Product details
Overview
ZHCS506TC from Diodes Incorporated is a surface-mount Schottky barrier diode rated for 60 V reverse voltage, 500 mA continuous forward current, and 630 mV maximum forward voltage at 500 mA, used in DC–DC converters and mobile telecom power rails.
For engineers reviewing the ZHCS506TC datasheet, ZHCS506TC pinout, ZHCS506TC application, or ZHCS506TC equivalent, key selection criteria include low VF at high IF, AEC-Q101 qualification, SOT23 package compatibility, and 40 µA max reverse leakage at 45 V.
Technical Context
This Schottky diode employs a planar epitaxial construction with a low-barrier metal–semiconductor junction to minimize forward conduction loss and enable fast switching (trr ≤ 10 ns). Its thermal design supports 125°C maximum junction temperature and 330 mW power dissipation at 25°C ambient.
The device operates with reverse breakdown ≥60 V (tested at 200 µA), exhibits capacitance of 20 pF at 1 MHz/25 V, and maintains VF ≤ 630 mV across its full 500 mA rated current - critical for high-efficiency buck converter freewheeling paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum reverse blocking voltage before breakdown; ensures safe operation in 48 V input DC–DC stages. |
| IO | 500 mA - Continuous forward current rating; supports compact point-of-load regulators without derating at +25°C. |
| VF (max) | 630 mV @ 500 mA - Low conduction loss directly reduces power stage inefficiency and thermal load in portable power supplies. |
| IR (max) | 40 µA @ 45 V - Low leakage preserves standby efficiency in battery-powered telecom modules. |
| trr | ≤10 ns - Fast recovery enables high-frequency (>1 MHz) switching without significant reverse recovery loss. |
| PD | 330 mW @ TA = +25°C - Power dissipation limit defines PCB copper area requirements for thermal management. |
| Junction Temp | +125°C max - Enables reliable operation in sealed industrial enclosures without active cooling. |
Pinout & Package
Package: SOT23 - Surface-mount plastic case, 0.0089 g mass, UL 94V-0 rated, moisture sensitivity level 1, matte tin-plated Alloy 42 leadframe.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Forward current entry | Connected to switch node in synchronous buck topologies; requires low-inductance routing to minimize ringing. |
| Cathode (Pin 2) | Forward current exit / reverse voltage reference | Connected to output capacitor ground; serves as return path for freewheeling current during high-side FET off-time. |
| No-connect (Pin 3) | Thermal pad / mechanical anchor | Not electrically connected; provides mechanical stability and minor thermal relief via PCB copper exposure. |
Key Features
| Feature | Design Value |
|---|---|

| Lead-free & RoHS compliant | No purposely added lead; fully compliant with EU Directive 2011/65/EU - eliminates hazardous substance risk in global manufacturing. |
| SOT23 footprint | Standardized 3-pin outline (2.9 × 1.3 × 1.0 mm) enables drop-in replacement and automated assembly on legacy and new PCBs. |
Applications
| DC–DC Buck Converters | Mobile Telecom Power Rails |
|---|---|
Use Scenario: Freewheeling diode in non-synchronous 5 V/3.3 V buck converters powering baseband processors in 4G LTE handsets. IC Role / Device Role: Provides low-loss current path during high-side MOSFET off-time; replaces synchronous rectifier where cost or layout constraints apply. Use Value: 630 mV VF at 500 mA reduces conduction loss by >35% vs. standard PN diodes, extending battery runtime. | Use Scenario: Reverse polarity protection and voltage clamping in USB-powered peripheral modules with hot-swap capability. IC Role / Device Role: Blocks reverse current flow while limiting forward drop during normal operation; absorbs transient energy during plug/unplug events. Use Value: 10 ns trr prevents latch-up during rapid voltage transients; 40 µA IR minimizes quiescent drain in always-on circuits. |
| PCMCIA Card Interfaces | Industrial Sensor Node Power Supplies |
Use Scenario: Isolation and voltage translation between 3.3 V host logic and 5 V PCMCIA card peripherals in ruggedized data acquisition systems. IC Role / Device Role: Level-shifting clamp diode that prevents back-driving of host supply while enabling bidirectional signal integrity. Use Value: 60 V VRRM accommodates ±15 V transients common in card insertion; SOT23 size fits tight connector footprints. | Use Scenario: Input rectification and hold-up in ultra-low-power 24 V AC/DC converters powering wireless vibration sensors in predictive maintenance gateways. IC Role / Device Role: Converts transformer secondary output to stable DC; handles intermittent surges during motor startup events. Use Value: 5.5 A IFSM (100 µs) withstands short-duration inrush without failure; +125°C TJ rating ensures longevity in unventilated enclosures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MBR0560T1G | Same 60 V VRRM, 500 mA IO, but VF = 600 mV typ @ 500 mA; SOD-123 package (larger footprint). | Requires PCB redesign due to different package; higher thermal resistance limits power density. | Select if board space allows larger package and lower typical VF is prioritized over footprint. |
| SS54 | 60 V VRRM, 5 A IO, VF = 500 mV typ @ 5 A; DO-214AC package - significantly larger and higher IR (200 µA). | Over-specified current rating increases cost and board area; unsuitable for space-constrained mobile designs. | Choose only when higher surge current handling (5.5 A IFSM) is insufficient and discrete heat sinking is available. |
Compared with MBR0560T1G and SS54, ZHCS506TC delivers optimal balance of low VF, AEC-Q101 reliability, and minimal SOT23 footprint - making it preferred for high-density, thermally constrained telecom and industrial edge nodes.

FAQ
What is the maximum junction temperature for ZHCS506TC?
The absolute maximum junction temperature is +125°C. This rating is validated per AEC-Q101 stress tests and defines the upper thermal limit for reliable operation. Derating is required above +25°C ambient to maintain 330 mW power dissipation - e.g., at +85°C ambient, max allowable PD drops to ~180 mW based on thermal resistance calculations.
Is ZHCS506TC suitable for automotive applications?
Yes - ZHCS506TC is explicitly qualified to AEC-Q101 standards, covering temperature cycling, high-temperature reverse bias, and ESD robustness. It is approved for use in automotive infotainment, telematics, and body control modules where 60 V blocking and 500 mA current capability are required.
How does the SOT23 pinout differ from standard diode marking conventions?
In ZHCS506TC's SOT23 package, Pin 1 is Anode, Pin 2 is Cathode, and Pin 3 is a non-connected thermal pad. This matches JEDEC MO-203-AB and differs from some dual-diode SOT23 variants where Pin 3 may be shared. The cathode stripe on the top surface aligns with Pin 2, confirming polarity orientation during placement.
Can ZHCS506TC replace a standard PN rectifier in existing designs?
Yes, provided reverse voltage and surge current requirements are met. Its 60 V VRRM and 5.5 A IFSM match many 1N400x-class replacements, but the lower VF (630 mV vs. ~1.1 V) reduces conduction loss and thermal stress. Layout must verify SOT23 footprint compatibility and ensure no cathode-anode reversal during substitution.
