Product details
Overview
P4SMA110CA from Taiwan Semiconductor is a bidirectional surface-mount transient voltage suppressor (TVS) diode in DO-214AC (SMA) package, rated for 400W peak pulse power, 158V maximum clamping voltage at 2.6A 10/1000μs surge, and 89.2V working stand-off voltage. It protects DC/DC converters, lighting drivers, and automotive power modules against ESD and ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.
For engineers reviewing the P4SMA110CA datasheet, P4SMA110CA pinout, P4SMA110CA application, or P4SMA110CA equivalent, key selection criteria include bidirectional clamping capability, 150°C junction temperature rating, compliance with J-STD-020 Level 1 moisture sensitivity, and verified performance under 10/1000μs surge waveforms per ANSI/IEEE C62.35.
Technical Context
The P4SMA110CA employs a glass-passivated silicon junction optimized for fast transient response (<1.0 ps), low leakage (<1 μA at 89.2V), and stable breakdown behavior across -55°C to +150°C. Its bidirectional configuration enables symmetrical clamping in AC-coupled or floating signal/power lines without polarity constraints.
Designed for automated SMT placement, it meets UL 94V-0 flammability and JESD201 Class 2 whisker resistance requirements. The device operates within strict thermal derating curves (Fig.2) and delivers repeatable clamping performance under repetitive 10/1000μs surges up to its 400W peak rating at TA = 25°C.

Use Scenario: Input protection for isolated 48V-to-12V buck converter in telecom infrastructure equipment. IC Role / Device Role / Timing Role: TVS absorbs energy from inductive kickback and EFT bursts coupled onto primary-side bus traces. Use Value: 400W peak power rating sustains multiple 10/1000μs surges without degradation, supporting >10-year field life. | Use Scenario: Transient suppression on Powered Device (PD) side of IEEE 802.3af/at-compliant PoE interfaces. IC Role / Device Role / Timing Role: Bidirectional clamping across data pair or power pair to prevent Ethernet PHY or PD controller damage.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110CA (Bourns) | Same DO-214AA package; 400W rating; VWM = 89.2V, VC = 158V - identical clamping performance but higher IR (5 μA) | Compatible in same PCB footprint but requires verification of leakage impact on ultra-low-power monitoring circuits | Select when sourcing flexibility is prioritized and leakage tolerance ≥5 μA is acceptable |
| 1.5KE110CA (ON Semiconductor) | Through-hole DO-15 package; 1500W rating; VWM = 89.2V, VC = 170V - higher power but larger size and slower response (~1.5 ps) | Not suitable for space-constrained SMT designs; used where board-level surge robustness exceeds 400W requirement | Choose only for legacy through-hole designs or where 1500W headroom justifies added volume and layout change |
Compared with SMBJ110CA and 1.5KE110CA, the P4SMA110CA offers optimal balance of SMT compatibility, 1 μA leakage, and precise 158V clamping - making it preferred for modern compact, low-power, and automotive-grade DC/DC and lighting systems requiring repeatable transient immunity.

FAQ
What is the maximum clamping voltage of the P4SMA110CA under standard 10/1000μs surge conditions?
The P4SMA110CA has a maximum clamping voltage (VC) of 158 V when subjected to a 10/1000μs surge waveform at its rated peak pulse current of 2.6 A. This value is measured per ANSI/IEEE C62.35 and guarantees predictable overvoltage limiting for downstream components such as DC/DC controllers and microcontrollers in automotive and industrial systems. The P4SMA110CA maintains this clamping performance across its full operating temperature range of -55°C to +150°C.
Is the P4SMA110CA unidirectional or bidirectional, and how is polarity indicated?
The P4SMA110CA is a bidirectional TVS diode, meaning it provides symmetrical clamping for both positive and negative transients without polarity dependence. Unlike unidirectional variants (e.g., P4SMA110A), it carries no cathode band marking and is identified by the "CA" suffix and "CYJ" marking code. This eliminates orientation concerns during automated placement and simplifies design in AC-coupled or floating power/signal paths where polarity reversal may occur.
Does the P4SMA110CA meet automotive transient immunity standards?
Yes, the P4SMA110CA is explicitly rated to meet ISO 7637-2 for automotive applications, covering Pulse 1 (inductive load disconnect), Pulse 2a/2b (switching transients), and Pulse 3a/3b (capacitive coupling and ignition noise). Its 158 V clamping voltage, 400W peak power rating, and guaranteed response time <1.0 ps ensure robust protection of ECUs, body control modules, and lighting systems against real-world vehicle electrical disturbances. The P4SMA110CA's TJ max of +150°C further supports under-hood deployment.
What is the moisture sensitivity level (MSL) and reflow profile compatibility for the P4SMA110CA?
The P4SMA110CA is rated MSL Level 1 per J-STD-020, meaning it can be stored indefinitely at ambient conditions and processed using standard lead-free reflow profiles (e.g., JEDEC J-STD-020D peak of 260°C) without pre-baking. Its DO-214AC (SMA) package uses UL 94V-0 molding compound and matte tin-plated leads compliant with J-STD-002 solderability requirements. This makes the P4SMA110CA ideal for high-volume automated assembly lines serving automotive and industrial customers.
How does the P4SMA110CA compare to the P4SMA110A in terms of electrical performance?
The P4SMA110CA differs from the unidirectional P4SMA110A primarily in symmetry and leakage: both share identical VWM (89.2 V), VBR (99–121 V), and VC (158 V), but the CA version supports bidirectional clamping while the A version is cathode-marked and unidirectional. The P4SMA110CA exhibits <1 μA IR at VWM versus the P4SMA110A's same spec - no practical difference in leakage. Designers select P4SMA110CA for AC lines or polarity-agnostic protection; P4SMA110A where ground-referenced unidirectional clamping suffices.
