Product details
Overview
SMCJ160H from Taiwan Semiconductor is a unidirectional 1500W surface-mount transient voltage suppressor (TVS) diode in DO-214AB (SMC) package, with 160V working stand-off voltage (VWM), 178–218V breakdown voltage (VBR), and 287V maximum clamping voltage (VC) at 5.4A peak impulse current. It is AEC-Q101 qualified and meets ISO 7637-2 Pulse 1/2a/2b/3a/3b for automotive load-dump and ESD protection.
For engineers reviewing the SMCJ160H datasheet, SMCJ160H pinout, SMCJ160H application, or SMCJ160H equivalent, this device is selected for high-energy transient suppression in automotive power rails, industrial DC inputs, and telecom surge interfaces where fast response (<1.0 ps), low leakage (<1 µA @ 160V), and robust 1500W peak power handling are required.
Technical Context
The SMCJ160H employs a glass-passivated silicon junction optimized for unidirectional clamping, delivering sub-nanosecond response to transients while maintaining stable VBR tolerance (±5.6% min–max spread). Its thermal design supports 150°C junction operation with RθJC = 10°C/W and RθJA = 55°C/W, enabling reliable performance under sustained surge stress.
Designed for automated SMT placement, it features matte tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance. Polarity is marked by cathode band; moisture sensitivity level is J-STD-020 Level 1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 160 V - Maximum continuous reverse operating voltage before clamping initiates |
| VBR min/max | 178 V / 218 V - Breakdown occurs within this range at 1 mA test current; defines clamping onset threshold |
| VC @ IPPM | 287 V - Clamped voltage across device at 5.4 A peak impulse current (10/1000 µs waveform) |
| PPK | 1500 W - Peak pulse power dissipation capability per single non-repetitive surge event |
| IR @ VWM | <1 µA - Reverse leakage ensures minimal standby power loss and signal integrity in high-impedance circuits |
| TJ max | +150 °C - Maximum junction temperature rating enables use in under-hood automotive and industrial environments |
Pinout & Package
Package: DO-214AB (SMC), surface-mount, unidirectional configuration with cathode band marking. Case meets UL 94V-0 flammability rating; weight ≈ 0.210 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., ground or return path) in unidirectional TVS configuration |
| Cathode | Reverse-biased clamping terminal | Connected to protected line (e.g., 12V/24V rail); clamps transients toward anode when voltage exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|

| Fast response time | <1.0 ps rise-to-VBR delay ensures clamping activation before sensitive downstream ICs experience overvoltage |
| Low moisture sensitivity | J-STD-020 Level 1 rating eliminates need for dry-pack or bake-out prior to reflow soldering |
Applications
| Automotive Power Rail Protection | Industrial DC Input Surge Suppression |
|---|---|
Use Scenario: Protecting 24V battery-fed ECUs against load dump and alternator transients per ISO 7637-2 Pulse 5a. IC Role / Device Role / Timing Role: Unidirectional TVS placed between battery rail and input filter capacitor to clamp surges above 160V. Use Value: Limits peak voltage to 287V during 1500W transients, preventing damage to DC-DC controllers and microcontrollers rated ≤300V. | Use Scenario: Safeguarding programmable logic controller (PLC) 24V digital I/O modules from inductive switching spikes. IC Role / Device Role / Timing Role: Standoff-rated TVS on field-side input lines, absorbing repetitive 10/1000 µs surges up to 5.4A. Use Value: Maintains <1 µA leakage at 160V, avoiding false triggering of optocouplers or voltage comparators in high-impedance sensing paths. |
| Telecom Line Interface Protection | Renewable Energy DC Link Protection |
Use Scenario: Shielding PoE-powered equipment front-end from lightning-induced surges on Ethernet pairs. IC Role / Device Role / Timing Role: Paired unidirectional SMCJ160H devices on each data pair, referenced to common-mode ground. Use Value: Clamps common-mode transients to ≤287V while preserving signal integrity due to low junction capacitance (typ. <100 pF @ 0 V). | Use Scenario: Guarding solar inverter DC bus inputs against grid-switching transients and partial lightning coupling. IC Role / Device Role / Timing Role: Mounted directly at DC bus entry point, upstream of bulk capacitors and IGBT gate drivers. Use Value: Handles 1500W single-event surges without thermal runaway, supported by RθJC = 10°C/W for effective heatsinking to PCB copper. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ160A | Same VWM (160V), slightly higher VC (292V @ 5.3A), identical DO-214AC (SMA) package but smaller footprint and lower PPK (400W) | Lower energy handling limits use to lighter-duty consumer or non-automotive industrial applications | Select only if board space is constrained and surge energy remains below 400W; not AEC-Q101 qualified |
| Vishay SMF160A | Same VWM (160V), lower PPK (200W), DO-219AB (SOD-123FL) package, significantly smaller size and thermal mass | Insufficient for ISO 7637-2 Pulse 5a; suitable only for ESD-only or low-energy EFT scenarios | Use only for portable electronics or low-power sensor nodes where 200W clamping suffices and space is critical |
Compared with SMAJ160A and SMF160A, the SMCJ160H delivers 3.75× higher peak power (1500W vs. 400W/200W) and automotive qualification-making it the sole choice for under-hood 24V systems requiring full ISO 7637-2 compliance and robust thermal margin.

FAQ
What is the clamping voltage of the SMCJ160H under standard surge conditions?
The SMCJ160H has a maximum clamping voltage (VC) of 287 V when subjected to a 10/1000 µs waveform peak impulse current (IPPM) of 5.4 A. This value is measured per ANSI/IEEE C62.35 and represents the upper limit of voltage seen by downstream circuitry during a standardized transient event, ensuring protection for components rated up to 300 V.
Is the SMCJ160H suitable for bidirectional transient suppression?
No, the SMCJ160H is a unidirectional TVS diode, designed for clamping transients on positive-going voltage rails relative to ground. For bidirectional protection, Taiwan Semiconductor offers the SMCJ160AH variant (marked GHP), which provides symmetrical clamping in both polarities and uses the same DO-214AB package.
Does the SMCJ160H meet automotive qualification standards?
Yes, the SMCJ160H is AEC-Q101 qualified and explicitly tested to meet ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b requirements. Its construction-including glass passivation, JESD201 Class 2 whisker resistance, and J-STD-020 Level 1 moisture sensitivity-supports deployment in automotive powertrain and body electronics.
What is the thermal resistance profile of the SMCJ160H?
The SMCJ160H has a junction-to-case thermal resistance (RθJC) of 10°C/W and a junction-to-ambient thermal resistance (RθJA) of 55°C/W at standard mounting conditions. These values enable effective heat dissipation during transient events and support continuous operation up to +150°C junction temperature when PCB copper area is optimized per TSC's suggested pad layout.
How does the SMCJ160H differ from the SMCJ160AH variant?
The SMCJ160H is unidirectional with VF = 5.0 V at 100 A forward current, while the SMCJ160AH is bidirectional and shares the same VWM (160 V), VBR (178–218 V), and VC (259 V @ 6.0 A) ratings. The AH variant allows symmetric clamping without polarity concerns but exhibits slightly lower clamping voltage and higher IPPM due to dual-junction architecture.
