Product details
Overview
HZC15TRF-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 15 V (13.84–15.52 V), 150 mW power dissipation, and ultra-small UFP (SC-79) surface-mount package. It serves as a precision voltage clamp in ESD-sensitive interfaces, microcontroller I/O protection, and DC bias stabilization.
For engineers reviewing the HZC15TRF-E datasheet, HZC15TRF-E pinout, HZC15TRF-E application, or HZC15TRF-E equivalent, key selection criteria include Zener voltage tolerance (±5.5%), dynamic resistance (40 Ω at 5 mA), ESD capability (±30 kV per IEC 61000-4-2), and thermal derating above 25°C ambient.
Technical Context
The HZC15TRF-E operates as a two-terminal voltage reference and transient suppressor, leveraging silicon epitaxial planar construction for stable breakdown characteristics and low leakage. Its design targets low-energy surge events-such as ESD and inductive switching spikes-in space-constrained consumer and industrial electronics.
It exhibits a Zener voltage temperature coefficient of +0.07 %/°C (≈1.05 mV/°C) near 15 V, enabling predictable drift behavior across −55°C to +150°C operating range. The device is rated for 0.5 µA maximum reverse current at 11 V and supports pulsed Zener current up to 5 mA per specification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 13.84–15.52 V at 5 mA - defines clamping threshold for overvoltage protection |
| Power Dissipation (Pd) | 150 mW at Ta = 25°C - limits continuous energy handling without heatsinking |
| Dynamic Resistance (rd) | 40 Ω at IZ = 5 mA - determines voltage regulation stiffness under load variation |
| Reverse Current (IR) | ≤0.5 µA at VR = 11 V - ensures minimal leakage in standby bias networks |
| ESD Capability | ±30 kV (HBM, C = 150 pF, R = 330 Ω) - qualifies for direct I/O line protection without external TVS staging |
| Junction Temperature (Tj) | −55°C to +150°C - enables use in automotive under-hood or industrial control environments |

|---|---|
Use Scenario: Protecting 3.3 V or 5 V GPIO pins against ESD events during hot-plug or handling. IC Role / Device Role / Timing Role: Zener clamping diode placed between I/O line and ground to shunt transients before they reach MCU input structure.

Use Scenario: Safeguarding D+ and D− lines in USB 2.0 peripherals against ±8 kV contact ESD per IEC 61000-4-2. IC Role / Device Role / Timing Role: Low-capacitance (<1.5 pF typical) bidirectional clamp maintaining signal integrity up to 480 Mbps. Use Value: Enables direct-line protection without series impedance or RC filtering, preserving rise/fall time compliance. |

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 |
|---|---|---|---|
| BZX584-C15 (Nexperia) | Same 15 V nominal Zener, but ±5% tolerance (tighter), 300 mW Pd, SOD-523 package (1.3 × 0.85 mm) | Higher power handling allows longer surge duration; smaller footprint reduces parasitic inductance | Preferred where board space is tighter and surge energy exceeds 150 mW limits of HZC15TRF-E |
| MMBZ5245B (ON Semiconductor) | 15 V Zener, ±5% tolerance, 350 mW Pd, SOT-23 package (3.0 × 1.4 mm) | Larger thermal mass improves transient power dissipation; higher leakage (≤5 µA at 12 V) | Chosen when higher surge repetition rate or manual assembly compatibility is required |
Compared with BZX584-C15 and MMBZ5245B, the HZC15TRF-E offers superior ESD immunity (±30 kV vs. ±25 kV typical) and lower leakage (≤0.5 µA), making it optimal for ultra-low-power, ESD-critical signal paths despite its lower power rating.

FAQ
What is the Zener voltage tolerance of the HZC15TRF-E?
The HZC15TRF-E has a specified Zener voltage range of 13.84 V to 15.52 V at 5 mA test current, corresponding to ±5.5% tolerance about the nominal 15 V rating. This tolerance is verified per Renesas REJ03G1204-0200 Rev.2.00 and applies under standard test conditions (Ta = 25°C, pulse width = 40 ms). The HZC15TRF-E maintains this specification across its qualified operating temperature range.
Does the HZC15TRF-E meet industrial temperature requirements?
Yes, the HZC15TRF-E is rated for junction temperatures from −55°C to +150°C and storage temperatures over the same range. Its absolute maximum ratings and electrical characteristics are guaranteed across this span, supporting deployment in industrial control cabinets, motor drive feedback circuits, and outdoor sensor nodes where ambient extremes occur. The HZC15TRF-E is classified as a "Standard" quality grade device per Renesas documentation.
What is the dynamic resistance of the HZC15TRF-E and why does it matter?
The HZC15TRF-E exhibits a dynamic resistance of 40 Ω at 5 mA Zener current, as measured per Renesas REJ03G1204-0200. This value quantifies how tightly the device regulates voltage under varying current loads - lower rd means less voltage shift during transient surges. For the HZC15TRF-E, 40 Ω ensures clamping stays within ±0.2 V for ±8 mA current excursions, critical for protecting sensitive analog inputs.
Can the HZC15TRF-E be used for bidirectional ESD protection?
No - the HZC15TRF-E is a unidirectional Zener diode configured as a cathode-grounded shunt clamp. It conducts only when the cathode is driven ≥15 V above anode potential. For bidirectional protection (e.g., USB D+/D−), two HZC15TRF-E devices must be connected anode-to-anode or paired with a dedicated bidirectional TVS. The HZC15TRF-E's ±30 kV ESD rating applies only in its intended forward/reverse polarity configuration.
What package type does the HZC15TRF-E use and is it RoHS-compliant?
The HZC15TRF-E uses the Ultra Small Flat Lead (UFP) package, JEITA code SC-79, with dimensions 1.70 × 1.20 × 0.60 mm and Renesas package code PWSF0002ZA-A. Per Renesas environmental notices, the HZC15TRF-E complies with EU RoHS Directive requirements and contains no restricted substances above threshold limits. Full compliance documentation is available through Renesas' official product portal.
