Product details
Overview
RJE0621JSP-00#J0 from Renesas Electronics is a –60 V, –2 A P-channel thermal protection power switch with integrated overtemperature shutdown, current limiting, and hysteresis-based thermal recovery. It operates at logic-level gate drive (–3 V threshold), supports 12 V/24 V supply rails, and is AEC-Q101 qualified for automotive power distribution in engine control units and body electronics.
For engineers reviewing the RJE0621JSP-00#J0 datasheet, RJE0621JSP-00#J0 pinout, RJE0621JSP-00#J0 application, or RJE0621JSP-00#J0 equivalent, key selection criteria include its built-in thermal shutdown at 175°C junction temperature, 231 mΩ RDS(on) at –10 VGS, –2 A current limit, SOP-8 (FP-8DAV) package, and compatibility with short-circuit robust load switching in 12 V/24 V automotive systems.
Technical Context
This device integrates dual MOSFETs with independent gate resistors, self-return circuits, and parallel temperature-sensing paths feeding a hysteresis-controlled gate-shutdown circuit. Its thermal protection activates when channel temperature exceeds 175°C and recovers only after cooling to 145°C, preventing thermal runaway during sustained overload.
The RJE0621JSP-00#J0 features two-stage current limitation: first via gate voltage clamping under overcurrent, then hard current limiting at –2 A (typical), with avalanche energy rating of 69 mJ and maximum safe operating area validated up to –60 VDS and –2 A under pulse conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | –60 V: Maximum drain-source blocking voltage; enables use in 24 V automotive systems with margin against load dump transients. |
| ID (limit) | –2 A: Hard current limit value; ensures predictable fault current during short-circuit events without external sensing. |
| RDS(on) | 231 mΩ (typ) at VGS = –10 V: Low on-resistance minimizes conduction loss and self-heating in continuous 1 A load applications. |
| TSD / THR | 175°C / 145°C: Thermal shutdown and return temperatures with 30°C hysteresis; prevents oscillation during thermal recovery. |
| VGS(th) | –0.9 to –2.1 V: Logic-compatible gate threshold; allows direct drive from 3.3 V or 5 V microcontrollers without level shifting. |
| Avalanche Energy | 69 mJ: Rated single-pulse avalanche capability; supports inductive load switching without external snubbers in relay or solenoid drivers. |
| Package | SOP-8 (FP-8DAV), PRSP0008DD-D: Standard surface-mount footprint with 4 drain pins (pins 5–8) for enhanced thermal and current handling. |
Pinout & Package
Package: SOP-8 (FP-8DAV), 3.95 mm × 4.9 mm, 1.27 mm pitch, Ni/Pd/Au plating. Four drain terminals (pins 5–8) provide low-inductance, high-current path and improved thermal dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3 | Source | Common source connection for both internal MOSFETs; referenced to system ground or load return path. |
| 2, 4 | Gate | Logic-level input terminals; accept –3 V to –12 V drive; internally connected to thermal shutdown and current limit control circuits. |
| 5, 6, 7, 8 | Drain | Parallel drain outputs; handle combined –2 A load current and dissipate heat across four pins to reduce current density and thermal resistance. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated thermal shutdown | Self-contained junction temperature sensing and gate shutoff at 175°C - eliminates need for external thermistor or controller feedback loop. |
| Hysteresis-based recovery | Automatic re-enable only after channel cools to 145°C - prevents repeated tripping during marginal thermal conditions. |
| Built-in current limitation | Hard –2 A current clamp activated before thermal trip - provides deterministic fault current for fuseless design and predictable PCB trace sizing. |
| Logic-level gate drive | Operates with –3 V gate voltage - compatible with standard 3.3 V MCU GPIOs without external driver stages. |
| AEC-Q101 qualification | Validated for automotive temperature range (–40°C to +150°C) and mechanical stress - suitable for under-hood ECUs and body control modules. |
Applications
| Engine Control Unit Power Distribution | Automotive HVAC Blower Motor Control |

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel protected power switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NVMFS5C465N | –40 V, –120 A, no integrated thermal shutdown; requires external current sense and thermal monitoring. | Targeted at high-current, high-efficiency DC-DC converter primary side; lacks autonomous protection logic. | Choose when higher current capacity is needed and system-level protection is already implemented. |
| Infineon BTS4141N | –40 V, –6 A, integrated current sense output and diagnostic flag; thermal shutdown at 180°C (no hysteresis). | Designed for smart high-side switching with CAN/LIN diagnostics; not AEC-Q101 qualified in same grade. | Prefer when real-time current feedback and communication interface are required over autonomous thermal recovery. |
Compared with NVMFS5C465N and BTS4141N, the RJE0621JSP-00#J0 uniquely combines AEC-Q101 qualification, hysteresis-based thermal recovery, and logic-level drive in SOP-8 - making it optimal for cost-sensitive, space-constrained automotive load switches where autonomous fault management is critical.

FAQ
What is the maximum continuous drain current rating for RJE0621JSP-00#J0?
The RJE0621JSP-00#J0 has a rated continuous drain current of –2 A under specified thermal conditions (glass epoxy board, 40 × 40 × 1.6 mm). Its current-limiting circuit enforces a hard –2 A clamp during overload, ensuring predictable behavior without relying on external current sensing. This value is confirmed in the Absolute Maximum Ratings table and verified in the Electrical Characteristics section under ID limt.
Does RJE0621JSP-00#J0 require an external gate resistor for safe operation?
No, the RJE0621JSP-00#J0 integrates gate resistors internally (visible in the functional block diagram on page 1). These resistors are optimized for controlled turn-on/turn-off timing and EMI reduction. External gate resistors are unnecessary for basic operation but may be added for fine-tuning switching speed in noise-sensitive applications - though doing so does not affect thermal or current protection functionality.
How does the thermal shutdown hysteresis work in RJE0621JSP-00#J0?
The RJE0621JSP-00#J0 shuts down the gate drive when junction temperature reaches 175°C (Tsd) and remains off until temperature falls to 145°C (Thr), providing 30°C hysteresis. This prevents rapid cycling during marginal thermal conditions. The hysteresis is implemented in hardware within the gate-shutdown circuit and does not require external configuration or software control.
Is RJE0621JSP-00#J0 compatible with 3.3 V microcontroller GPIOs?
Yes, the RJE0621JSP-00#J0 supports logic-level operation down to –3 V gate drive (Vop = –3 to –12 V), making it directly compatible with 3.3 V MCU outputs. Its gate threshold voltage (VGS(off)) ranges from –0.9 V to –2.1 V, ensuring full enhancement at –3.3 V. No level shifter or gate driver is required for standard 3.3 V digital control signals.
What is the avalanche energy rating of RJE0621JSP-00#J0 and how is it used in design?
The RJE0621JSP-00#J0 is rated for 69 mJ of single-pulse avalanche energy (EAR) under test conditions of Tch = 25°C and Rg ≥ 50 Ω. This rating enables safe switching of inductive loads (e.g., relays, solenoids) without external snubber networks. Designers use this value to verify that expected inductive energy (½·L·I²) stays below 69 mJ during worst-case turn-off events.
