Renesas HZC5.6TRF-P-E

Overview

HZC5.6TRF-P-E from Renesas Electronics is a silicon epitaxial planar Zener diode optimized for surge absorption in low-power signal-line protection circuits, featuring a nominal Zener voltage of 5.6 V (min 5.31 V, max 5.92 V), 150 mW power dissipation, 80 Ω dynamic resistance at 5 mA, and ±30 kV ESD capability per IEC 61000-4-2 (C = 150 pF, R = 330 Ω). It is used in USB data lines, sensor interface inputs, and microcontroller I/O port clamping.

For engineers reviewing the HZC5.6TRF-P-E datasheet, HZC5.6TRF-P-E pinout, HZC5.6TRF-P-E application, or HZC5.6TRF-P-E equivalent, key selection criteria include Zener voltage tolerance, low dynamic impedance for fast transient suppression, ultra-small UFP package footprint, ESD robustness, and thermal derating behavior above 25°C ambient.

Technical Context

The HZC5.6TRF-P-E operates as a two-terminal voltage-reference clamp, conducting in reverse bias when transient voltage exceeds its Zener breakdown threshold. Its planar epitaxial structure ensures stable breakdown characteristics and low leakage across temperature.

Designed specifically for surface-mount surge absorb applications, it delivers consistent clamping performance with 5 µA maximum reverse current at 2.5 V and a temperature coefficient of approximately +0.03 %/°C near 5.6 V - confirmed by Fig.2 in the datasheet - enabling predictable behavior in consumer-grade ambient ranges.

FAQ

What is the Zener voltage tolerance of HZC5.6TRF-P-E at 5 mA test current?

The HZC5.6TRF-P-E has a specified Zener voltage range of 5.31 V to 5.92 V when tested at I_Z = 5 mA, corresponding to ±5.5% tolerance about the nominal 5.6 V value. This tight spread ensures consistent clamping behavior across production lots and supports reliable design margins in 5 V system interfaces. The HZC5.6TRF-P-E datasheet (Rev. 2.00, page 2) confirms these limits under standard test conditions.

Does HZC5.6TRF-P-E meet IEC 61000-4-2 Level 4 ESD requirements?

Yes, the HZC5.6TRF-P-E is rated for ±30 kV contact discharge per IEC 61000-4-2, exceeding Level 4 (±8 kV contact / ±15 kV air) requirements. This rating is verified using C = 150 pF and R = 330 Ω, with failure criterion aligned to IR specification. The HZC5.6TRF-P-E achieves this without external components, making it suitable as a standalone ESD protection device in certified end equipment.

What is the maximum allowable ambient temperature for continuous operation of HZC5.6TRF-P-E at full 150 mW power dissipation?

The HZC5.6TRF-P-E supports full 150 mW power dissipation only at T_a = 25°C. Its derating curve (Fig.2, page 4) shows linear reduction to zero dissipation at 150°C junction temperature, implying a maximum ambient temperature of approximately 100°C when mounted on a standard FR-4 PCB with minimal copper area. For reliable long-term operation, ambient temperature should be kept ≤85°C with appropriate thermal relief.

Is HZC5.6TRF-P-E compatible with lead-free reflow soldering processes?

Yes, the HZC5.6TRF-P-E uses lead-free terminations and is qualified for standard Pb-free reflow profiles, including peak temperatures up to 260°C for 10 seconds. Its UFP package (PWSF0002ZA-A) and internal construction comply with JEDEC J-STD-020D moisture sensitivity level (MSL) 1, eliminating bake requirements prior to assembly. The HZC5.6TRF-P-E meets RoHS Directive 2011/65/EU as confirmed in Renesas' environmental compliance documentation.

How does the temperature coefficient of HZC5.6TRF-P-E affect clamping voltage stability over industrial temperature ranges?

The HZC5.6TRF-P-E exhibits a Zener voltage temperature coefficient of approximately +0.03 %/°C near 5.6 V (per Fig.2, page 4), resulting in a total shift of ~±0.17 V across −40°C to +85°C. This translates to a clamping window of 5.14–6.09 V in worst-case conditions - still within safe margins for 5 V logic interfaces. The HZC5.6TRF-P-E's positive tempco also improves stability versus negative-coefficient alternatives in varying ambient conditions.
