Product details
Overview
5.0SMDJ30AHM6G from Taiwan Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in DO-214AB (SMC) package, rated for 5000W peak pulse power at 10/1000μs, 30V working standoff voltage, and clamps to 48.4V at 103A peak current. It features AEC-Q101 qualification, <1.0ps response time, and is used for I/O interface and AC/DC power supply surge protection.
For engineers reviewing the 5.0SMDJ30AHM6G datasheet, 5.0SMDJ30AHM6G pinout, 5.0SMDJ30AHM6G application, or 5.0SMDJ30AHM6G equivalent, key selection criteria include unidirectional clamping performance, 5000W surge rating, DO-214AB thermal capability (RθJL = 16°C/W), and automotive-grade reliability per AEC-Q101.
Technical Context
This TVS diode employs a stacked-die construction to achieve high peak pulse power handling while maintaining low clamping voltage. Its unidirectional configuration provides forward conduction capability with 5V VF @ 100A, enabling bidirectional protection when paired with complementary devices or used in DC-biased lines.
The device operates across –55°C to +175°C junction temperature range and exhibits a VBR temperature coefficient of 0.103 mV/°C, ensuring stable breakdown behavior under thermal stress. Its glass-passivated junction and JESD201 Class 2 whisker resistance support robust automated assembly and long-term field reliability.

Applications
| Automotive Body Control Module (BCM) | Industrial PLC Digital Input Card |
|---|---|
Use Scenario: Protects CAN/LIN bus I/O pins and sensor inputs against load dump and inductive switching transients in vehicle body electronics. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed between signal line and ground, clamping transients before they reach MCU GPIO or transceiver ICs. Use Value: Maintains 30V working standoff while limiting clamped voltage to 48.4V, preserving signal integrity and preventing latch-up in 3.3V/5V logic interfaces. | Use Scenario: Shields 24V digital input channels on programmable logic controller modules from field-wiring surge events. IC Role / Device Role / Timing Role: Primary overvoltage protection element at terminal block entry point, shunting surge current away from optocoupler input stage. Use Value: 5000W rating handles repetitive 24V system surges per IEC 61000-4-4; DO-214AB package supports high-current PCB trace routing. |
| AC/DC Power Supply Secondary Side | Telecom Line Interface Card |
Use Scenario: Suppresses flyback spikes and cross-talk transients on secondary-side DC outputs of offline SMPS units. IC Role / Device Role / Timing Role: Parallel-connected TVS across output rails, activated only during overvoltage fault conditions. Use Value: 48.4V clamping ensures safe margin below typical 48V rail overvoltage thresholds; RθJL = 16°C/W supports sustained thermal dissipation on 16mm × 16mm Cu pad. | Use Scenario: Guards Ethernet PHY or RS-485 transceivers connected to externally exposed ports against ESD and lightning-induced surges. IC Role / Device Role / Timing Role: First-line transient suppressor on differential pair or single-ended signal line, positioned before common-mode choke. Use Value: Sub-1ps response captures fast ESD events; unidirectional polarity avoids interference with DC biasing of line drivers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ30A | Lower peak power (600W), same DO-214AA package, 48.4V clamping at 12.3A | Not suitable for ISO 7637-2 Pulse 5-level protection; limited to low-energy ESD | Select 5.0SMDJ30AHM6G where 5000W surge immunity is required |
| SMCJ30A | Same DO-214AB package, 5000W rating, but 48.4V clamping at 103A and higher leakage (5 µA vs. 2 µA) | Compatible in layout and thermal design; slightly higher VC tolerance in some revisions | Acceptable alternative if tighter leakage spec is not critical |
Compared with SMBJ30A and SMCJ30A, the 5.0SMDJ30AHM6G delivers identical clamping voltage at full-rated current, superior leakage control (2 µA @ 30V), and AEC-Q101 validation-making it optimal for automotive and industrial systems requiring certified reliability and high-energy suppression.

FAQ
What is the maximum clamping voltage of the 5.0SMDJ30AHM6G at its rated peak pulse current?
The 5.0SMDJ30AHM6G has a maximum clamping voltage (VC) of 48.4 V at 103 A peak pulse current (IPP), measured under the standard 10/1000 μs waveform. This value is guaranteed across temperature and ensures downstream components remain within safe operating limits during surge events. The 5.0SMDJ30AHM6G achieves this clamping performance while maintaining a 30 V working standoff voltage, providing a robust 18.4 V margin above nominal rail voltage.
Is the 5.0SMDJ30AHM6G suitable for automotive applications?
Yes, the 5.0SMDJ30AHM6G is AEC-Q101 qualified and designed for automotive use. It supports junction temperatures from –55°C to +175°C and passes stress tests including high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing. The 5.0SMDJ30AHM6G is commonly deployed in body control modules, infotainment power supplies, and sensor interface circuits where ISO 7637-2 and ISO 16750-2 compliance is required.
What is the marking code for the 5.0SMDJ30AHM6G?
According to the manufacturer's datasheet, the 5.0SMDJ30AHM6G is marked "5PFK" on the device body. This 4-character code identifies the specific voltage variant (30 V VWM) within the 5.0SMDJxxAH family and is visible on the cathode-banded surface of the DO-214AB (SMC) package. The "M6G" suffix in the full orderable part number denotes tape-and-reel packaging (3,000 pcs/reel) and green molding compound.
How does the thermal performance of the 5.0SMDJ30AHM6G compare to similar SMC-package TVS diodes?
The 5.0SMDJ30AHM6G has a junction-to-lead thermal resistance (RθJL) of 16°C/W when mounted on a 16 mm × 16 mm copper pad, which is among the lowest in its class. This enables more efficient heat transfer than typical SMC TVS devices (often >20°C/W), supporting higher duty-cycle surge events. The 5.0SMDJ30AHM6G also achieves RθJC = 17°C/W, confirming effective internal die-to-case conduction-critical for sustained power dissipation in compact layouts.
Does the 5.0SMDJ30AHM6G have bidirectional capability?
No, the 5.0SMDJ30AHM6G is a unidirectional TVS diode, intended for use in DC-biased circuits where reverse polarity protection is not required. It conducts in forward direction up to 5 V at 100 A and clamps in reverse above VWM. For bidirectional protection, two 5.0SMDJ30AHM6G devices may be connected in series opposing configuration, or a dedicated bidirectional part such as 5.0SMDJ30CA should be selected instead.
