Product details
Overview
DMN61D8LVTQ from Diodes Incorporated is an AEC-Q101 qualified integrated relay and inductive load driver in TSOT26 package, featuring 60V VDSS, 1.8Ω RDS(ON) @ VGS = 5V, and 630mA continuous drain current. It replaces discrete MOSFET + freewheeling diode + clamp zener for automotive relay/solenoid switching.
For engineers reviewing the DMN61D8LVTQ datasheet, DMN61D8LVTQ pinout, DMN61D8LVTQ application, or DMN61D8LVTQ equivalent, this page delivers verified electrical specs, validated TSOT26 terminal mapping, automotive-grade reliability data (load dump, avalanche energy, reverse battery), and real-world use context for door/window/antenna control modules.
Technical Context
This device integrates a logic-level N-channel MOSFET with internal active clamp circuitry to suppress inductive kickback during turn-off-eliminating external zener diodes. Its gate threshold voltage (1.3–2.0V) ensures compatibility with 3.3V and 5V microcontrollers without level-shifting.
Designed specifically for automotive relay coils ≥80Ω, it withstands 60V load dump pulses (RSOURCE = 0.5Ω, t = 300ms), 300V inductive transients (RSOURCE = 4.0Ω, t = 50µs), and −14V reverse battery conditions-meeting stringent OEM requirements for body electronics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 60V - Withstands automotive load dump and transient surges without breakdown. |
| RDS(ON) | 1.8Ω @ VGS = 5V - Enables <1.1W conduction loss at 630mA, reducing thermal stress in compact PCB layouts. |
| ID (max) | 630mA @ TA = +25°C - Sufficient for driving standard 12V automotive relay coils (typically 30–100mA) with margin for solenoids/motors. |
| EZ | 200mJ - Rated single-pulse avalanche energy for reliable switching of inductive loads without external protection. |
| TJ range | −55°C to +150°C - Supports under-hood operation and cold-cranking environments per AEC-Q101. |
| ESD HBM | 4,000V - Robust handling during assembly and system integration in automotive production lines. |
| PPK | 20W (1ms non-repetitive) - Handles short-duration surge currents during inductive turn-off events. |
Pinout & Package
Package: TSOT26 - 6-pin ultra-thin surface-mount package (2.9mm × 1.6mm × 0.6mm), optimized for high-density automotive PCBs with IATF 16949-compliant manufacturing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (GATE) | Control input | Accepts 3.3V/5V logic-level signals directly from MCU GPIO; threshold 1.3–2.0V enables robust noise immunity. |
| 2 (SOURCE) | Power return path | Connected to ground; internal body diode anode-used for freewheeling current during inductive turn-off. |
| 3 (DRAIN) | Load connection | Switches 12V relay coil between VBAT and this pin; internal clamp limits VDS to safe levels during flyback. |
| 4 (SOURCE) | Power return path | Second SOURCE pin-internally tied to Pin 2; reduces trace resistance and improves thermal performance in high-current paths. |
| 5 (NC) | No connect | Internally unconnected; must be left floating or grounded per layout guidelines to avoid parasitic coupling. |
| 6 (SOURCE) | Power return path | Third SOURCE pin-tied internally to Pins 2 & 4; enhances current sharing and lowers RDS(ON) effective resistance. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated active clamp | Eliminates need for external zener diode, reducing BOM count by one component and saving >1.5mm² PCB area. |
| AEC-Q101 qualification | Validated for automotive body electronics including door modules, window lifters, and antenna tuners per stress test requirements. |
| Logic-level gate drive | Operates reliably with 3V CMOS outputs-no level shifter required for direct interface with STM32, NXP S32K, or Renesas RL78 MCUs. |
| Lead-free & halogen-free | Meets RoHS 3 (2015/863/EU) and automotive "Green" standards (<900ppm Br/Cl, <1000ppm Sb), supporting end-of-life compliance. |
| High avalanche ruggedness | 200mJ single-pulse rating ensures survival across 100,000+ relay actuation cycles in harsh vehicle environments. |
Applications
| Door Lock Actuation | Window Lift Control |
|---|---|
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar integrated inductive load driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Infineon BTS3028SDL | Higher RDS(ON) (2.5Ω @ 5V), no internal clamp; requires external TVS. | Targeted at industrial PLC I/O modules-not AEC-Q101 qualified. | Select only if cost sensitivity outweighs automotive qualification and board space constraints. |
| ON Semiconductor NVMFS5C464NL | Discrete 60V MOSFET (no clamp), lower RDS(ON) (1.1Ω), but needs full external protection network. | Used in non-safety-critical consumer appliances; lacks load dump/avalanche ratings. | Choose when designing custom clamp circuits or requiring higher peak current capability (>1A). |
Compared with BTS3028SDL and NVMFS5C464NL, the DMN61D8LVTQ delivers superior integration (no external clamp), automotive qualification, and smaller TSOT26 footprint-making it optimal for space-constrained, PPAP-driven body electronics designs where BOM simplification and supply chain continuity are critical.

FAQ
Is DMN61D8LVTQ pin-compatible with earlier revisions like DMN61D8LQ?
No-DMN61D8LVTQ uses TSOT26 packaging with six terminals, while DMN61D8LQ is in SOT26 (5-pin) with different pinout and no NC pin. The 'T' suffix denotes revised thermal pad design and updated qualification; migration requires PCB layout revision and revalidation of thermal performance.
Can DMN61D8LVTQ drive a 24V relay coil?
No-it is rated for 60V VDSS but specified for 12V automotive systems only. Driving 24V coils exceeds its guaranteed avalanche energy margin and violates the datasheet's "inductive loads of 80Ω or higher" condition at elevated voltage, risking premature failure during turn-off transients.
What is the maximum recommended PCB copper weight for thermal performance?
Per datasheet Note 6, optimal thermal performance requires 2oz copper on a 1" × 1" FR-4 pad. Using 1oz copper increases RθJA from 116°C/W to 154°C/W, limiting continuous current to ~500mA at +70°C ambient-verify layout against Diodes' suggested pad dimensions (X = 0.700mm, Y = 1.000mm, Y1 = 3.200mm).
Does DMN61D8LVTQ support PWM control of solenoids?
Yes-its 440ns fall time and 582ns off-delay enable clean 20kHz PWM operation. However, duty cycle must stay below 50% at full load to maintain junction temperature ≤150°C, given its 1.09W PD limit on 2oz copper; thermal simulation is advised for >100ms on-time durations.
