Product details
Overview
P4SMA110CAH from Taiwan Semiconductor is a bidirectional surface-mount transient voltage suppressor (TVS) diode in DO-214AC (SMA) package, rated for 400W peak pulse power, 110V breakdown voltage (min 99V, max 121V), 89.2V working stand-off voltage, and clamps to ≤152V at 2.7A (10/1000μs waveform); used for surge protection in automotive DC/DC converters and industrial power supplies.
For engineers reviewing the P4SMA110CAH datasheet, P4SMA110CAH pinout, P4SMA110CAH application, or P4SMA110CAH equivalent, this page delivers verified electrical specs, AEC-Q101 qualification status, ISO 7637-2 compliance, clamping performance under standardized surge waveforms, and validated alternatives for bidirectional TVS selection in harsh-environment power systems.
Technical Context
The P4SMA110CAH is a bipolar (bidirectional) TVS diode designed to protect sensitive electronics against fast transient overvoltages such as ESD, lightning-induced surges, and load dump events. Its glass-passivated junction ensures stable breakdown behavior and low leakage (<1µA at 89.2V).
It operates across –55°C to +150°C junction temperature range, meets JESD201 Class 2 whisker resistance, and complies with ISO 7637-2 Pulse 1/2a/2b/3a/3b for automotive electronics. The device responds in <1.0ps and maintains clamping voltage ≤152V at rated 2.7A peak impulse current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR min/max | 99 V / 121 V at 1.0 mA test current - defines reliable conduction onset window for bidirectional surge clamping |
| VWM | 89.2 V - maximum continuous reverse voltage before significant leakage; sets system operating margin below breakdown |
| VC@IPPM | ≤152 V at 2.7 A (10/1000μs) - peak clamped voltage seen by protected circuit during worst-case surge |
| PPPM | 400 W - peak pulse power handling capability per single non-repetitive surge event |
| IR@VWM | <1 µA - ultra-low reverse leakage ensures minimal standby power loss and signal integrity in high-impedance nodes |
| TJ max | +150 °C - enables operation in under-hood automotive and high-temperature industrial environments |
| Package | DO-214AC (SMA) - industry-standard SMD outline with matte tin-plated leads, UL 94V-0 molding compound |
Pinout & Package
DO-214AC (SMA) surface-mount package with cathode band marking for polarity identification; bidirectional configuration means both terminals are symmetrical and interchangeable in circuit layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (Bidirectional) | Surge current path terminal | Either terminal conducts during positive or negative transients; no fixed anode/cathode assignment - symmetric clamping in both directions |
| Cathode Band (Marking) | Polarity indicator (for reference only) | Visible band denotes conventional cathode side; functionally irrelevant for bidirectional operation but aids visual orientation during placement |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD stress per JEDEC standards |
| ISO 7637-2 compliant | Withstands Pulse 1 (inductive load dump), Pulse 2a/2b (switching transients), and Pulse 3a/3b (line impedance stabilization network events) |
| Fast response time | <1.0 ps - limits voltage overshoot before clamping engages, critical for protecting fast-switching MOSFETs and gate drivers |
| Glass passivated junction | Ensures long-term stability of VBR and low parameter drift over temperature and lifetime |
| Moisture sensitivity level 1 | No floor life limitation or bake requirement before reflow - supports standard SMT assembly without special handling |
Applications
| Automotive On-Board DC/DC Converter | Industrial SMPS Input Stage |
|---|---|
Use Scenario: Protects primary-side controller ICs and MOSFET gates from load dump spikes and alternator transients in 12V/24V vehicle power systems. IC Role / Device Role / Timing Role: Bidirectional TVS placed across input bus to clamp ±100V+ surges within microseconds.

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110CA | 600W rating, DO-214AA (SMB) package, 10% higher VC (165V @ 3.2A) | Better power handling but larger footprint; requires PCB layout change | Select when higher surge margin is needed and board space allows SMB outline |
| 1.5KE110CA | 1500W rating, DO-201AD (Axial) through-hole package, slower thermal response | Not SMD-compatible; unsuitable for automated assembly or high-density layouts | Choose only for legacy through-hole designs or prototyping where reflow compatibility is not required |
Compared with P4SMA110CAH, SMBJ110CA offers higher peak power but demands larger PCB area, while 1.5KE110CA provides greater energy absorption at the cost of assembly compatibility and thermal performance - P4SMA110CAH balances compact SMD form factor, AEC-Q101 qualification, and precise 110V clamping for modern automotive and industrial power designs.

FAQ
What is the exact breakdown voltage range for P4SMA110CAH?
The P4SMA110CAH has a guaranteed breakdown voltage range of 99 V to 121 V at 1.0 mA test current, measured per ANSI/IEEE C62.35. This bidirectional specification applies equally in both polarities and is validated across –55°C to +150°C operating temperature. The P4SMA110CAH datasheet confirms this range under Note 1 of the Electrical Specifications table on page 3.
Is P4SMA110CAH suitable for automotive applications?
Yes, P4SMA110CAH is AEC-Q101 qualified and explicitly tested to meet ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b requirements. Its DO-214AC package, moisture sensitivity level 1, and –55°C to +150°C junction temperature rating make it appropriate for engine control units, body electronics, and ADAS power domains. The P4SMA110CAH product family documentation confirms automotive suitability on page 1.
What does the "CAH" suffix indicate in P4SMA110CAH?
The "CAH" suffix in P4SMA110CAH denotes a bidirectional configuration (C), automotive qualification (A), and halogen-free construction (H). Per TSC's ordering guide, "CH" or "CAH" identifies bipolar TVS types across the P4SMA6.8H–P4SMA200AH family. The P4SMA110CAH marking code is CZJ, and its bidirectional behavior is confirmed in the "Devices for Bipolar Applications" section on page 2.
What is the clamping voltage of P4SMA110CAH under standard surge conditions?
The P4SMA110CAH clamps to a maximum of 152 V at 2.7 A peak impulse current using the 10/1000 μs double-exponential waveform. This value is specified in the Electrical Specifications table (page 3) and reflects worst-case performance under standardized surge testing. The P4SMA110CAH maintains this clamping level while dissipating 400W, ensuring downstream ICs remain within safe operating voltage limits.
Does P4SMA110CAH require special handling during PCB assembly?
No, P4SMA110CAH has Moisture Sensitivity Level 1 per J-STD-020, meaning it can be stored indefinitely at ambient conditions and placed directly into standard reflow profiles without baking or dry-pack requirements. Its matte tin-plated leads comply with J-STD-002 for solderability, and the DO-214AC package is optimized for automated pick-and-place. These attributes are documented in the Mechanical Data section on page 1 of the P4SMA110CAH datasheet.
