Product details
Overview
HZC13TRF-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 13.2 V (min 12.47 V, max 13.96 V), 150 mW power dissipation, 35 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 data line clamping and I²C bus transient suppression.
For engineers reviewing the HZC13TRF-E datasheet, HZC13TRF-E pinout, HZC13TRF-E application, or HZC13TRF-E equivalent, key selection criteria include Zener voltage tolerance, low dynamic impedance for fast clamping response, ultra-small UFP package footprint, and high ESD robustness without external series resistance.
Technical Context
The HZC13TRF-E operates as a two-terminal voltage-reference clamp, conducting in reverse breakdown to limit transient overvoltage across protected nodes. Its Zener voltage exhibits a positive temperature coefficient of +0.07 %/°C near 13 V, enabling stable clamping performance across −25°C to +85°C ambient.
Designed for surface-mount surge absorption, it delivers 30 kV ESD immunity in both forward and reverse directions per IEC 61000-4-2, with a maximum reverse current of 0.5 µA at VR = 10.0 V and junction temperature limited to 150°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 12.47–13.96 V at IZ = 5 mA - defines precise clamping threshold for 12 V rail protection |
| Dynamic Resistance (rd) | 35 Ω max at IZ = 5 mA - ensures low-voltage overshoot during fast transients |
| Power Dissipation (Pd) | 150 mW at Ta = 25°C - supports continuous operation in compact PCB layouts without forced cooling |
| ESD Capability | ±30 kV (IEC 61000-4-2, C=150 pF, R=330 Ω) - eliminates need for secondary ESD components on sensitive interfaces |
| Reverse Current (IR) | 0.5 µA max at VR = 10.0 V - minimizes standby leakage in battery-powered systems |
| Junction Temperature (Tj) | 150°C max - enables reliable operation in sealed enclosures or high-ambient industrial environments |
Pinout & Package
HZC13TRF-E is housed in an Ultra Small Flat Lead Package (UFP, JEITA code PWSF0002ZA-A, SC-79 compatible), measuring 1.70 × 1.20 × 0.60 mm with 2.5 mg mass. The package features gull-wing leads optimized for reflow soldering and space-constrained designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to protected node (e.g., USB D+); conducts when voltage exceeds VZ |
| 2 | Anode | Ground reference terminal; must be tied to system GND with low-inductance path |
Key Features
| Feature | Design Value |
|---|---|
| Surge Absorption Optimization | Engineered for fast transient response in <100 ns events, with controlled avalanche behavior to avoid thermal runaway |
| Ultra-Small UFP Package | 1.70 × 1.20 mm footprint - reduces PCB area by >40% vs. SOD-323, enabling dense interface routing |
| Taped Delivery Format | Supplied in EIA-481-compliant embossed carrier tape (8 mm width) - compatible with high-speed pick-and-place assembly |
| High ESD Robustness | Withstands ≥30 kV contact discharge without parameter shift - qualifies for Class 4 IEC 61000-4-2 compliance out-of-box |
Applications
| USB 2.0 Data Line Protection | I²C Bus Transient Suppression |
|---|---|
Use Scenario: Clamping ESD strikes on USB D+ and D− lines in portable peripherals and host controllers. IC Role / Device Role / Timing Role: Standalone bidirectional voltage clamp placed directly at connector entry point. Use Value: Prevents latch-up or damage to USB transceivers (e.g., TUSB2036) without adding series resistance that degrades signal integrity. |

Use Scenario: Guarding analog input pins of 12-bit ADCs (e.g., ADS1115) against field-induced surges in factory automation nodes. IC Role / Device Role / Timing Role: Front-end overvoltage limiter before RC filtering stage. Use Value: Limits transient energy to <10 µJ, preventing ADC input stage saturation and measurement corruption. |
Use Scenario: Protecting 3.3 V or 5 V GPIOs of microcontrollers (e.g., RA4M1) from accidental hot-plug or cable discharge. IC Role / Device Role / Timing Role: Low-leakage (<0.5 µA) clamp active only during overvoltage events.

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-C13 | Zener voltage tolerance ±5%, 200 mW Pd, SOD-523 package (2.0 × 1.25 mm) | Larger footprint; higher power rating suits higher-energy transients but requires more board area | Select when higher surge energy handling is required and layout space permits larger package |
| MMBZ5242B | 13 V nominal, ±5% tolerance, 350 mW Pd, SOT-23 package (3.0 × 1.4 mm) | Higher power and larger size; not optimized for ESD-only events; lower ESD rating (±25 kV) | Choose for general-purpose voltage regulation where ESD robustness is secondary to power handling |
Compared with BZX584-C13 and MMBZ5242B, the HZC13TRF-E offers superior ESD immunity (±30 kV vs. ±25 kV), smallest footprint in its class, and tighter VZ tolerance (±5.3% vs. ±5%), making it optimal for space-constrained, high-reliability signal-line protection.

FAQ
What is the Zener voltage tolerance of HZC13TRF-E at 5 mA test current?
The HZC13TRF-E has a specified Zener voltage range of 12.47 V to 13.96 V at IZ = 5 mA, corresponding to a ±5.3% tolerance about the nominal 13.2 V value. This tight tolerance ensures predictable clamping behavior in precision 12 V rail protection circuits without requiring post-production binning or calibration.
Does HZC13TRF-E meet IEC 61000-4-2 Level 4 ESD requirements?
Yes, the HZC13TRF-E is rated for ±30 kV contact discharge per IEC 61000-4-2, exceeding Level 4 (±15 kV contact) requirements. Tested with C = 150 pF and R = 330 Ω in both forward and reverse directions, it maintains electrical parameters within spec after 10 pulses - confirming suitability for industrial and consumer-grade ESD-hardened designs.
What is the thermal derating behavior of HZC13TRF-E above 25°C ambient?
HZC13TRF-E follows linear thermal derating: power dissipation decreases from 150 mW at 25°C to zero at 150°C junction temperature. The derating slope is 1.25 mW/°C above 25°C, as confirmed by Fig.2 in the official datasheet. Designers must ensure PCB copper area and airflow keep Tj ≤ 150°C under worst-case transient duty cycles.
Can HZC13TRF-E be used in bidirectional signal lines like USB or RS-485?
Yes, the HZC13TRF-E functions bidirectionally due to its symmetrical Zener structure - clamping both positive and negative transients relative to ground. In USB 2.0 applications, one device per line (D+/D−) provides full ±30 kV ESD protection without polarity-sensitive orientation, unlike TVS diodes requiring dual-anode configurations.
What is the typical dynamic resistance of HZC13TRF-E and why does it matter?
The HZC13TRF-E has a maximum dynamic resistance of 35 Ω at IZ = 5 mA. This low rd minimizes voltage overshoot during fast transients (e.g., ESD pulses <1 ns rise time), ensuring clamped voltage stays within safe margins for downstream ICs - critical for protecting 3.3 V or 5 V logic interfaces without additional series impedance.
