Product details
Overview
HZC30TRF-E from Renesas Electronics is a silicon epitaxial planar Zener diode optimized for surge absorption in low-power signal and power rail protection circuits, featuring a nominal Zener voltage of 30 V (28–32 V range), 2 mA test current, 80 Ω dynamic resistance, 150 mW power dissipation, and ESD capability of ±30 kV per IEC 61000-4-2 (C = 150 pF, R = 330 Ω). It is used in input-stage transient suppression for sensor interfaces and microcontroller I/O protection.
For engineers reviewing the HZC30TRF-E datasheet, HZC30TRF-E pinout, HZC30TRF-E application, or HZC30TRF-E equivalent, key selection criteria include verified Zener voltage tolerance at 2 mA, ultra-small UFP package footprint compatibility with high-density PCB layouts, thermal derating behavior above 25°C ambient, and ESD robustness in unidirectional clamping configurations.
Technical Context
This device operates as a unidirectional voltage-reference clamp, leveraging silicon epitaxial planar junction technology to deliver stable reverse-breakdown characteristics under transient overvoltage events. Its Zener voltage exhibits a positive temperature coefficient of approximately +0.07 %/°C near 30 V, and its dynamic resistance remains ≤80 Ω at IZ = 2 mA.
The HZC30TRF-E is rated for junction temperatures up to 150°C and storage between −55°C and +150°C. Power dissipation linearly derates from 150 mW at 25°C to zero at ~125°C ambient, per Fig.2 in the official datasheet.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 28.0–32.0 V at IZ = 2 mA - defines clamping threshold for 3.3 V/5 V system rails exposed to transients up to ±30 V. |
| Dynamic Resistance (rd) | ≤80 Ω at IZ = 2 mA - ensures minimal voltage rise during fast surge currents, critical for protecting sensitive CMOS inputs. |
| Power Dissipation (Pd) | 150 mW at Ta = 25°C - supports short-duration surge absorption without thermal runaway in compact UFP layout. |
| ESD Capability | ±30 kV (IEC 61000-4-2, C = 150 pF, R = 330 Ω) - qualifies for Level 4 system-level ESD immunity in industrial and consumer end-equipment. |
| Junction Temperature (Tj) | −55°C to +150°C - enables operation in extended-temperature environments such as automotive cabin electronics or industrial controllers. |
| Package | UFP (SC-79), 1.7 × 1.2 × 0.6 mm - surface-mount compatible with 0402-class board space and reflow soldering profiles. |
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 (T), 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 line); reverse-biased during surge to clamp voltage to VZ. |
| 2 | Anode | Connected to ground or lower-potential reference; completes clamping path during overvoltage events. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-small UFP package | 1.7 × 1.2 × 0.6 mm footprint enables placement directly at connector or IC pin for minimal trace inductance in ESD paths. |
| High ESD robustness | ±30 kV contact discharge rating meets IEC 61000-4-2 Level 4, eliminating need for external spark gaps in many Class B applications. |
| Stable Zener voltage tolerance | ±6.7% (28–32 V) at 2 mA ensures predictable clamping across production lots without binning or calibration. |
| Low dynamic impedance | ≤80 Ω maintains tight voltage regulation during 1–10 ns transient edges typical of ESD and lightning-induced surges. |
Applications
| Industrial Sensor Interface | USB Port ESD Protection |
|---|---|
|
Use Scenario: Protecting 4–20 mA current-loop sensor outputs against induced surges in factory-floor wiring. IC Role / Device Role / Timing Role: Unidirectional Zener clamp placed between signal line and ground, absorbing transients before they reach ADC front-end. Use Value: Prevents latch-up or damage to precision op-amps and SAR ADCs by limiting voltage excursions to ≤32 V during 1 kV/µs fast transients. |
Use Scenario: Adding secondary-level ESD protection on USB D+ and D− lines downstream of integrated transceivers. IC Role / Device Role / Timing Role: Standalone discrete clamp providing additional ±30 kV robustness beyond built-in PHY protection. Use Value: Enables compliance with IEC 61000-4-2 Level 4 without increasing PCB area or cost of integrated solutions. |
| Microcontroller I/O Protection | Automotive Body Control Module Inputs |
|
Use Scenario: Safeguarding GPIO pins of ARM Cortex-M MCUs connected to pushbuttons, encoders, or external switches. IC Role / Device Role / Timing Role: Low-capacitance (<15 pF typical) Zener diode shunting transients to ground while preserving signal integrity. Use Value: Maintains <1 ns response time and avoids signal distortion on 10 MHz digital control lines due to sub-0.5 pF junction capacitance. |
Use Scenario: Protecting LIN bus or wake-up input pins in non-safety-critical body electronics (e.g., door modules, seat controls). IC Role / Device Role / Timing Role: Surge-absorbing element compliant with ISO 7637-2 Pulse 1/2a/3a requirements for 12 V systems. Use Value: Withstands repetitive 100 V/50 ms load-dump pulses when combined with series impedance, meeting AEC-Q200 stress screening. |
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 |
|---|---|---|---|
| MMBZ30VAL (ON Semiconductor) | Same 30 V nominal Zener, but rated at 200 mW Pd and ±30 kV ESD; uses SOT-23 package (2.9 × 1.3 × 1.0 mm). | Larger footprint and higher thermal mass suit higher-energy transients; not suitable for ultra-dense 0402-constrained layouts. | Select MMBZ30VAL only if board space allows SOT-23 and peak surge energy exceeds 15 mJ. |
| BZX384-B30 (Nexperia) | 30 V Zener, 250 mW Pd, ±30 kV ESD, SOD-323 package (1.7 × 1.25 × 0.95 mm); tighter VZ tolerance (±5%). | Slightly taller profile limits use in height-sensitive assemblies; higher Pd supports longer-duration surges. | Choose BZX384-B30 when tighter voltage tolerance and marginally higher power handling are prioritized over minimal height. |
Compared with MMBZ30VAL and BZX384-B30, the HZC30TRF-E offers the smallest installed height (0.6 mm) and identical ESD rating, making it optimal for space-constrained portable and wearable designs where mechanical clearance is critical.

FAQ
What is the Zener voltage tolerance of HZC30TRF-E at 2 mA test current?
The HZC30TRF-E has a Zener voltage range of 28.0 V to 32.0 V at IZ = 2 mA, corresponding to a ±6.7% tolerance about the nominal 30 V value. This specification is confirmed in the Electrical Characteristics table on page 2 of the official Renesas datasheet REJ03G1204-0200 (Rev.2.00).
Is HZC30TRF-E suitable for bidirectional ESD protection?
No - the HZC30TRF-E is a unidirectional Zener diode with anode and cathode terminals explicitly defined. It provides clamping only in reverse bias (cathode positive relative to anode). For bidirectional protection, two HZC30TRF-E devices must be connected in series opposition, or a dedicated bidirectional TVS like the PESD5V0S1BA should be selected instead.
What is the maximum allowable ambient temperature for continuous operation of HZC30TRF-E?
The HZC30TRF-E can operate continuously up to 125°C ambient temperature before power dissipation drops to zero, based on the linear derating curve in Fig.2 of the datasheet. At 100°C ambient, its usable power dissipation is reduced to approximately 50 mW, requiring careful thermal design in enclosed enclosures.
Does HZC30TRF-E meet RoHS and lead-free soldering requirements?
Yes - the HZC30TRF-E complies with EU RoHS Directive 2011/65/EU and supports standard Pb-free reflow soldering profiles (JEDEC J-STD-020). Renesas confirms environmental compliance in Section 10 of the datasheet notice and recommends verifying latest status via their website or authorized distributors.
How does the temperature coefficient of HZC30TRF-E affect its clamping performance?
The HZC30TRF-E exhibits a positive Zener voltage temperature coefficient of approximately +0.07 %/°C near 30 V, meaning its clamping voltage increases by ~21 mV per °C rise. This behavior is documented in Fig.2 (Temperature Coefficient vs. Zener Voltage) and must be accounted for in high-temperature applications where precise voltage limiting is required.
