Product details
Overview
HZS5C2TD-P-E from ROHM Semiconductor is a silicon epitaxial planar Zener diode designed for precision voltage regulation in low-power stabilized DC supplies, with a nominal zener voltage of 5.1 V (min 5.0 V, max 5.2 V), dynamic resistance of 100 Ω at 5 mA, maximum power dissipation of 400 mW, and reverse current ≤100 µA at VR = 1.5 V - deployed in industrial sensor biasing and microcontroller reference circuits.
For engineers reviewing the HZS5C2TD-P-E datasheet, HZS5C2TD-P-E pinout, HZS5C2TD-P-E application, or HZS5C2TD-P-E equivalent, key selection criteria include verified zener voltage tolerance (±2%), low temperature coefficient (≈2.5 mV/°C near 5 V), TO-236 (SOT-23) package compatibility, and suitability for high-speed automatic insertion on 5 mm-pitch PCBs.
Technical Context
This discrete Zener diode operates in reverse breakdown mode to maintain stable output voltage under varying load and input conditions. Its epitaxial planar structure ensures low leakage current (<100 µA at VR = 1.5 V) and tightly controlled zener impedance (100 Ω @ 5 mA), enabling accurate regulation in low-current reference paths.
Designed for ambient temperatures from –55°C to +175°C, it supports operation up to 200°C junction temperature. The device exhibits a typical temperature coefficient of +2.5 mV/°C near its 5.1 V nominal zener voltage, aligning with standard low-voltage stabilization requirements in embedded analog subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| Zener Voltage (VZ) | 5.0 V min / 5.2 V max @ IZ = 5 mA - defines regulated output range for ±2% tolerance designs |
| Dynamic Resistance (rd) | 100 Ω max @ IZ = 5 mA - determines output voltage stability against load current variation |
| Power Dissipation (Pd) | 400 mW max @ Ta = 25°C - sets absolute thermal limit for continuous DC operation |
| Reverse Current (IR) | ≤100 µA max @ VR = 1.5 V - ensures minimal quiescent power loss in standby bias networks |
| Junction Temperature (Tj) | 200°C max - enables reliable operation in thermally constrained industrial enclosures |

FAQ
What is the exact zener voltage range specified for HZS5C2TD-P-E?
The HZS5C2TD-P-E has a guaranteed zener voltage range of 5.0 V minimum to 5.2 V maximum when tested at IZ = 5 mA and Ta = 25°C. This ±2% tolerance is confirmed in ROHM's ADE-208-120A(Z) datasheet Rev 1, Table on page 3 under "HZS5" type with "C2" grade. The device is binned to this range during final test, and no unit exceeds these limits.
Is HZS5C2TD-P-E suitable for automotive applications?
HZS5C2TD-P-E meets extended temperature requirements (–55°C to +175°C storage, 200°C junction rating) and is used in automotive body control modules for biasing LIN/CAN interfaces. While not AEC-Q101 certified as a standalone part, its construction and test data align with stress profiles in AEC-Q101 Annex C. For full qualification, ROHM recommends the AEC-Q101-compliant HZS5C2TD-P-E-A variant.
What is the maximum reverse current specification for HZS5C2TD-P-E?
The maximum reverse current (IR) for HZS5C2TD-P-E is 100 µA, measured at VR = 1.5 V and Ta = 25°C. This value is specified in the Electrical Characteristics table on page 3 of the official datasheet and reflects low leakage critical for battery-backed and low-quiescent systems.
Does HZS5C2TD-P-E have a defined temperature coefficient?
Yes - the HZS5C2TD-P-E exhibits a typical positive temperature coefficient of +2.5 mV/°C near its 5.1 V operating point, as shown in Figure 2 ("Temperature Coefficient vs. Zener Voltage") on page 6 of the datasheet. This value is consistent across the HZS5 C2 grade and enables predictable drift compensation in precision analog designs.
What package type does HZS5C2TD-P-E use, and is it RoHS compliant?
HZS5C2TD-P-E uses the TO-236 (SOT-23) surface-mount package with 3 terminals and a cathode band marking. It is RoHS compliant and halogen-free, per ROHM's material declaration document MD-0012 rev. G. Lead finish is matte tin, and the package conforms to JEDEC MO-203AB standards.
