Product details
Overview
5.0SMDJ22AHM6G from Taiwan Semiconductor is a unidirectional 22V standoff surface-mount transient voltage suppressor (TVS) diode rated for 5000W peak pulse power at 10/1000μs, with 24.4–26.9V breakdown voltage and 35.5V clamping voltage at 141A, designed for automotive-grade I/O protection in DC power rails and interface circuits.
For engineers reviewing the 5.0SMDJ22AHM6G datasheet, 5.0SMDJ22AHM6G pinout, 5.0SMDJ22AHM6G application, or 5.0SMDJ22AHM6G equivalent, key selection criteria include its AEC-Q101 qualification, DO-214AB (SMC) package, <1.0ps response time, 175°C max junction temperature, and verified clamping performance under ISO 7637-2 surge conditions.
Technical Context
This unidirectional TVS diode employs a stacked-die construction to achieve high peak pulse power handling while maintaining low clamping ratio (VC/VBR ≈ 1.42). Its photo-glass passivated junction ensures stable leakage (<5µA at 22V) and robust ESD immunity per IEC 61000-4-2 Level 4.
Thermal design is supported by RθJL = 16°C/W and RθJA = 61°C/W on a 16mm × 16mm Cu pad, enabling reliable operation up to 175°C junction temperature. The device meets JESD201 Class 2 whisker resistance and J-STD-020 Moisture Sensitivity Level 1.
Key Specifications

Applications
| Automotive Power Rail Protection | Industrial I/O Interface Protection |
|---|---|
Use Scenario: Protecting 24V supply inputs in engine control units (ECUs) against load dump and ISO 7637-2 Pulse 5a/b surges. IC Role / Device Role / Timing Role: Unidirectional TVS clamping transient energy to safe levels before it reaches downstream DC-DC converters and microcontrollers. Use Value: Limits clamped voltage to 35.5V, well below 40V absolute maximum ratings of common automotive PMICs and MCUs. | Use Scenario: Safeguarding RS-485 transceiver data lines in factory automation PLCs exposed to inductive switching noise. IC Role / Device Role / Timing Role: Fast-response shunt element diverting EFT bursts (IEC 61000-4-4) and surge currents away from communication ICs. Use Value: Sub-1ps response ensures clamping initiates before transceiver input stages experience destructive overvoltage. |
| DC Power Supply Input Stage | On-Board Charger (OBC) Auxiliary Circuitry |
Use Scenario: Secondary-side overvoltage suppression in 48V telecom and server PSUs after rectification and filtering. IC Role / Device Role / Timing Role: Standoff-rated TVS absorbing residual line transients that bypass primary-side MOVs and filters. Use Value: 22V working voltage aligns with nominal 24V output rails; 35.5V clamping avoids tripping downstream OVP circuits prematurely. | Use Scenario: Protecting auxiliary 12V logic supplies in EV on-board chargers subjected to battery reversal and jump-start events. IC Role / Device Role / Timing Role: Bidirectional-capable unidirectional TVS (with external series diode) providing reverse polarity and surge immunity. Use Value: AEC-Q101 qualification and 175°C rating ensure reliability in thermally constrained OBC enclosures near power semiconductors. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ22A | 400W PPPM, DO-214AC (SMA) package, higher RθJA (90°C/W) | Limited to lower-energy transients; unsuitable for ISO 7637-2 Pulse 5 | Select only for cost-sensitive non-automotive 24V systems with <1kW surge exposure |
| SMCJ22A | 1500W PPPM, same DO-214AB (SMC) package, lower clamping (33.2V @ 103A) | Insufficient for 5000W load dump; requires parallel devices for equivalent energy handling | Consider when board space allows multiple devices or when system-level testing confirms lower surge severity |
Compared with SMAJ22A and SMCJ22A, the 5.0SMDJ22AHM6G delivers 3.3× and 3.3× higher peak power handling respectively in the same SMC footprint, enabling single-device compliance with automotive load dump standards without layout redesign.

FAQ
What is the clamping voltage of the 5.0SMDJ22AHM6G at its rated peak pulse current?
The 5.0SMDJ22AHM6G has a maximum clamping voltage (VC) of 35.5 V at 141 A peak pulse current (IPP), measured under the standardized 10/1000 μs double-exponential waveform. This value is guaranteed across temperature and ensures protected circuits remain within safe operating limits during high-energy transients such as automotive load dump events.
Is the 5.0SMDJ22AHM6G suitable for bidirectional transient suppression?
No - the 5.0SMDJ22AHM6G is a unidirectional TVS diode optimized for DC line protection with polarity-sensitive mounting. For bidirectional applications like AC lines or differential buses, a dedicated bidirectional variant (e.g., 5.0SMDJ22CAHM6G) or external series diode configuration is required. Using the unidirectional 5.0SMDJ22AHM6G in reverse-biased AC scenarios may result in unintended conduction or failure.
Does the 5.0SMDJ22AHM6G require special PCB layout considerations?
Yes - to maintain its 5000W surge capability, the 5.0SMDJ22AHM6G must be mounted on a minimum 16 mm × 16 mm copper pad per lead, per the thermal test board defined in the datasheet. Short, wide traces to ground/power planes minimize inductance, and placement should avoid thermal isolation from adjacent heat sources or heatsinks that could compromise junction temperature margins.
What is the marking code for the 5.0SMDJ22AHM6G on the device body?
The 5.0SMDJ22AHM6G is marked with the code "5PEX" on its top surface, followed by green compound indicator "G", date code "YW", and factory code "F". This marking aligns with Taiwan Semiconductor's standard DO-214AB labeling convention and enables traceability to lot-specific electrical parameters and qualification data for the 5.0SMDJ22AHM6G.
How does the 5.0SMDJ22AHM6G perform under high-temperature operating conditions?
The 5.0SMDJ22AHM6G maintains full specification compliance up to 175°C junction temperature, with derating applied above 25°C ambient per Figure 2 in the datasheet. Its RθJL = 16°C/W and RθJC = 17°C/W enable effective heat transfer to PCB copper, allowing sustained operation in under-hood automotive environments where ambient temperatures exceed 125°C - a key reliability advantage of the 5.0SMDJ22AHM6G over lower-rated alternatives.
