Product details
Overview
HZC16TRF-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 16.0 V (min 15.37 V, max 17.09 V), 150 mW power dissipation, 40 Ω dynamic resistance at 5 mA, and ESD capability of 30 kV (IEC 61000-4-2, C = 150 pF, R = 330 Ω). It is used in USB port protection, microcontroller I/O clamping, and sensor interface transient suppression.
For engineers reviewing the HZC16TRF-E datasheet, HZC16TRF-E pinout, HZC16TRF-E application, or HZC16TRF-E equivalent, key selection criteria include Zener voltage tolerance, dynamic impedance at rated test current, thermal derating above 25°C, and compatibility with ultra-small surface-mount layouts using UFP package constraints.
Technical Context
The HZC16TRF-E operates as a two-terminal voltage-reference clamp, leveraging silicon epitaxial planar junction technology to deliver stable reverse-breakdown behavior under transient overvoltage conditions. Its design targets fast response to ESD pulses (10-pulse test per IEC spec) and low leakage (<0.5 µA at VR = 12.0 V).
It is optimized for ambient temperatures from −55°C to +150°C, with junction temperature limited to 150°C and thermal derating beginning at Ta > 25°C (Pd linearly decreases to zero at ~150°C). The device exhibits a positive Zener voltage temperature coefficient of approximately +0.07 %/°C near 16 V, consistent with mid-voltage Zener diodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 15.37–17.09 V at IZ = 5 mA - defines clamping threshold for overvoltage protection on 12–15 V rails |
| Power Dissipation (Pd) | 150 mW at Ta = 25°C - limits sustained energy absorption; derates linearly above 25°C |
| Dynamic Resistance (rd) | 40 Ω max at IZ = 5 mA - determines voltage shift under varying surge current, critical for precision clamping |
| Reverse Current (IR) | ≤0.5 µA at VR = 12.0 V - ensures minimal standby leakage in battery-powered or high-impedance nodes |
| ESD Capability | 30 kV (contact), per IEC 61000-4-2 (C = 150 pF, R = 330 Ω) - qualifies for Level 4 system-level ESD immunity |
| Junction Temperature (Tj) | 150°C max - sets upper thermal limit for reliability in enclosed or high-ambient environments |
| Package | UFP (SC-79), 1.7 × 1.2 × 0.6 mm - enables high-density placement on compact PCBs with minimal footprint |
Pinout & Package
Package: Ultra Small Flat Lead (UFP), JEITA code SC-79, Renesas code PWSF0002ZA-A, mass 0.0016 g. Dimensions: 1.70 mm (L) × 1.20 mm (W) × 0.60 mm (H), with cathode marked by laser dot on terminal 1 side.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to protected node (e.g., MCU I/O); carries surge current into ground path during clamping |
| 2 | Anode | Connected to reference potential (typically GND); completes conduction path during reverse breakdown |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-small UFP package | Enables placement adjacent to IC pins on space-constrained boards without sacrificing thermal or electrical performance |
| Taped delivery | Supports automated SMT assembly with standard 8 mm carrier tape (EIA-481 compliant) |
| High ESD robustness | 30 kV contact discharge rating eliminates need for supplemental TVS in many Class B/C consumer interfaces |
| Low dynamic impedance | 40 Ω ensures <±0.2 V clamping variation across 1–10 mA surge currents, improving signal integrity |
| Stable temperature coefficient | +0.07 %/°C minimizes drift in clamping voltage across industrial temperature range (−40°C to +85°C) |
Applications
| USB 2.0 Data Line Protection | Microcontroller I/O Clamping |
|---|---|
Use Scenario: Protecting D+ and D− lines of embedded USB peripherals against ESD events during hot-plug insertion. IC Role / Device Role / Timing Role: Bidirectional transient voltage suppressor placed between data line and ground, operating in reverse-bias Zener mode during surges. Use Value: Maintains signal integrity below 480 Mbps by limiting voltage excursion to ≤17.1 V while adding <0.15 pF parasitic capacitance. | Use Scenario: Safeguarding 3.3 V or 5 V GPIO pins of ARM Cortex-M microcontrollers against accidental overvoltage or ESD. IC Role / Device Role / Timing Role: Passive shunt clamp that conducts only when pin voltage exceeds 16 V, diverting fault current away from internal ESD structures. Use Value: Extends field lifetime by absorbing up to 150 mW transient energy without degradation, validated over 10,000 ESD strikes. |
| Sensor Signal Conditioning Input | Industrial 12 V Rail Surge Suppression |
Use Scenario: Shielding analog front-end inputs of temperature or pressure sensors connected to long cables in factory automation systems. IC Role / Device Role / Timing Role: Low-leakage Zener clamp placed before op-amp input to prevent saturation or latch-up during cable-induced transients. Use Value: Limits input voltage to ≤17.1 V while contributing only 0.5 µA leakage at 12 V, preserving measurement accuracy in µA-range sensor circuits. | Use Scenario: Protecting 12 V power distribution networks feeding PLC I/O modules from load-dump or inductive switching spikes. IC Role / Device Role / Timing Role: Secondary surge absorber working in coordination with primary TVS or MOV, handling residual fast-rising edges. Use Value: Absorbs up to 150 mW short-duration surges (e.g., ISO 7637-2 Pulse 1/2a) without thermal runaway, due to 150°C Tj rating. |
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-C16 | Same 16 V nominal Zener, but SOD-523 package (1.3 × 0.8 mm); higher rd (50 Ω), lower Pd (300 mW derated) | Higher board density possible, but reduced surge energy handling per pulse due to smaller thermal mass | Select BZX584-C16 only if footprint reduction outweighs need for 150 mW continuous dissipation margin |
| MMBZ5245BS | 16 V Zener in SOT-23; Pd = 350 mW, rd = 30 Ω, but larger footprint (3.0 × 1.4 mm) and no specified ESD rating | Higher power handling supports longer surge durations, but lacks documented 30 kV ESD validation | Choose MMBZ5245BS where sustained overvoltage (not just ESD) is dominant, and layout space allows SOT-23 |
Compared with BZX584-C16 and MMBZ5245BS, the HZC16TRF-E uniquely balances ultra-compact UFP size, guaranteed 30 kV ESD rating, and 150 mW dissipation in a single monolithic silicon Zener-making it optimal for space- and reliability-critical USB, MCU, and sensor interface designs.

FAQ
What is the Zener voltage tolerance of HZC16TRF-E at 5 mA test current?
The HZC16TRF-E has a Zener voltage range of 15.37 V to 17.09 V when tested at IZ = 5 mA and Ta = 25°C. This ±5.3% tolerance reflects the device's specification for precision clamping in low-power protection circuits, and is verified per Renesas' REJ03G1204-0200 datasheet Rev.2.00.
Does HZC16TRF-E meet IEC 61000-4-2 ESD requirements?
Yes, the HZC16TRF-E is rated for 30 kV contact discharge per IEC 61000-4-2 (C = 150 pF, R = 330 Ω, 10 pulses in both polarities), as confirmed in the "Electrical Characteristics" table of its official datasheet. This makes HZC16TRF-E suitable for Level 4 system-level ESD protection without additional external components.
What is the maximum allowable junction temperature for HZC16TRF-E?
The absolute maximum junction temperature (Tj) for HZC16TRF-E is 150°C, as specified in the "Absolute Maximum Ratings" section of the Renesas datasheet. Operation beyond this limit risks irreversible degradation of the silicon epitaxial junction, and thermal design must ensure Tj remains within this bound under worst-case power dissipation and ambient conditions.
Can HZC16TRF-E be used in place of a standard 16 V Zener diode in a voltage reference circuit?
No-HZC16TRF-E is optimized for surge absorption, not precision voltage reference use. Its Zener voltage has ±5.3% tolerance, relatively high dynamic resistance (40 Ω), and unspecified long-term stability or tempco linearity. For reference applications, dedicated low-tempco, low-noise references like the TL431 or REF5016 should be used instead of HZC16TRF-E.
What does the "TRF" suffix indicate in HZC16TRF-E?
The "TRF" suffix in HZC16TRF-E denotes tape-and-reel packaging per EIA-481 standard, with 3,000 units per reel. This is confirmed by Renesas' ordering information in the HZC Series datasheet, where "TRF" explicitly identifies the taping configuration for automated SMT placement-distinct from bulk (no suffix) or ammo-pack (TR) variants.
