Product details
Overview
HZS5C3TD-E from Renesas Electronics is a silicon planar Zener diode designed for precision voltage regulation in low-power stabilized power supplies, with a nominal zener voltage of 4.8–5.0 V, maximum power dissipation of 400 mW, dynamic resistance ≤100 Ω at 5 mA, and junction temperature rating up to 200°C - deployed in office equipment and industrial control power rails.
For engineers reviewing the HZS5C3TD-E datasheet, HZS5C3TD-E pinout, HZS5C3TD-E application, or HZS5C3TD-E equivalent, this page delivers verified electrical specs, package mapping to MHD (JEITA GRZZ0002ZC-A), cathode/anode terminal roles, and two validated alternative Zener diodes for supply-chain continuity and design flexibility.
Technical Context
The HZS5C3TD-E operates as a two-terminal voltage reference device using silicon planar Zener breakdown, optimized for DC stabilization under reverse-biased conditions with low leakage current (≤5 µA at VR = 0.5 V) and tight voltage tolerance (±0.2 V at 5 mA). Its thermal design supports ambient operation up to 125°C with derated power dissipation per Fig.3.
It belongs to the HZS Series' "B3" grade variant within the 5 V nominal range, featuring a zener voltage temperature coefficient near zero (≈0 mV/°C at ~5 V per Fig.2), enabling stable regulation across temperature without external compensation in non-critical applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 4.8–5.0 V at IZ = 5 mA - defines regulated output voltage window for feedback or clamp circuits. |
| Power Dissipation (Pd) | 400 mW max at Ta = 25°C - sets upper limit for continuous power handling in PCB-mounted linear regulators. |
| Dynamic Resistance (rd) | ≤100 Ω at IZ = 5 mA - determines load regulation error sensitivity to current variation. |
| Reverse Leakage Current (IR) | ≤5 µA at VR = 0.5 V - ensures minimal quiescent current in standby or low-power monitoring paths. |
| Junction Temperature (Tj) | 200°C max - allows high-temperature board placement near power components without thermal shutdown. |
| Package Type | MHD (JEITA GRZZ0002ZC-A) - 5 mm pitch compatible with high-speed automatic insertion equipment. |
Pinout & Package
Package: MHD (JEITA GRZZ0002ZC-A), molded plastic case with cathode band marking; dimensions: φD = 2.0 mm max, E = 2.4 mm max, L = 26.0 mm min; mass ≈ 0.084 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to regulated output node; polarity must be observed to maintain reverse-bias operation. |
| 2 | Anode | Connected to ground or lower-potential rail; completes bias path for Zener conduction. |
Key Features
| Feature | Design Value |
|---|---|
| Low zener impedance | rd ≤ 100 Ω enables <1% output deviation under ±1 mA load step in shunt regulator topologies. |
| Wide zener voltage spectrum | 1.6–38 V coverage across HZS Series allows single-family sourcing for diverse rail voltages. |
| High junction temperature rating | Tj = 200°C supports use in thermally constrained environments like enclosed industrial controllers. |
| Automated insertion compatibility | 5 mm pitch and MHD package enable direct integration into high-volume SMT/reflow-compatible assembly lines. |
Applications
| Industrial Power Monitoring | Office Equipment Voltage Clamp |
|---|---|
Use Scenario: Monitoring 5 V logic rail in programmable logic controller (PLC) I/O modules to detect overvoltage faults. IC Role / Device Role / Timing Role: Zener clamping element referenced to system ground, absorbing transient excursions above 5.0 V. Use Value: Prevents damage to downstream 5 V CMOS inputs by limiting peak voltage to ≤5.2 V during ESD or surge events. |
Use Scenario: Stabilizing reference voltage for analog-to-digital converter (ADC) in multifunction printers. IC Role / Device Role / Timing Role: Shunt regulator providing clean 4.9 V reference to ADC voltage reference pin. Use Value: Maintains ADC full-scale accuracy within ±0.5% over 0–70°C ambient due to low γZ near 5 V. |
| Test & Measurement Equipment | Home Electronic Appliances |
Use Scenario: Calibrating voltage thresholds in handheld multimeter front-end protection circuitry. IC Role / Device Role / Timing Role: Precision voltage limiter on input attenuator stage to prevent op-amp saturation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4733A (ON Semiconductor) | Same nominal VZ = 5.1 V, but wider tolerance (±5%), higher rd = 17 Ω typical, Pd = 1 W. | Higher power dissipation suits higher-current shunt loads but requires larger PCB footprint. | Select when >400 mW dissipation or looser VZ tolerance is acceptable. |
| BZX55-C5V1 (Vishay) | VZ = 5.1 V ±5%, rd = 60 Ω max at 5 mA, Pd = 500 mW, DO-35 package. | DO-35 axial lead form factor requires manual or wave-solder placement, not compatible with 5 mm pitch auto-insertion. | Choose for legacy through-hole designs or where MHD footprint is unavailable. |
Compared with 1N4733A and BZX55-C5V1, the HZS5C3TD-E offers tighter VZ tolerance (±0.2 V), lower thermal resistance via MHD package, and automated assembly readiness - making it optimal for space-constrained, high-reliability 5 V stabilization in modern industrial PCBs.

FAQ
What is the exact zener voltage range specified for HZS5C3TD-E?
The HZS5C3TD-E has a guaranteed zener voltage range of 4.8 V to 5.0 V when tested at IZ = 5 mA and Ta = 25°C, corresponding to the "B3" grade within the HZS5 type designation per Renesas datasheet REJ03G0184-0500 Rev.5.00. This tight ±0.2 V tolerance supports precision regulation without trimming in 5 V rail applications.
Does HZS5C3TD-E support automated PCB assembly?
Yes, the HZS5C3TD-E uses the MHD package (JEITA GRZZ0002ZC-A) with 5 mm pitch, explicitly designed for high-speed automatic insertion as stated in the "Features" section of the Renesas datasheet. Its standardized lead spacing and molded body ensure compatibility with pick-and-place and wave soldering processes common in volume manufacturing.
What is the maximum allowable junction temperature for HZS5C3TD-E?
The absolute maximum junction temperature for HZS5C3TD-E is 200°C, as specified in the "Absolute Maximum Ratings" table of the official Renesas datasheet. This rating permits operation in thermally demanding locations such as near power MOSFETs or transformers, provided PCB copper area and ambient conditions maintain Tj within limit.
How does the dynamic resistance of HZS5C3TD-E affect voltage regulation stability?
The HZS5C3TD-E exhibits dynamic resistance ≤100 Ω at IZ = 5 mA, meaning a 1 mA change in zener current causes ≤100 mV shift in regulated voltage. This value directly impacts load regulation performance in shunt configurations - lower rd yields tighter output voltage control under varying current demand.
Is HZS5C3TD-E compliant with RoHS and environmental regulations?
Yes, HZS5C3TD-E complies with the EU RoHS Directive as confirmed by Renesas Electronics' environmental compliance statements. The device contains no lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB), or polybrominated diphenyl ethers (PBDE) above threshold limits, and is suitable for environmentally regulated end products.
