-load detection - more complex feature set. | Designed for CAN/LIN-controlled smart power ICs in automotive ECUs - adds communication interface overhead not present in HAF2012-92L's pure analog switch architecture. | Choose when system-level diagnostics and serial control are required; HAF2012-92L remains optimal for simple, cost-sensitive high-side switching without MCU interaction. |
Compared with STL220N6F7 and BTS724G, the HAF2012-92L uniquely balances logic-level drivability, integrated latch-type thermal protection, and LDPAK(L) thermal efficiency - making it optimal for standalone high-side switching where simplicity, reliability, and board area are prioritized over diagnostics or ultra-high current.

FAQ
What is the thermal shutdown behavior of the HAF2012-92L?
The HAF2012-92L features a latch-type over-temperature shutdown that activates at 175 °C junction temperature. Once triggered, the gate voltage is cut off and remains latched until the gate is fully discharged to 0 V - requiring explicit system-level reset. This prevents automatic re-engagement during fault conditions and is confirmed in the "Typical Operation Characteristics" table on page 2 of the REJ03G1139-0400 datasheet. The HAF2012-92L implements this behavior via on-die temperature sensing and gate control circuitry.
Does the HAF2012-92L require an external flyback diode when driving inductive loads?
No, the HAF2012-92L incorporates a body-drain diode with characterized forward voltage (1.0 V at 20 A) and reverse recovery time (110 ns), enabling safe commutation of inductive loads without an external diode in many applications. However, for high-di/dt or high-energy inductive loads, an external Schottky diode may still be recommended to reduce voltage overshoot. This diode specification is explicitly provided in the "Electrical Characteristics" table on page 3 of the HAF2012-92L datasheet.
What is the maximum gate voltage the HAF2012-92L can tolerate?
The HAF2012-92L supports a maximum gate-to-source voltage (VGSS) of +16 V and –2.8 V, as specified in the Absolute Maximum Ratings table on page 2 of the REJ03G1139-0400 datasheet. Operating above +16 V risks permanent gate oxide damage. Its logic-level gate drive range (3.5–13 V) ensures compatibility with standard 3.3 V and 5 V controllers while maintaining margin below the absolute limit. This rating applies directly to the HAF2012-92L in its LDPAK(L) package.
How does the HAF2012-92L differ from the HAF2012-90L variant?
The HAF2012-92L and HAF2012-90L share identical electrical specifications, thermal characteristics, and LDPAK(L) packaging per the REJ03G1139-0400 datasheet. Their difference lies solely in ordering and packaging: HAF2012-92L uses a different tape-and-reel or sack configuration per Renesas' internal logistics coding, not functional differentiation. Both part numbers refer to the same silicon die and package construction - confirmed by identical parameter tables, pinouts, and application diagrams across all pages of the document.
Is the HAF2012-92L qualified for automotive applications?
Yes, the HAF2012-92L is designed for automotive use and falls under Renesas' "Standard" quality grade, which explicitly includes transportation equipment such as automobiles (per Note 7 on page 7 of REJ03G1139-0400). Its 150 °C channel temperature rating, –55 to +150 °C storage range, and robust short-circuit endurance align with AEC-Q101 stress test expectations. While formal AEC-Q101 certification status is not stated in the provided document, its specification envelope and intended use case confirm suitability for non-safety-critical automotive power switching functions.
