Product details
Overview
HZC3.0TRF-E from Renesas Electronics is a silicon epitaxial planar Zener diode optimized for surge absorption in low-power signal and supply rail protection circuits, with a nominal Zener voltage of 3.0 V (2.8–3.2 V), 150 mW power dissipation, 120 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 interface protection, microcontroller I/O clamping, and sensor signal conditioning.
For engineers reviewing the HZC3.0TRF-E datasheet, HZC3.0TRF-E pinout, HZC3.0TRF-E application, or HZC3.0TRF-E equivalent, key selection criteria include its ultra-small UFP package (SC-79), low leakage (<1.0 µA at 1.0 V), tight Zener voltage tolerance, temperature coefficient of +0.03 %/°C, and suitability for high-density surface-mount designs requiring robust transient immunity without series impedance.
Technical Context
The HZC3.0TRF-E operates as a precision voltage reference and bidirectional transient voltage suppressor in clamp configurations. Its epitaxial planar structure ensures stable Zener breakdown with low dynamic resistance (120 Ω) and minimal voltage drift over temperature (±0.03 %/°C).
Designed for low-energy surge events, it delivers 30 kV ESD immunity in both forward and reverse directions per IEC 61000-4-2, with specified test conditions (10 pulses, C = 150 pF, R = 330 Ω) and failure criterion aligned to IR specification limits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

| Power Dissipation (Pd) | 150 mW at Ta = 25°C - supports continuous operation in compact PCB layouts without forced cooling |
| Dynamic Resistance (rd) | 120 Ω max at IZ = 5 mA - ensures minimal voltage shift under transient current surges up to 100 mA peak |
| Reverse Leakage (IR) | ≤1.0 µA at VR = 1.0 V - preserves signal integrity in high-impedance sensor interfaces |
| ESD Capability | ±30 kV (IEC 61000-4-2, C = 150 pF, R = 330 Ω) - provides system-level ESD robustness without external TVS staging |

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 |
|---|---|---|---|
| MMBZ5223BS-7-F (Diodes Inc.) | Zener voltage 3.0 V (2.85–3.15 V), 200 mW Pd, 100 Ω rd, SOD-523 package (1.7 × 1.3 × 0.9 mm) | Larger height (0.9 mm vs. 0.6 mm) may impact low-profile assemblies; higher Pd suits higher-energy transients | Select when board space allows taller profile and higher surge margin is required beyond 150 mW average dissipation. |
| BZX584-C3V0 (Nexperia) | Zener voltage 3.0 V (2.85–3.15 V), 300 mW Pd, 90 Ω rd, SOD-323 package (1.7 × 1.3 × 0.95 mm) | Higher power rating but larger footprint and height; lacks published ±30 kV ESD rating per IEC 61000-4-2 | Prefer where thermal design accommodates greater dissipation and ESD testing is performed at system level rather than component level. |
Compared with MMBZ5223BS-7-F and BZX584-C3V0, the HZC3.0TRF-E offers the lowest profile (0.6 mm height), verified ±30 kV ESD performance, and tighter Zener voltage distribution-making it optimal for space-constrained, high-reliability USB and sensor interface designs where component-level ESD compliance is mandatory.

FAQ
What is the Zener voltage tolerance of HZC3.0TRF-E at 5 mA test current?
The HZC3.0TRF-E has a Zener voltage range of 2.80 V to 3.20 V at IZ = 5 mA, representing a ±6.7% tolerance about the nominal 3.0 V value. This tolerance is guaranteed per Renesas' REJ03G1204-0200 datasheet Rev.2.00 and applies to all units shipped under this part number. The HZC3.0TRF-E maintains this specification across its qualified operating temperature range.
Does HZC3.0TRF-E meet IEC 61000-4-2 ESD requirements?
Yes, the HZC3.0TRF-E is rated for ±30 kV contact discharge per IEC 61000-4-2, tested with C = 150 pF and R = 330 Ω in both forward and reverse directions (10 pulses). This rating is explicitly confirmed in the "Electrical Characteristics" table of the official Renesas datasheet for HZC3.0TRF-E and applies to the device in its standard UFP package configuration.
What is the maximum junction temperature for HZC3.0TRF-E?
The maximum junction temperature (Tj) for HZC3.0TRF-E is 150°C, as specified in the "Absolute Maximum Ratings" section of the Renesas datasheet. This limit must not be exceeded during operation, and derating curves (Fig.2) show allowable power dissipation decreases linearly above 25°C ambient, reaching ~80 mW at 85°C ambient.
Is HZC3.0TRF-E compatible with lead-free reflow soldering processes?
Yes, the HZC3.0TRF-E's UFP package (PWSF0002ZA-A) is qualified for lead-free reflow soldering per J-STD-020. Its polyimide substrate and termination materials withstand peak temperatures up to 260°C for 10 seconds. The device carries RoHS compliance certification, and no special pre-bake or moisture sensitivity level (MSL) handling is required beyond standard MSL1 conditions.
What does the "TRF" suffix indicate in HZC3.0TRF-E?
The "TRF" suffix in HZC3.0TRF-E denotes tape-and-reel packaging per EIA-481 standard, with 3,000 units per reel. The "E" indicates compliance with RoHS Directive 2011/65/EU and halogen-free material content. This full designation confirms the part is supplied in automated assembly-ready format with environmental compliance fully documented by Renesas Electronics.
