Product details
Overview
HZC10TRF-E from Renesas Electronics is a silicon epitaxial planar Zener diode designed for surge absorption in low-power signal and power rail protection circuits, with a nominal Zener voltage of 10.0 V (9.45–10.55 V), 150 mW power dissipation, 30 kV ESD capability (IEC 61000-4-2), and ultra-small UFP (SC-79) surface-mount package.
For engineers reviewing the HZC10TRF-E datasheet, HZC10TRF-E pinout, HZC10TRF-E application, or HZC10TRF-E equivalent, this device serves as a precision clamping element in I/O line protection, voltage reference stabilization, and transient suppression for microcontroller peripherals, sensor interfaces, and USB/UART level-shifting circuits where space-constrained, high-reliability Zener performance is required.
Technical Context
The HZC10TRF-E operates as a two-terminal, cathode-anode configured Zener diode optimized for stable reverse-biased breakdown at 10 V under 5 mA test current. Its epitaxial planar structure ensures tight voltage tolerance (±5.5%), low dynamic resistance (≤30 Ω), and predictable temperature coefficient (≈+0.06 %/°C).
Designed for surface-mount assembly on polyimide or FR-4 PCBs, it features a thermally robust junction capable of 150°C operation and withstands repeated ESD events up to ±30 kV in both forward and reverse directions per IEC 61000-4-2 (C = 150 pF, R = 330 Ω).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 9.45–10.55 V at IZ = 5 mA - defines precise clamping threshold for 10 V rail protection |
| Power Dissipation (Pd) | 150 mW at Ta = 25°C - limits continuous surge energy handling without derating |
| Dynamic Resistance (rd) | ≤30 Ω at IZ = 5 mA - ensures minimal voltage shift under varying transient current |
| ESD Capability | ±30 kV (IEC 61000-4-2) - provides robust immunity against human-body-model electrostatic discharge |
| Junction Temperature (Tj) | −55 to +150°C - supports operation in extended industrial ambient environments |
| Reverse Current (IR) | ≤0.5 µA at VR = 7.0 V - guarantees low leakage in standby and low-power modes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode surge absorption applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5240BLT1G (onsemi) | Zener voltage 10 V (±5%), Pd = 225 mW, rd = 17 Ω, SOT-23 package (larger than UFP) | Higher power rating suits higher-energy transients; larger footprint requires PCB redesign | Choose when >150 mW surge energy must be absorbed and board space permits SOT-23 |
| BZX84-C10 (Nexperia) | Zener voltage 10 V (±5%), Pd = 300 mW, rd = 20 Ω, SOT-23 package, ESD rated to ±30 kV | Same clamping voltage but double the power rating and different thermal profile | Prefer for cost-sensitive industrial designs where UFP size is not mandatory and higher Pd margin is needed |

FAQ
What is the Zener voltage tolerance of HZC10TRF-E?
The HZC10TRF-E has a guaranteed Zener voltage range of 9.45 V to 10.55 V at 5 mA test current, corresponding to ±5.5% tolerance. This tight specification ensures consistent clamping behavior across production lots and supports reliable design margins in 10 V rail protection circuits without additional calibration.
Does HZC10TRF-E meet industrial temperature requirements?
Yes, the HZC10TRF-E is rated for junction temperatures from −55°C to +150°C and storage temperatures from −55°C to +150°C. Its specified electrical characteristics-including Zener voltage, dynamic resistance, and leakage-are guaranteed at 25°C, with predictable drift modeled in the datasheet's temperature coefficient curve (≈+0.06 %/°C).
Is HZC10TRF-E compatible with lead-free reflow soldering?
Yes, the HZC10TRF-E uses standard Pb-free termination finish and is qualified for JEDEC J-STD-020D-compliant lead-free reflow profiles, including peak temperatures up to 260°C. The UFP package's thermal mass and polyimide-compatible construction ensure reliable solder joint formation without delamination or cracking.
How does the ESD rating of HZC10TRF-E compare to typical TVS diodes?
The HZC10TRF-E achieves ±30 kV contact discharge per IEC 61000-4-2-matching or exceeding many dedicated TVS diodes in the same package class. Unlike avalanche TVS devices, it relies on controlled Zener breakdown, offering tighter voltage control (±5.5%) but lower peak pulse power handling than multi-kW TVS arrays.
Can HZC10TRF-E be used as a voltage reference in precision analog circuits?
The HZC10TRF-E can serve as a moderate-precision reference in non-critical applications due to its stable 10 V Zener point and low dynamic resistance (≤30 Ω). However, it lacks curvature compensation and exhibits +0.06 %/°C tempco; for high-accuracy references, dedicated bandgap or buried-Zener ICs (e.g., REF5010) are recommended instead of HZC10TRF-E.
