Product details
Overview
ZXTR2005P5-13 from Diodes Incorporated is a monolithic high-voltage linear regulator integrating an NPN transistor, zener diode, and 150kΩ current-limiting resistor in a single PowerDI5 package. It delivers a regulated 5V ±10% output at up to 42mA continuous current with input voltage range of 10V–100V, serving as a compact startup supply for DC-DC converters and PoE-powered devices.
For engineers reviewing the ZXTR2005P5-13 datasheet, ZXTR2005P5-13 pinout, ZXTR2005P5-13 application, or ZXTR2005P5-13 equivalent, key selection criteria include its 100V absolute maximum input rating, emitter-follower topology, integrated quiescent current limiting, thermal performance on 15mm×15mm copper, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
The ZXTR2005P5-13 implements a series linear regulator using an emitter-follower configuration with internal zener-based reference and fixed 150kΩ base resistor. Its regulation relies on VBE drop across the integrated transistor and zener clamping, enabling stable 5V output without external feedback components.
It operates over -40°C to +125°C junction temperature, supports safe operating area (SOA) compliance up to 740mA pulsed output at VIN=48V, and features 4000V HBM ESD protection. Thermal resistance is 107°C/W (Junction-to-Ambient, 15mm×15mm copper), and power dissipation is derated above 25°C ambient per published curve.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.0 V ±10% - delivers stable rail for logic-level biasing and gate drive in high-side startup circuits |
| Input Voltage Range | 10 V to 100 V - enables direct connection to PoE midspan, telecom battery, or industrial HV rails without pre-regulation |
| Continuous Output Current | 42 mA @ VIN = 48 V - sufficient to power control ICs and bias circuits during converter startup phase |
| Quiescent Current | 260–900 µA - set by internal 150kΩ resistor; enables low-power operation while maintaining regulation |
| Thermal Resistance θJA | 107 °C/W - measured on 15mm×15mm 1oz Cu PCB; defines max power before thermal shutdown at 125°C |
| PSRR | 45 dB @ 100 Hz - suppresses ripple from noisy HV input sources such as rectified AC or switching node coupling |
| Line Regulation | 300 mV - variation over 10–72V input; ensures consistent VOUT despite wide input swings |
| Load Regulation | -400 mV - variation from 0.1mA to 100mA load; maintains accuracy under dynamic control IC current draw |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | High-voltage input supply | Accepts -0.3V to 100V; exposed pad must be soldered to ≥15mm×15mm copper for thermal management |
| GND | Power ground reference | Common return path for input and output; connects internally to emitter and zener cathode |
| VOUT | Regulated 5V output | Emitter-follower output; requires ≥10µA minimum load and 10µF bypass capacitor for stability |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage linear regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ALD110800S (Advanced Linear Devices) | Discrete MOSFET + zener solution; no integrated resistor; requires external 150kΩ gate resistor | Lacks monolithic integration; higher layout sensitivity and thermal mismatch risk | Select when needing adjustable output via external zener or higher SOA flexibility |
| LT3080 (Analog Devices) | Adjustable current-source-based LDO; requires external SET resistor; 36V max input | Cannot operate directly from 48V+ PoE or telecom rails without pre-regulation | Select only if input is ≤36V and precise programmable output is required |
Compared with ALD110800S and LT3080, the ZXTR2005P5-13 uniquely combines 100V input capability, monolithic integration, and AEC-Q101 qualification-making it optimal for space-constrained, high-reliability PoE and telecom startup supplies where external component count and thermal robustness are critical.

FAQ
What is the minimum load required for regulation?
The ZXTR2005P5-13 requires a minimum load of 10µA on VOUT to maintain regulation. This is due to the internal zener and transistor biasing scheme-insufficient load causes VOUT to rise above 5V. A 10µF ceramic capacitor to GND is also recommended for stability under dynamic loads.
Can ZXTR2005P5-13 be used with input voltages below 10V?
Yes, but regulation is not guaranteed. When VIN < 10V, VOUT follows VIN minus ~1.5V (VBE drop), so output becomes unregulated and drops linearly. For example, at VIN = 8V, VOUT ≈ 6.5V; at VIN = 5V, VOUT ≈ 3.5V. Use only above 10V for 5V regulation.
How does thermal performance change between 15mm×15mm and 50mm×50mm copper areas?
On 15mm×15mm 1oz copper, RθJA = 107°C/W; on 50mm×50mm, it improves to 55°C/W. This means at 42mA output and 48V input (1.8W dissipation), junction temperature rises ~193°C above ambient on small copper-exceeding 125°C limit-so 50mm×50mm or thermal vias are mandatory for full-load operation.
Is ZXTR2005P5-13 pin-compatible with other PowerDI5 regulators?
No-ZXTR2005P5-13 has a unique 3-pin PowerDI5 pinout (VIN-GND-VOUT) with VIN on the exposed pad. Other PowerDI5 regulators (e.g., AP2331, DMN3028L) use different pin assignments and topologies (MOSFETs, Schottky diodes). Layout and thermal pad routing must be verified per device datasheet.
